Design and Optimization of a Dual-Circular Element Antenna for High Frequency Application

There is a growing demand for antennas with high efficiency, compact design and low return loss while operating at high frequencies in modern wireless communication systems Current antenna designs face many challenges in optimizing performance to be achieved in these dimensions due to material limitations and complex geometries The paper proposes a new smart antenna design using Perfect Electric Conductor (PEC) materials to overcome these issues. The antenna incorporates dual circular slots in the rectangular PEC substrate, aimed at improving impedance matching, reducing power losses, and increasing radiation efficiency Simulated in CST Microwave Studio, the antenna is efficient at microwave frequency range, in consequence Featuring significant improvements in gain, bandwidth and restoration loss this system offers a robust solution to the challenges encountered in wireless power transmission and high- frequency communications systems,. and provides a compact and efficient alternative to the conventional antenna system
