Shorted microstrip patch antenna

Abstract

In this thesis, electrically small microstrip patches incorporating shorting posts are thoroughly investigated. These antennas are suitable for mobile communications handsets where limited antenna size is a premium. In particular, it is shown that the zero mode of the unloaded MSA (Microstrip Antenna) plays a central role for reducing the lowest operation frequency of the loaded MSA. The studies carried out allow the determination of all relevant antenna parameters for different post specifications and can easily be extended for different patch architectures.
