Introduction：
The STLP 9128 C Stacked Log Periodic Antenna is a high power output antenna manufactured by Schwarzbeck, Germany and authorized for sale by EUTTEST in Shenzhen, China. This antenna supports frequencies up to 4GHz and up to 3kW forward power input.
Stacked log-periodic antenna is composed of two normal log-periodic antennas, normal log-periodic antennas have the product characteristics of flat gain and low SWR, after using two log-periodic antennas in stacked design, it helps to focus the directional map of the H-plane to a certain extent, which typically improves the gain. The gain will be increased by 2-3 dB compared to a normal LPDA, which is especially important for immunity testing where maximum field strength and good field uniformity are required. The E-plane and H-plane of this antenna have almost the same 3 dB flap width, thus providing a good radiating area while minimizing the effects of ground reflections. In addition, it has excellent cross-polarization rejection.
