Multi path and jam resistant antennas for GNSS receivers

Abstract

In GNSS applications, multipath errors and jamming threats are still one of the major error sources or service unavailability in conventional receivers. Antenna array algorithms are introduced as a possible solution to both these threats. Nevertheless, the performances of such techniques are degraded when considering technological defects and especially mutual coupling. To face this limitation, a HIS based antenna array design is presented. This design aims at minimizing the array mutual coupling coefficients while not increasing the size of the array
