Trident Feed High Gain Microstrip Patch Antenna with Comparative study of Different Feed Techniques
In this paper, a trident shaped feed line with microstrip patch is proposed to achieve a high gain. The designed antenna has a total size of 54x49mm2 and resonates at 2.45GHz with 4.01dB gain. Trident shape feed line provides high gain with good return loss. The antenna is simulated in HFSS and CST Microwave Studio. Simulation and measurement results have good agreement. Microstrip patch antenna with direct feed, quarter-wave transformer feed, inset feed and Trident feed are compared in terms of radiation pattern, gain and size.
