Four cost-reduction technologies for phased array antenna design: 1) Use a multi-layer PCB integrated feed network to reduce interconnect components; 2) Use low-cost LCP materials (dielectric constant 2.9±0.1); 3) Optimize the unit spacing to 0.5λ~0.7λ to reduce the number of array elements; 4) Introduce digital beamforming to reduce the number of RF links. Unit Simplification […]

Six major criteria for selecting phased array antenna manufacturers: 1) frequency coverage (e.g. 2–40 GHz); 2) gain accuracy (within ±1 dB); 3) beam switching speed (<1 μs); 4) sidelobe suppression capability (<-30 dB); 5) environmental adaptability (-40 to +85°C); 6) support for customized interfaces (e.g. SPI, LVDS) Phased Array Lessons Last summer’s Houston ground station
