In this study, we used the IE3D programme to build and analyse a Circular Microstrip Patch (CMP) antenna intended for microwave communication and its purposes. The principal goal of this project is in the direction of evaluate the proposal of a CMP antenna using a microstrip feed line at various microwave band frequencies in order to make it functional for the intended use. As a result, we employed PTFE substrate material with a 4.4 dielectric constant and a 1.6 mm substrate height. After examining the design, we discovered that this approach is very dependable and efficient for the intended applications. As a result, we were able to achieve good return loss of − 22.44 dB and enhanced bandwidth of more than 10 GHz with lower range of VSWR. The proposed (or) suggested antenna is also applicable for body mount antenna. In the proposed antenna, we are using the feeding methods which are combination of transmission line feeding and co axial feeding. When coaxial feeding is active and transmission line feeding acts as a parasitic element, the antenna resonates at 9.44 GHz with − 16.71 dB return loss, whereas when both feed are active, the proposed antenna is useful for UWB antenna with more than 10 GHz bandwidth and good return loss. The suggested antenna is applicable for ultra-wide band application when both ports are active, and antenna is applicable for X-band application when coaxial feed are active.
