Wide band long slot array antennas. Abstract: A continuous long slot aperture without discrete protruding elements was developed for phased array applications.
A low profile 10:1 (200–2000 MHz) wide band long slot array The antenna is ultra thin, with a total thickness of 8 cm including the ferrite tiles, about 5% of the wave length at 200 MHz. On average, the array has 2 dB loss over the 10:1 band. The antenna is designed for airborne missions that require very wide band and ultra-thin profile. A NOVEL WIDEBAND ANTENNA ARRAY WITH TIGHTLY COUPLED ... Although wideband phased array design is a long-standing topic of interest, progress has recently been made using endflre tapered slot antennas. The stripline fed tapered slot antenna, often called Vivaldi antenna, was flrstly introduced by Lewis etal. in 1974, and later was often employed as the antenna element to build up wideband phased
