ANALYSIS OF SLOT COUPLED MICROSTRIP PATCH ANTENNAS A ... In this thesis, planar rectangular microstrip patch antennas fed by different techniques are analyzed using Method of Moments/Spectral Domain Green’s function method. Specifically, formulations for the analysis of radiation from microstrip line fed, proximity coupled and slot coupled microstrip patch antennas are Effect of the Different Shapes: Aperture Coupled ... Abstract: The paper reviews the effect of the different shapes on the aperture coupled microstrip slot antenna. Aperture coupled microstrip slot antenna couples the patch antenna with microstripline through an aperture. One effective way to increase the impedance band-width is to change the patch shape, feed shape and the slot shape.

Chen and Zhang [23] described Bandwidth enhancement of a microstrip-linefed printed wide-slot antenna with a fractal shaped slot. A novel monopole antenna with a self-similar slot for wideband applications [25] is designd by Song and Zhang.
etc. It is well known that the major drawback of a microstrip antenna is its narrow bandwidth [2]. One of the popular techniques for broadening the patch antenna bandwidth is to incorporate U-slot on its surface [1]. In this communication [4] a microstrip patch antenna using dual U-slot with broad bandwidth (>37%) is proposed.
