Adaptive antenna for handheld GPS receivers
Andrew S. C. Svendsen, Inder Jiti Gupta · IEEE/ION Position, Location and Navigation Symposium · 2010
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 performance of a simulated and experimental antenna is compared and found to be in agreement. Finally, the effect of aperture reduction on the antenna performance is examined.
