Spatial periodic array with frequency-selective bandpass response for GPS and DCS1800 mobile communications

Abstract

This thesis explores the design and implementation of periodic arrays with frequency selective response for a novel antenna that is developed for low frequency microwave communications usage. It begins with a review of the physics and the analytical techniques essential for the design of infinite periodic arrays. Several test cases are implemented to verify the accuracy of the design approach. A unique test case is constructed to illustrate, with the aid of visualisation tool, the field and wave phenomena associated with the grating lobe, bandstop and bandpass conditions that are otherwise too abstract to appreciate.
