Abstract

The invention discloses a full-band double-layer trapezoidal digital television transmitting antenna, which includes an antenna unit, a connector, and a reflection plate. The connector supplies powerto the antenna unit. The connector and the antenna unit are fixed to the reflection plate. The antenna unit includes two groups of double-layer trapezoidal dipole units, adjustable insulating screws,a first feeding metal strip, a second feeding metal strip, a stepped linear impedance converter, a balun structure and a support structure. The stepped linear impedance converter includes a vertical linear impedance converter, a horizontal stepped impedance converter, and a compensating complex impedance connector which are connected successively. The full-band double-layer trapezoidal digital television transmitting antenna can cover the full frequency band of a digital television, can withstand large power, has a low voltage standing wave ratio, low cost, and high gain, and is easy to debug.

Description

technical field [0001] The invention relates to a digital TV transmitting antenna, in particular to a full-band double-layer trapezoidal digital TV transmitting antenna. Background technique [0002] Terrestrial digital television broadcasting, as a basic means and an important way to provide broadcasting and television public services, has been regarded by developed countries as a "strategic technology" of great significance to the information development of human society. Compared with traditional analog TV, digital TV has the advantages of high signal transmission quality, high utilization rate of spectrum resources, and high utilization rate of equipment, and can provide people with more interactive TV services. Among them, the transmitting antenna, as an important part of the digital radio and television system, plays a decisive role in the propagation ability of radio and television signals. A high-quality antenna can broaden the signal coverage and improve the qualit...
