Microstrip patch antennas (MPAs) are utilized in many applications as they are easy to produce and are thin, versatile, light weight, cheap, and reliable. One of the drawbacks of MPAs, however, is their narrow bandwidth, typically three to ten percent. Fortunately, a perturbation exists capable of resolving this issue known as the U-slot which can increase the operational bandwidth of a single layer MPA to around 30 percent. Often it is reported that the wideband performance of this structure results from the existence of two resonators, the patch and the U-shaped slot. While this is true, the very nature of …
