Abstract

The invention relates to a dual-frequency and dual-polarization broadcast television transmitting antenna. The antenna is characterized in that a vertical polarization frequency modulation double dipole plate antenna and a horizontal polarization metric wave four dipole plate antenna which take a reflecting plate as a carrier to form an element plate antenna in an array antenna, the element plate antenna forms a double-layer and four-surface, a four-layer and four-surface, a six-layer and four-surface or an eight-layer and four-surface antenna array on a transmitter tower, and by adopting constant amplitude in phase feeding or rotating field feeding, the structures of antennas on an identical reflecting plate, and an internal equilibrium conversion device and a wave trap are optimized, thus the available isolation between the two antennas is realized. The antenna overcomes the problem that the traditional frequency modulation double dipole plate antenna and the metric wave four dipole plate antenna can not share one reflecting plate, greatly reduces the occupied space of the antenna on the transmitter tower, and has the advantages of unique design, reasonable antenna structure, simpleness, practicality, convenient combination, light weight, excellent and stable index, and convenient mass production.

Description

technical field [0001] The invention belongs to radio and television wireless transmitting antennas, and relates to a novel antenna in which a FM double-dipole plate antenna and a meter-wave quadruple-dipole plate antenna share one reflector, in particular to a dual-frequency and dual-polarization radio and television transmitting antenna. Background technique [0002] At present, it is common for domestic FM double-dipole plate antennas and meter-wave quadruple-dipole plate antennas to share towers. They each form an antenna array on the transmission tower. Due to the use of independent reflectors, the antenna arrays each occupy a large space on the tower. With the rapid development of China's information technology and the unprecedented prosperity of the information industry market, the phenomenon of multiple antennas sharing towers on the transmission towers abounds, and the available space on the towers is getting less and less.
