Problems solved by technology

However, the main disadvantages of patch antennas are narrow bandwidth and low power consumption. The bandwidth of a typical patch antenna with a VSWR of less than 1.1 is only on the order of a few tenths of a percent, and the f

Abstract

The invention relates to an E-type patch based horizontally-polarized digital television transmitting antenna array. The transmitting antenna array comprises a horizontally-polarized antenna unit, an equivalent-power-division in-phase feed network, a patch connector and an input connector; the horizontally-polarized antenna unit is formed by two laminated patch radiation units in a flushed in-phase arrangement; the laminated patch radiation unit comprises a rectangular parasitic patch top layer, a rectangular parasitic patch second layer, an E-type patch and a floor plate; the equivalent-power-division in-phase feed network is positioned between the E-type patch and the floor plate, and connected with the E-type patch through the patch connector; and an outer conductor of the input connector is fixed in the floor plate while the inner conductor of the input connector penetrates through the floor plate to be connected with the equivalent-power-division in-phase feed network. By adoption of the laminated structure and the E-type patch, the impendence bandwidth and the bearing power of the antenna are improved so as to satisfy the operating requirements of ground television broadcasting transmitting systems; and the E-type patch based horizontally-polarized digital television transmitting antenna array has the characteristics of wide working frequency bandwidth, high gain, low standing-wave ratio, high bearing power, simple process, convenient debugging and the like.

Description

technical field [0001] The invention relates to an antenna for a terrestrial digital television transmission system, in particular to a horizontally polarized array antenna based on an E-shaped patch suitable for a terrestrial television transmission system in the decimeter wave band. Background technique [0002] The antenna is an indispensable and important front-end device for any radio system, and its performance directly affects the overall performance of the radio system. With the development of radio technology, many communication devices will be eliminated, and their functions will be replaced by various software, but the function of the antenna cannot be realized by software. Therefore, even in the era of software radio, the antenna is indispensable. Use a high-quality antenna to build an ideal small TV switch. In addition to the high-quality TV switch, a good transmitting and receiving antenna is also very important. It can effectively use the power of the transmit...
