摘要：An antenna is a device that is used to convert guided electromagnetic waves into EM waves. Significant developments have been done to design compact, minimal weight, low profile antennas. The technologist has focused into the design of microstrip patch antennas resulting in various microstrip antenna. Microstrip antennas may be made of any geometrical shape and dimension. In this project microstrip patch antenna has a radiating circular patch on one side of a dielectric substrate having very small thickness and has an infinite ground plane on the other side Dielectric materials may be considered as the backbone of microstrip antennas. Here we have designed the circular microstip patch antenna for three feeding techniques with different substrates for 7Ghz & 2.4 Ghz frequencies by using Ansoft HFSS Software. According to the simulation results circular microstrip antenna designed for 7GHz with Aperture coupling feed is more efficient with the substrate rogers RT/duroid 5870 (tm) having dielectric constant 2.33. In both the coaxial feed and microstrip line feed cases the results showing the good impedance matching between the feed line and the antenna. Coaxial feeding requires number of trial and error methods for getting impedance match at a particular feed position. For the microstrip line feeding impedance matching depends on the inset depth. Both shows the good agreement.
