Abstract:
In this paper we are comparing the resent development on the micro strip patch antennas to increase their bandwidth by the different types of methods. First method is a 60 GHz antenna built-up on a Silicon membrane with an upper BCB (Benzo Cyclobuten dielectric) thin film deposit and excited with a U or T-shape micro strip feeder via a dielectric gap. Second method is the compound techniques to broaden the bandwidth of micro strip patch; a new type of stacked micro strip patches antenna which increases the frequency bandwidth obviously is investigated. Now the third one is an open circuited stub connected in shunt with the micro strip feed line. To further enhance the bandwidth of the antenna, an additional shunt stub and multiple shorting pins are incorporated. The design of the aperture coupled antenna with shunt stubs and shorting pins is described.
