Application system of ultra-wideband composite antenna

Abstract

The invention discloses an application system of an ultra-wideband composite antenna. The system comprises a mounting bottom plate, a rotary table and an antenna cover. The rotary table is fixedly mounted on the mounting bottom plate. A fixed supporting column is arranged on the rotary table. A discone antenna is mounted on the fixed supporting column; a parabolic antenna is arranged above the discone antenna. A mounting base is fixedly connected to the top end of the fixed supporting column. A U-shaped installation groove is formed in the installation base, a driven rotating shaft is arrangedin the U-shaped installation groove, a connecting supporting column is fixedly installed on one side of the parabolic antenna, the connecting supporting column is fixedly connected with the driven rotating shaft through an installation shaft sleeve, and a driving rotating shaft is arranged at the end, close to the rotating table, of the fixed supporting column. Through combination of the parabolic antenna and the discone antenna, ultra-wide frequency band coverage can be met, and the whole system is reasonable in structure, small in size, light in weight and beneficial to installation and use. The antenna is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an application system of an ultra-wideband composite antenna. Background technique [0002] An antenna (antenna) is a transformer that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. A component used in radio equipment to transmit or receive electromagnetic waves. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, which use electromagnetic waves to transmit information, rely on antennas to work. In addition, in terms of transmitting energy with electromagnetic waves, non-signal energy radiation also requires antennas. General antennas are reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna. In modern electroni...
