This paper presents, the design, and the feeding techniques of a rectangular microstrip antenna operates at 2.45 GHz ISM band. There are various feeding techniques for patch antenna. These techniques are classified into two categories, which are contacting and non-contacting. In the contacting method, the antenna can directly feed with RF power using the contacting element as coaxial plane feed or a microstrip line. Contrarily, non-contacting techniques, the electromagnetic field coupling is done to transfer power between the microstrip line and the radiating patch. The most used non-contacting techniques are Aperture and Proximity Coupled Feed. The proposed rectangular microstrip antenna is designed based on the transmission line method. And it is optimized with the Method of Moment. A performance comparison between the different feeding techniques was made based on the reflection coefficient, gain and bandwidth results.
