摘要：
An electronically beam-steering antenna for Global Navigation Satellite Systems (GNSS) is presented. The antenna prototype consists of a closely spaced (center-to-center distance of 0.35 lambda) 1x4 circularly polarized patch array, a broadband RF signal weighting module, and a set of control software as well as firmware. The RF module covers 1.1 CHz to 1.7 GHz to enable multi-hand GNSS signal control. The beam can be steered from -45 degrees to +45 degrees with an axial ratio of 2.5 dB.
