Beamforming using phased array antennas is a common technology for radar and electronic warfare in the aerospace and defense industry. In satellite communications and 5G NR, phased array beamforming is becoming a default concept. Integrated RF beamforming ICs include phase and gain adjustment per path as well as amplification capabilities for the TX and RX channels. Such beamformer ICs support four or more antenna elements from one input signal. Full characterization and calibration requires simultaneous assessment of all ports. This article discusses the process of verification for these beamformer ICs for phased array antennas.
Air defense missiles typically require a proximity fuse, priming the missile warhead to detonate when the missile is close enough to the target. One of the ways that such a proximity fuse can be implemented is with a small radar that is used in short-range low-power mode.
At shopping malls, consumers also are able to find various types of entertainment, dining options, spa services, childcare, etc. This white paper presents Bird’s Distributed Antenna Systems (DAS) solution for meeting these wireless communications difficulties.
This app note describes how to design a transmit/receive module with a 2x2 phased-array antenna operating in the 8 to 12 GHz range. This paper also covers capabilities within the NI AWR Design Environment platform, including multi-technology and circuit/system co-simulation.
Groundbreaking innovations on antenna technology, based on a collaboration between Lockheed Martin Space and Penn State, are now under consideration for use in the next generation of GPS satellite payloads.
Pharad has introduced a new Unmanned Air Systems (UAS)/Drone antenna based on its proprietary Peel & Stick Appliqué antenna technology.
Antennas made of carbon nanotube films are just as efficient as copper for wireless applications, according to researchers at Rice University's Brown School of Engineering. They're also tougher, more flexible and can essentially be painted onto devices.
