A problematic base station can be replaced, but a cable and antenna system is not so easy to replace. This article covers fundamentals of cable and antenna analysis measurements: return loss, cable loss, and distance-to-fault (DTF).
What makes communication so challenging in an airport is its large coverage area and high-capacity requirements. That’s the challenge YYC Calgary International Airport faced when it built its new international terminal.
Distributed Antenna Systems (DAS) are used to provide strong and reliable wireless connectivity in location where connectivity is a problem with standard wireless routers or cellular connectivity. This app note discusses the use of DAS for IoT, cellular and other wireless applications.
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.
Pharad has introduced a new Unmanned Air Systems (UAS)/Drone antenna based on its proprietary Peel & Stick Appliqué antenna technology.
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.
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.
