Abstract: Microstrip patches radiate from the currents induced on the surface of the patch because of the electromagnetic cavity with significant resonant frequencies formed between patch and ground plane according to the frequencies applied with different feeding techniques. This paper presents the design and simulation of a T-shaped Dual band Microstrip patch antenna with operating frequencies 5.40GHz, and 6.60GHz for C-Band applications. The T-shape provides Dual band characteristics with good bandwidth which is required in wireless devices with significant design characteristics and can be easily mounted on air craft, space craft, satellites, missiles etc., An Edge-Fed microstrip with substrate FR4epoxy having dielectric constant 4.4 and substrate heights of 6.5mm, 4.56 mm, 3.048mm, and 1.524mm are designed and analyzed with different parameters like VSWR, Gain, Peak directivity, Return losses, Bandwidth, Radiation efficiency, FBR etc,. This antenna design is an improvement from previous research and it is simulated using HFSS (High Frequency Structure Simulator) version 13.0 software.
