Description
Summary:A new structure of microstrip Yagi antenna is proposed in this article in order to obtain a high gain and wide bandwidth. It is called Octagon Microstrip Yagi Antenna. The Octagon Microstrip Yagi Antenna has been simulated, optimized, constructed, and tested. According to simulated results, it appears that the simulated Octagon Microstrip Yagi Antenna has the ability to obtain 15.97% bandwidth and gain of 11.16 dB in a compact size of 70 mm × 75 mm. On the other hand, experimental results show that the fabricated Octagon Microstrip Yagi Antenna can achieve a gain of 11 dB with 13.8% bandwidth. It can be seen that there is a good agreement between simulation and measurement results. Hence, it gives evidence that the proposed antenna is capable of producing a high gain with a wide bandwidth in a smaller size as compared to the others.
