Abstract :
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.
