Abstract： Compared with other polarization types of antennas？ circular polarization antenna can receive incoming waves with arbitrary polarization， and its radiated electromagnetic waves can also be received by antennas with arbitrary polarization. Therefore， it is widely used in the fields of wechat communication， RFID and WLAN. In this paper， HFvSvS is used to study the design methods of several circularly polarized antennas？and a circularly polarized microstrip antenna with miniaturization， large bandwidth and high gain is designed by coupling feeding.

Key words：circular polarization， miniaturization， microstrip antenna

1引言

在隨著時代不斷發(fā)展，天線作為無線通信領(lǐng)域中的重要元器件之一，其應(yīng)用場景變得非常廣闊，其技術(shù)發(fā)展和實際應(yīng)用也十分成熟。（剩余3333字）
