A comparative study of micromachined and regular rectangular patch microstrip antennas at three frequencies i.e. 3,10 and 18 GHz in microwave frequency range on low and high RT Duroid substrate is presented. The promising micromachining technique is uses for improving the overall radiation performance of such antenna systems. In the present work the RT Duroid material is removed laterally underneath the patch antenna to produce a cavity that consists of a mixture of air and substrate with equal or unequal thickness. This paper presents the design of three types of antennas – the conventional regular patch antennas (type I), antennas of type II, in which the substance is removed just below the patch and the antennas of type III, those printed on mixed air-duroid cavity. Results are presented on bandwidth, input impedance, gain and radiation patterns for purposed antenna geometry.
