IEEE Region 10. Technical Conference (TENCON) - CCT & SP & SAT LOCAL CONFERENCE / REGIONAL CONFERENCE
24 Nov 2016
An electronically beam steering antenna for GlobalNavigation Satellite Systems (GNSS) is presented. The antennaprototype consists of a closely spaced (center-to-center distance of0.35λ) 1×4 circularly polarized patch array, a broadband RFsignal weighting module, and a set of control software as well asfirmware. The RF module covers 1.1 GHz to 1.7 GHz to enablemulti-band GNSS signal control. The beam can be steered from -45° to +45° with an axial ratio of 2.5 dB.
