Study of Micristrip Patch Antenna with Truncated Corners

Abstract

In the last few years the Global Positioning System (GPS) has been used in a
variety of applications for which new and more restrictive requirements in the design of
the receiving antenna have been introduced. In particular, for high precision GPS
application, such as differential GPS, GPS-based space graft altitude determination or
geodetic surveying, receiving antenna with superior rejection to multipath signals is
required. Multipath arises when the GPS transmitted signal takes different paths to
receiving antenna and being the signals from these paths added with different spaces, this
result in a significant amplitude and phase distortion.
