Abstract

Microwave antennas play a significant role in current wireless communication systems and are key components for converting electromagnetic waves into electrical signals. The performance of the antenna directly affects the distance and quality of the signal transmission. However, antennas still face problems such as high energy consumption, low precision, great integration difficulty, and difficulty in coping with complex environmental conditions that change in real time. This experiment is based on the multi-level simulation optimization technology of HFSS to conduct parametric modeling of circular antennas and optimize the model parameters. Compared with the traditional side-fed circular microstrip patch antenna, this microstrip antenna innovatively adds a groove in the middle of the circular patch. This structure can simultaneously excite the TM11 and TM21 modes, thereby increasing the bandwidth. By optimizing the model parameters, the final frequency band of the antenna can be around 6.6GHz. This project innovatively transformed the single antenna structure into an array form. The final frequency band range can reach 6.36 to 7.04GHz, with a peak gain of 7.5dBi. This scheme provides a simple simulation method for the future microwave antenna engineering.
