Title :
Microstrip antennas for GPS applications

Ingalls, Mark W. ; Smith, Dan
Abstract :
Design and testing of circularly polarized probe-fed single-layer microstrip patch antennas for GPS applications are presented. An-echoic chamber antenna range measurements on a variety of patch elements is discussed and tabulated showing the effects of element size, around plane size, symmetry, and proximity of scatterers (such as a battery). "Real world" performance of selected patch element and ground plane combinations are discussed and tabulated. These results are intended to compare the design of an element for its intended environment and its antenna range measurements to the performance of a complete system.
