Microstrip antennas can be used in applications which requires high-performance compact low-cost planar antennas such as imaging arrays andThe real part of the aperture-coupled microstrip antenna input impedance is fixed by the length of the slot and is designed to be 50 .
that addition of superstrate layer to U slot patch antenna is enhancing the bandwidth of aperture coupled microstrip antenna, but this result is not as encouraging as in the case of probe fed microstrip antenna with U slot and addition of superstrate layer on it. This may be due to the fact that Design of Aperture Coupled Micro-Strip patch Antenna for ... A microstrip antenna is basically a low profile antenna with a number of advantages over other antennas like small in size, light weight, inexpensive to fabricate.[1] A microstrip antenna with aperture coupled feeding technique is used here as it is one of the most important method for exciting microstrip antenna

One of the useful features of the aperture coupled microstrip antenna is that it can provide substantially improved impedance bandwidth. While single layer probe fed element has limited impedance bandwidth of 2−5%, an aperture coupled element with modified slot is able to increase the impedance bandwidth [4]. Microstrip U-Slot Aperture Coupled Antenna for Wimax Application that addition of superstrate layer to U slot patch antenna is enhancing the bandwidth of aperture coupled microstrip antenna, but this result is not as encouraging as in the case of probe fed microstrip antenna with U slot and addition of superstrate layer on it. This may be due to the fact that
The antenna exhibits wideband characteristics that depends on various parameters such as U slot dimensions, coupling slot feed etc.Feeding technique adapted in aperture coupled. This design is simulated using CST microwave studio software. The main aim of this project is to optimize the gain of...
