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 A low profile 10:1 (200–2000 MHz) wide band long slot array A low profile 10:1 band (200-2000 MHz) long slot array was developed for radar and EW applications. For performance demonstration, a prototype array of 11times11 elements (1.2 m times 1.2 m) was ...

Gerini TNO – Defence, Security and Safety Oude Waalsdorperweg 63, 2597 AK, The Hague, The Netherlands A low profile 10:1 (200–2000 MHz) wide band long slot ... Abstract: A low profile 10:1 band (200-2000 MHz) long slot array was developed for radar and EW applications. For performance demonstration, a prototype array of 11times11 elements (1.2 m times 1.2 m) was built and tested. It is backed by a ferrite loaded ground plane, separated from the aperture by 5-cm air gap. Radar Basics - Slot Antennas
