Introduction：
STLP 9148 is a stacked microwave log-periodic antenna manufactured by Schwarzbeck (Germany) and authorized to be sold by EUTTEST (Shenzhen). The test frequency covers a wide band from 700MHz to 20GHz, and this antenna is generally recommended for microwave transmitting and receiving applications above 1GHz. The structure of this log-periodic antenna is made of laser-cut brass, and a removable protective shell is added on the outside to protect the antenna mechanism. EMC testers can use this antenna in a microwave dark room, and the test distance can be moved from 0.5m to 3m position, and you only need to inject 50W of power to get an E-field strength of 100V/m in the front of the antenna, for details, please check the following graphs of input power For details, please see the graph of input power and electric field strength below.
