Test Equipment Description

Stacked Logarithmic-Periodic Broadband Antenna for Linear polarised RX- and TXapplications in the microwave frequency range. The antenna structure is made of laser-cut brass. For protection of the fine antenna structure against damage the antenna is equipped with a low loss plastic protection cover. The STLP 9149 is especially suitable for Immunity Testing acc. to IEC 61000-4-3 because of its good field uniformity. Further outstanding characteristics of the STLP 9149 are the wide bandwidth, the nearly constant high gain, very good impedance matching as well as equal beamwidth in E- and H-plane.
