Abstract
As the mobile services have been increased, the interference of the neighboring base stations is increased and the PIMD(Passive Inter-Modulation Distortion) has been a main issue for the design of base station antenna systems. In this paper, it is proposed the PIMD test method for the active basestation antenna whose radiators are directly connected with main active parts including amplifiers, and we presents its test results using a developed active basestation antenna. From the results, the active basestation antenna has the better PIMD performance than conventional passive structure by 8.4dB. The proposed PIMD test method can be used to get the accurate PIMD test result because the test environment is very similar with real basestation.
