Miniaturization of Microstrip Antenna Using Techniques of Meandering, Loading, and Bending Slots

One of the existing challenges while realizing miniaturization of the antenna is ensuring that the performance of the antenna without any negative effect has become the main focus of many researchers and pose challenges towards microstrip antenna research. In this paper, we focus on the study of miniaturization of microstrip antennas by designing miniaturized antennas, and carry out modeling and simulation. On basis of existing theory, the proposed method introduces the miniaturization technology of three mainstream microstrip antennas, namely meandering, loading, and bending slots. The electromagnetic simulation software HFSS is used to analyze the influence of the parameters of the three technologies on the antenna performance, and respectively propose a miniaturization scheme of the microstrip antenna.
