Abstract

Microstrip antennas are the most common antennas widely implemented in different communication systems due to its small size, low profile and conformity to planar and non-planar surfaces. In this research work, the design and simulation of an innovative single element insetfed Rectangular Microstrip Patch Antenna (RMPA) for X-band application is presented. The proposed design used an operating frequency of 10 GHz, a Rogers RO4350 (tw) substrate with dielectric constant of 3.66, and a substrate height of 31 ml. The antenna performance characteristics such as return loss, bandwidth, VSWR, gain, directivity, beam width and radiation efficiency were obtained in the simulation. The simulation results showed that the designed antenna resonated at 10 GHz, with a return loss of -19.61 dB, bandwidth of 226.2MHz, VSWR of 1.82, gain of 6.58 dBi, directivity of 6.83 dBi, a wider beam width of 115.2o, and an antenna efficiency of 94.2%. The novel designed antenna can be embedded in wireless devices for commercial WLAN and WiMAX applications and also for onboarding on radar and satellite wireless communication systems for various surveillance and communication purposes.
