A microwave antenna transmits/receives RF signals (typically 1-300GHz) by converting electrical pulses to electromagnetic waves (Tx) or vice versa (Rx). For example, 5G mmWave antennas (24-47GHz) use patch radiators: feed lines inject 10-20dBm signals, exciting surface currents to radiate waves. With 15-20dBi gain and >80% efficiency, they focus beams (1-5° width) to boost signal strength […]

A 5G waveguide duplexer isolates transmit (TX) and receive (RX) signals in mmWave bands (e.g., 24-47GHz), critical for avoiding self-interference. Using resonant cavities or E-plane filters, it achieves >50dB isolation between TX (up to 100W power) and RX (<-100dBm sensitivity), with insertion loss <1.5dB, enabling simultaneous operation in high-bandwidth (100MHz+) 5G NR links.​ What is

LPDA antennas excel in wideband signal interception (70MHz–18GHz), with 10–15dBi gain; used in electronic warfare to track 5+ comms protocols simultaneously, exploiting their frequency-agnostic radiation pattern for consistent, multi-spectrum surveillance.​ How an LPDA Works A simple half-wave dipole antenna is designed to be ​​highly efficient at one specific frequency​​. For example, a dipole cut for
