Multi-band support antenna

Abstract

The invention discloses a multi-band support antenna. The antenna comprises an antenna shell and an antenna mainboard, the surface of the antenna mainboard is fixedly connected with a limiting rubberhead, the surface of the limiting rubber head is provided with a groove, the surface of the groove is sleeved with a metal elastic piece, the left side of the bottom of the inner wall of the antenna shell is fixedly connected with a fixed box, the left side of the inner wall of the fixed box is fixedly connected with a reset spring, the right end of the reset spring is fixedly connected with a sliding plate, the top and the bottom of the sliding plate are slidably connected with the top and the bottom of the inner wall of the fixed box correspondingly, and the middle of the right side of the sliding plate is fixedly connected with a moving block. According to the multi-band support antenna, the antenna mainboard can be placed into a fixed container to work, so that the influence of severeweather elements such as rain, snow, wind and dust outside is avoided, the service life of the multi-band support antenna is greatly prolonged, later rapid maintenance is facilitated, and accurate operation of workers is facilitated.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a multi-band bracket antenna. Background technique [0002] An antenna is a transformer that transforms 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. Generally, antennas are reversible, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna. The basic characteristic parameters of the same antenna...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a multi-band bracket antenna, which solves the problem of external antennas, long-term exposure to complex external natural weather such as rain, snow, wind and dust, the external antenna aging speed is fast, the product life cycle is short, and The grounding point of the traditional antenna is unstable, which leads to the low stability of the overall use of the antenna. In addition, the circuit board of the traditional antenna is not easy to replace after damage, and the disassembly and assembly are very cumbersome.
