A wideband low profile phased array using long slot aperture was recently developed for radar and EW applications. A prototype UHF array with 4 x 8 (32) elements (1.12 m x 2.24 m x 23 cm) was built and tested for 150-600 MHz operation. Array patterns, gain, and cross-pol level were measured. Excellent performance was observed. The array is 23 cm thick, and it weighs 7 kg (2.8 kg/m(2)). Lossy loading material may be used to make it thinner, but this is believed to be the lightest and thinnest UHF array reported for wideband applications without gain penalty.
