Problems solved by technology

However, there are two main problems with the dipole antenna: because the dipole antenna is a balanced structure, and the coaxial line is an unbalanced structure, the power it bears is small; 3dB opening angle, so the gain is low
The above two problems greatly limit the application range of dipole antennas

Abstract

The invention relates to a full-band television transmitting antenna based on rhombic oscillators. Dipole group arrays are rhombic dipole group arrays which are formed by four pairs of rhombic dipoles through coaxial arrangement; a multi-section broadband adjustable power divider feed network is divided into a vertical part and a horizontal part, the horizontal part is parallel to a reflecting board, the external conductors of the vertical part and the horizontal part are connected by square copper blocks, and the square copper blocks are fixed on the reflecting board; the external conductor of the output end of the multi-section broadband adjustable power divider feed network is connected with the internal side strip of a strip-shaped parallel line, and the internal conductor stretches out to be connected with the external side strip of the strip-shaped parallel line; and one end of the a balun transmission line is connected with the center of the external side strip of the strip-shaped parallel line, and the other end is connected with the square copper blocks. A mode of parallel feeding of the rhombic dipole group arrays is adopted so that working bandwidth of which standing-wave ratio less than 1.2 is enabled to be more than 360MHz, and a full-band transmitting function is realized; and bearing power is high, manufacturing cost is low, and thus the full-band television transmitting antenna based on the rhombic oscillators is especially suitable for a decimetric wave band ground television transmitting system.

Description

technical field [0001] The invention relates to a full-band TV transmitting antenna, in particular to a rhombic vibrator horizontally polarized array antenna applied to 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 in most large and me...
