STLP 9128 E special - Stacked Log Periodic Antenna

The STLP 9128 E special is nearly identical to the STLP 9120 E but with folded longest elements and a smaller structure angle.

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 are required. The beamwidth 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 STLP 9128 E special is excellent. The fastlinks allow disassembling of the rear elements without any need for further tools within a few seconds. These fastlinks divide the antenna into five parts, which can be stored and transported easily.

Main Application: Generation of defined high field strength levels for radiated immunity testing.
