Performance Analysis of Cut Feed Rectangular Microstrip Patch Antenna by Varying Feeder Length and Width

One of the important tasks of designing a cut feed microstrip patch antenna is to select length (L f ) and width (W f ) of the feeder. There is no well-known formula to find out the length and width of the feeder directly. So, in order to select the appropriate length and width of the feeder, an antenna designer should have some knowledge about the impact of feeder length and width variation on the performance of the antenna. This paper represents the effect of variations in feeder length and width of a cut feed rectangular microstrip patch antenna on the performance parameters like resonance frequency, gain, directivity, bandwidth, return loss, efficiency, axial ratio etc. All the parameters were simulated by using momentum 3D planar electromagnetic simulator 2009.
