“…The multi-feed method can obtain better axial ratio characteristics, but the feed network is complex and large due to the application of multi-feed points. To notch up circular polarization through a single feed [8][9][10][11][12][13][14][15][16], it is necessary to feed in the orthogonal direction with a difference of 90 degrees to stimulate circular polarization. Due to the inductance effect on the surface of the patch, it is difficult to realize impedance matching and easy to produce machining errors.…”

A small ring antenna working at 2.45 GHz was designed in this paper, a small disk-coupled structure was applied to feed an inner-hole-biased ring patch, contributing to not only improving the impedance characteristics of the antenna but also reducing the size. The simulation results show that the designed patch area is only 70.7% of that of the traditional circular microstrip antenna on the premise of ensuring good bandwidth and gain performance; the −10 dB bandwidth of S 11 parameter is 62 MHz; the gain of the maximum direction is 7.11 dB; and the circular polarization of the antenna is also realized. This design has also been compared with several conventional designs. It is proved that the antenna has good comprehensive performance, and the antenna feed structure is simple, easy to process, very conducive to engineering applications. Finally, the feasibility of this technology was verified by contrasting the measured data with the simulation data.
