Problems solved by technology
[0003] Most of the existing antennas on the market work in single polarization mode. The two polarization modes of the antenna can be set separately by installing the antenna horizontally or vertically, but only one polarization mode can be used at the same time, resulting in that one antenna cannot transmit and receive two modes at the same time. Polarized signal, which reduces the transceiver performance of the device

The invention discloses a vertical and horizontal dual-polarized television antenna, comprising a mounting plate on which a first antenna oscillator and a second antenna oscillator which are symmetrically arranged around a central point and a third antenna oscillator and a fourth antenna oscillator which are symmetrically arranged around the central point are arranged, a connecting line between the first antenna oscillator and the second antenna oscillator is perpendicular to a connecting line between the third antenna oscillator and the fourth antenna oscillator. The antenna comprises a PCB which is provided with a first connection point connected with the first antenna oscillator, a second connection point connected with the second antenna oscillator, a third connection point connected with the third antenna oscillator and a fourth connection point connected with the fourth antenna oscillator, and signals are output through a single coaxial cable or a double coaxial cable; by adopting a design mode that four antenna oscillators are divided into two groups of resonance, the antenna can be placed in any direction, and can achieve the same efficiency when receiving vertical polarization and horizontal polarization signals without polarization loss.
Description
technical field [0001] The invention relates to the field, in particular to a vertical and horizontal dual-polarization television antenna. Background technique [0002] The antenna vibrator sends the received weak electromagnetic waves in the air to the transceiver equipment for processing through the coaxial cable. Signal transmission is divided into vertical polarization and horizontal polarization, and the transmitting and receiving antenna is also divided into vertical polarization and horizontal polarization. Only when the polarization of the signal and the antenna are consistent can the efficiency of receiving the signal be maximized. [0003] Most of the existing antennas on the market work in single polarization mode. The two polarization modes of the antenna can be set separately by installing the antenna horizontally or vertically, but only one polarization mode can be used at the same time, resulting in that one antenna cannot transmit and receive two modes at th...
