Step inside this REALM that’s full of measurement possibilities. This room is called the Robotically Enhanced Antenna Laboratory for Metrology, aka REALM. Here, NIST researchers use NIST-pioneered robotic antenna measurement systems called the Large Antenna Positioning Systems (LAPS) and the Configurable Robotic MilliMeter-wave Antenna (CROMMA) that essentially are really accurate radio-frequency holographic cameras for doing antenna measurements. The lab is based at our campus in Boulder, Colorado, and serves three key areas: 📡 Standards development and antenna calibration services 📡 Engagement with stakeholders in industry and government agencies 📡 R&D Why is this work important? Antennas are everywhere in modern day life, from cellphone towers to satellites in space. The measurements done on them can be traced back to NIST through our reference antennas and measurement methodologies. Organizations, such as aerospace manufacturers, use them to verify that the antennas they design or are producing are working as intended. The room is also filled with various cones made of foam on the floors and ceilings, which absorb the microwave wavelengths emitted from the antennas to ensure the measurements aren’t distorted. These features make the room similar to an anechoic chamber or quiet room. #Electronics #Antennas #Measurements #Robotics #Metrology

Creating a Pure Copper Tensor Electroculture Antenna! ⚡️🌱⚡️ Electroculture is an alternative gardening technique that uses conductive materials; usually copper wire coiled into antennas or stakes, and then inserted into the soil to capture atmospheric energy (otherwise known as aether) and enhance natural magnetic fields! ⚡️ We’ve made this using a twisted tensor wire made with the Sacred/Royal Egyptian cubit which resonates at 144MHz and is powerful for boosting plant growth and promoting soil health! 🌱 It has been used throughout recent history to increase crop yields and reduce the need for fertilisers and other chemicals often used in agriculture. 🍎 These are available on our website - synergyhealingtools.com - link in bio! ✨ Comment ELECTROCULTURE for more information! 🌱⚡️

This triangle works as an antenna.📡 The Sierpinski Triangle, a fascinating design made up of triangles of varying sizes, is a fractal—a repeating pattern that looks the same at every scale. Its mathematical properties are used to design antennas that can handle multiple frequencies. In this video, we explain how this fractal shape works as an antenna. — Learn math the right way: Signup for a FREE trial class, grades K-12.

Building large antennas in remote or hard-to-reach areas often involves helicopters, turning the entire process into a precise aerial operation rather than a traditional construction job. Instead of cranes or scaffolding, experts rely on helicopters to lift and position heavy antenna components—like steel towers, panels, and transmission equipment—directly onto mountaintops or tall structures. Each piece is carefully pre-assembled on the ground, then flown in sections, where even slight misalignment can affect signal performance. The pilots and ground engineers work in perfect coordination, communicating constantly as components hover mid-air. The helicopter must remain incredibly stable while technicians guide parts into place, sometimes securing bolts while the structure is still suspended. Wind, altitude, and weight balance all play critical roles, making this process both physically demanding and mentally intense. One small mistake could mean delays, damage, or even danger. This method is commonly used for telecommunications towers, radar systems, and broadcasting antennas, especially in rugged terrains where roads don’t exist. It’s a blend of aviation skill and engineering precision—where machines and humans work together in the sky to build the invisible networks that keep the world connected. follow for more #antena #physics #engineering

Aircraft antennas might be easy to overlook, but they're essential for communication, navigation, and safety! 🛰️📡 From talking to air traffic control to navigating complex routes, each antenna on an aircraft has a specific role, ensuring pilots have the information they need in real time. Here’s a breakdown of the key antennas and what they do. 1. VHF Communication Antennas: These are the main communication antennas on most aircraft. They operate in the VHF (Very High Frequency) range and allow pilots to communicate with air traffic control over relatively short distances. Usually located on top of the fuselage or under the belly, VHF antennas ensure clear voice communication up to about 200 miles, depending on altitude. 2. HF Communication Antennas: For longer-distance communication, especially during trans-oceanic flights, HF (High Frequency) antennas come into play. These antennas can “bounce” signals off the ionosphere, making them capable of spanning thousands of miles. You might spot HF antennas as long, thin wires along the fuselage or near the tail on larger aircraft. 3. GPS Antennas: GPS antennas are vital for accurate navigation, providing real-time positioning data to the cockpit. They’re usually small, dome-shaped antennas on top of the fuselage, designed to pick up signals from GPS satellites. 4. Weather Radar Antennas: Located in the nose, these antennas scan ahead for weather patterns, helping pilots avoid severe weather. The radar data is displayed on cockpit screens, showing precipitation levels, storm cells, and turbulence. 5. DME Antennas: DME (Distance Measuring Equipment) antennas allow the aircraft to determine its distance from ground-based navigation aids. Paired with VOR (Very High Frequency Omnidirectional Range) antennas, they enable precise navigation, particularly during approaches. 6. TCAS Antennas: TCAS (Traffic Collision Avoidance System) antennas, usually on the top and bottom of the fuselage, detect nearby aircraft to prevent mid-air collisions. ......

A jacket that connects you to space 🌌 Incorporating antennas into different types of fabrics and surfaces has been a long-term challenge, with their delicate components traditionally being difficult to fold. With our support, the Finnish company Stealthcase overcame these obstacles by finding a low-cost and scalable method to imprint the antenna coating onto textile without compromising its conductivity. Once perfected, the outdoor clothing brand @haltiworld designed a jacket to integrate the antenna, putting the technology to the test in real-world conditions. To trial the jacket, a team carried out a six-hour trek to the summit and back of Halti, Finland’s highest mountain (although its peak lies over the border in Norway). The team divided in two groups; those hiking Halti’s peak and those staying at lower altitudes. Along the route, the first team paused at intervals to test connectivity by sending and receiving text messages with the second team. They demonstrated the two-way communication capabilities of the wearable antenna through a direct link to a satellite over 35 000 km away. Remarkably, the satellite link held strong even in spots where the terrain was expected to block the signal. 📹 @europeanspaceagency 🎞️/📸 ESA, Stealthcase

At the extreme, we talked about the big antennas you need for these very low-frequency, long-wavelength signals. At the extreme, the only wavelengths that can penetrate water are the very low-frequency, long wavelengths. And so submarines will dangle an antenna that’s one kilometer long off their back to receive those. And again, we can receive that on something the size of a sugar… Teasing out the story of quantum clocks.... . #technology #tech #engineering #telecommunications #radiowaves #physics #defencetech #navy #submarines #deeptech #innovation #uktech #ustech #thinkingonpaper
