Abstract: | An adaptive antenna for handheld GPS receivers is presented. The antenna has a small aperture, small volume, and is lightweight. The antenna uses four spiral elements to provide broadband satellite coverage and can also be used in conjunction with a space-time adaptive processor (STAP) for interference suppression. The antenna with integrated feed is easy to fabricate as well. The performance of a simulated and experimental antenna is compared and found to be in agreement. Finally, the nulling performance of the antenna is examined for a few simple interference scenarios. |
