Microstrip planer antenna array by proximity fed for complete S band applications

A naval single band antenna presented is a combination of four element patches, printed on a substrate, for 3.4 GHz frequency operation. The array of antenna uses the ground at the bottom of substrate, a patch at top of substrate fed with proximity coupling. This array has a very simple structure; with size of 50×50mmexcited by discrete port through proxy feeding, which is also having efficient radiator to contribute the resonance for antenna to cover the complete S-Band. It provides the impedance bandwidth of 1.72GHz and Gain of 7.39dB. This antenna is coupled with 50 ohm where modeled through the CST microwave studio antenna software, where it uses finite element method for designing the antenna. The proposed microstrip antenna shows the good impedance bandwidth matching, high gain, high radiation efficiency and high directivity. Results are precisely obtained and validation of model is also verified.
