Abstract

The invention discloses a polarized antenna which comprises a first feed source used for transmitting a first feed source signal, a second feed source used for transmitting a second feed source signal, a first phase modulator used for being connected with the first feed source and converting the first feed source signal into a first signal or a second signal, a power divider used for being connected with the first phase modulator and the second feed source and converting the first signal and the second feed source signal into a first polarized wave, or converting the second signal and the second feed source signal into a second polarized wave, wherein the first polarized wave and the second polarized wave are different in phase, and a receiver used for being connected with the power divider and receiving the first polarized wave or the second polarized wave. In this way, the polarized antenna can adjust and output the first polarized wave or the second polarized wave in real time according to the position where the polarized antenna is located, so that polarization matching with the transmitting end is achieved, the receiving sensitivity is guaranteed, and performance loss is avoided. The invention also discloses electronic equipment.

Description

technical field [0001] The present application relates to the field of electronic equipment, in particular to a polarized antenna and electronic equipment. Background technique [0002] Electronic devices need to be equipped with polarized antennas to receive signals from transmitting base stations. For example, mobile phones are equipped with GNSS (Global Navigation Satellite System, Global Navigation Satellite System) frequency band antennas to receive radio waves from GNSS transmitting base stations to realize positioning and navigation functions. [0003] The polarized antenna is usually installed at a specific position of the electronic device. Taking the GNSS system as an example, the GNSS transmitting base station usually sends out right-handed circularly polarized radio waves, so the right-handed circularly polarized antenna needs to be installed on the receiving surface of the electronic device facing the transmitting end. To make the electronic equipment receive ri...
