| Popis: | This paper presents a design of a high gain cavity-backed circular patch antenna for X-band applications. By using substrate integrated waveguide (SIW) based cavity and feeding mechanism of a microstrip-SIW-transition based on a taper. The proposed antenna is investigated in terms of antenna performances including reflection coefficient, gain, and radiation pattern. Instead, using a conventional circular patch, a modified circular patch is employed to achieve a good matching and high gain. Moreover, the proposed antenna has been simulated by using CST Microwave Studio. Simulation results indicate that the circular patch antenna achieves a good gain of 7.2dB at X-band of 10 GHz center frequency, which shows that this antenna retains good radiation performance of conventional cavity backed antennas. |
