Problems solved by technology

However, these antennas cannot yet achieve a structure and size covering the entire digital TV frequency range of 470-860MHz, and can only emit horizontally polarized waves
These two problems lead to higher antenna production costs and limit the general applicability of the antenna

Abstract

The invention relates to a vertically polarized ground television transmitting antenna based on a disk oscillator. The vertically polarized ground television transmitting antenna comprises a disk dipole array, a multi-section broadband adjustable power divider feed network, an input connector, a reflecting plate, band shape parallel line feed structures, nylon pillars, a Balun feed structure, band shape parallel line feed connecting pieces and power divider feed network connecting pieces, wherein the disk dipole array is a vertically polarized antenna array which is formed by a plurality of disk dipoles. By improving the impedance bandwidth and the borne power of the array antenna, the vertically polarized ground television transmitting antenna can satisfy the operating requirement for a ground television broadcasting transmission system. The vertically polarized ground television transmitting antenna is provided with a working frequency band width, and has the advantages of being small in input standing-wave ratio, being large in borne power, being simple in processing, being convenient for debugging and being low in cost, and is suitable for the ground television broadcasting transmission system application of the decimeter wave band.

Description

technical field [0001] The invention relates to a TV transmitting antenna, in particular to a vertically polarized terrestrial TV transmitting antenna based on a disc vibrator suitable for a decimeter wave band terrestrial TV transmitting system. Background technique [0002] The antenna and its feeding equipment are the important links between receiving and transmitting equipment and space radio waves, and are important devices for converting the power of the transmitter into electromagnetic waves and propagating them to distant places. To build an ideal small TV switch, in addition to having a high-quality TV switch, there must also be a good transmitting and receiving antenna. Using high-quality antennas can effectively use the power of the transmitter and reduce the requirements on the receiver. With the continuous acceleration of global TV digitization and mobility, my country's digital TV has developed rapidly in recent years, and digital TV services have been opened ...
