Dual Circular-Polarized Slot Antenna Design for Wireless MIMO System at 2.4 GHz

This work proposed a dual circular-polarized slot antenna for wireless local area network (WLAN) application at 2.4 GHz. The proposed design is simulated by using FR-4 as is substrates. In this work, three stages of antenna had been simulated in CST Microwave Studio. First two antenna, Design 1-A and Design 1-B is containing a single polarized antenna with different feedline port location. An X-shaped structure is located at the middle of the patch at angle of 42.5 degrees. Then, dual feedline port antenna, Design B1 are designed to create dual circular-polarized effect. The return loss S11 results at 2.4 GHz of Design 2-A antenna are - 21.511 dB and–28.48 dB for simulation results and measurement results, respectively. For axial ratio for Port 1 and Port 2 are 0.63 and 1.12, respectively. In the end, the simulation and measured antenna design are compared.
