| description | The invention provides a low-profile UHF antenna which comprises a dual-feeding-point circular polarized microstrip antenna unit, a first feeding probe and a second feed probe respectively connected with the two feeding points of the dual-feeding-point circular polarized microstrip antenna unit, two high-frequency sockets respectively and electrically connecting the first feeding probe and the second feed probe, and a four-port power-splitting phase-shift network arranged under the dual-feeding-point circular polarized microstrip antenna unit, wherein the first port and the second port of the four-port power-splitting phase-shift network are connected with the electric connecting ends of the high-frequency socket through the first feeding probe and the second feed probe, the third port of the four-port power-splitting phase-shift network outputs a left-turning circular polarized signal in responding to that received signal phase of the first portion is 90 degrees ahead that of the second port, and the fourth port of the four-port power-splitting phase-shift network outputs a right-turning circular polarized signals in responding to that received signal phase of the first portion is 90 degrees lagged behind that of the second port. The installation height of the antenna is low, and structure of the antenna is compact. |
