Polarization Reconfigurable Patch Antenna for Wireless Power Transfer Related Applications
文献摘要：
A polarized reconfigurable patch antenna is proposed in this paper. The proposed antenna is a dual cross-polarized patch antenna with a programmable power divider. The programmable power divider consists of two branch line couplers (BLC) and a digital phase shifter. By adjusting the phase of the phase shifter, the power ratio of the power divider can be changed, and thus the feed power to the antenna input port can be changed to reconfigure the antenna polarization. The phase-controlled power divider and the cross dual-polarized antenna are de?signed, fabricated and tested, and then they are combined to realize the polarized reconfigurable antenna. By moving the phase of the phase shifter, the antenna polarization is reconfigured into vertical polarization (VP), horizontal polarization (HP), and circular polarization (CP). The test is conducted at the frequency of 915 MHz, which is widely used for simultaneous wireless information and power transfer (SWIPT) in radio-frequency identification (RFID) applications. The results demonstrate that when the antenna is configured as CP, the axial ratio of the antenna is less than 3 dB, and when the antenna is configured as HP or VP, the axial ratio of the antenna exceeds 20 dB. Finally, experiments are conducted to verify the influence of antenna polarization changes on wireless power transmitting. As expected, the reconfigured antenna polarization can help improve the power transmitting efficiency.
