A lightweight X-band organic antenna array with integrated SiGe amplifier

This paper presents an X-band silicon-germanium (SiGe) low-noise amplifier (LNA) successfully integrated onto a 4×1 lightweight antenna array utilizing a multilayer liquid crystal polymer (LCP) substrate. Measurements show the packaged LNA had nearly no negative effect on antenna performance. The re...

Description
Summary:This paper presents an X-band silicon-germanium (SiGe) low-noise amplifier (LNA) successfully integrated onto a 4×1 lightweight antenna array utilizing a multilayer liquid crystal polymer (LCP) substrate. Measurements show the packaged LNA had nearly no negative effect on antenna performance. The resulting antenna gain of the antenna array with packaged LNA measured 25 dBi. A comparison of radiation patterns for the 4×1 antenna with integrated LNA and the baseline 4×1 antenna showed a 16.2 dB increase in antenna gain. The nulls and peaks of both antennas remained closely matched. Also, the 3 dB beam widths showed a 2 degree decrease in the H-plane and a 7 degree decrease in the E-plane.
