Abstract

The invention discloses a communication antenna and a mounting and detaching method therefor. The communication antenna comprises a mounting base, a back cavity, a microstrip antenna and a radio frequency cable assembly; the mounting base is used for being pasted and fixed in the position of an internal window of a carrying platform, and the back cavity is fixed in the mounting base; one end of a core wire of the radio frequency cable assembly is mounted on a conductive bottom plate of the back cavity while the other end of the core wire is connected with a feed point of the microstrip antenna; a radio frequency cable shielding layer is grounded; a microstrip antenna is fixedly connected with the conductive bottom plate of the back cavity; and the height between the conductive bottom plate and the mounting base is adjustable. The communication antenna provided by the invention is free of transformation on the mounting platform, capable of being mounted and detached rapidly and high in imperceptibility; the communication antenna can be rapidly mounted in a traceless manner when a temporary task is executed; the original shape can be recovered rapidly in retraction, so that high imperceptibility is realized; and meanwhile, electromagnetic interference to other electronic equipment in the platform can be avoided in operation, and electromagnetic compatibility to the equipment is also achieved.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a communication antenna and its installation and removal method. Background technique [0002] At present, many delivery platforms have their own communication equipment, but the signal channels of these communication equipment are public and can be easily cracked and monitored. Therefore, it is sometimes necessary to install communication equipment in other frequency bands. In order to make the communication more concealed and confidential, it is sometimes necessary to conceal the additional antenna, which cannot be easily distinguished from the appearance. [0003] There are three ways to install concealed antennas: one is to transform the existing antenna equipment to increase its compatibility; the other is to specially design the antenna conformal to the shape; the third is to transfer the antenna to the inside of the platform. The first method needs to rede...
