【 摘 要 】

With the rapid development of science and technology, it is an inevitable trend for wireless communication systems to work on the same platform in different frequency bands. Reconfigurable antenna realizes the reconfiguration of parameters such as resonant frequency, polarization mode and radiation direction. The function of traditional multi-antennas can be realized by a single antenna. This paper presents a frequency reconfigurable antenna, which is especially suitable for multi-band and single-band hopping network communication systems. The simulation results show that the bias network has little effect on the antenna performance. In this paper, a polarization reconfigurable clover antenna fed by coplanar waveguide is proposed, which can realize switching function between left-handed circular polarization and right-handed circular polarization.
