The stacked Log Periodic Dipole Antenna (Stacked LPDA) consists of two ordinary Log.-Per. structures. The excellent characteristics (flat gain over a large bandwidth, low SWR) of the ordinary LPDA designs could be maintained using the stacked LPDA design. The stacked design helps to focus the directional pattern of the H-plane somewhat, resulting in a typical gain improvement of 2.5 dB compared to an ordinary LP antenna. This is especially important for immunity testing, where a maximum field-strength and a good field uniformity is required. The beam width in the E-Plane and the H-plane are nearly identical, providing an optimized illumination of the EUT with minimized ground reflection influence. Further the cross polar rejection of the AXL-80ES is excellent. The fast-links allows to disassemble the rear elements without any need for further tools within a few seconds. These fast-links divide the antenna into five parts, which can be stored and transported easily.
