Abstract

A microstrip patch antenna employing a novel feed arrangement is presented. By using the slotline to microstrip coupling, energy is coupled to the radiating patches via a continuous slotline in the microstrip ground plane. This allows the patches and the feeding slotlines to be fabricated on a single substrate minimising device areas in MMICs. Using Hewlett Packard´s high frequency structure simulator (HFSS) the electric and magnetic field distribution on a single patch design have been analysed. The results of measurements performed in an anechoic chamber are presented which show the radiation characteristics of a 10 GHz prototype antenna using the new feed mechanism
