Abstract
The characteristics of a consumer‐grade global navigation satellite system (GNSS) antenna are very different from those used in aviation, surveying, or space applications. The GNSS antenna must be sensitive to the GNSS signals' center frequency and must have sufficient bandwidth to efficiently receive these signals, but there are several other performance characteristics that are important. This chapter discusses several key antenna performance characteristics with information pertaining to their application. A few computational electromagnetic models and methods that are useful for GNSS antenna design are presented. Adaptable phased‐array antennas, often called smart antennas or controlled reception pattern antenna in the GNSS community, have the capability to control and change the net antenna radiation pattern characteristics as a result of sensing the environmental conditions that are presented to the GNSS antenna and/or receiver system. Finally, the chapter addresses issues regarding calibration of GNSS antennas and compensation for group and phase delays.
