Abstract

The invention discloses a miniaturized conformal antenna. The interior of a metal cavity is used for installing an internal module. A flexible printed board and an outer surface of the metal cavity are installed in a conformal manner. Microstrip patch antennas are fixedly connected with the flexible printed board and are at one side of the flexible printed circuit board far away from the metal cavity, and the plurality of microstrip patch antennas enclose the flexible printed board. One end of a feed network is electrically connected with each microstrip patch antenna, the other end of the feed network passes into the metal cavity and is electrically connected with an internal module, and the feed network and a radiation surface of the flexible printed board are in an integrated coplanar design. Therefore, a sensor network node can effectively utilize a space structure, the influence of the internal module on the antenna radiation performance is reduced by using the shielding effect ofthe metal cavity, and the influence on the performance of a whole machine is reduced.

Description

technical field [0001] The invention relates to the technical field of antennas in wireless communication, in particular to a miniaturized conformal antenna. Background technique [0002] The miniaturized conformal antenna is applied to the nodes of the sensor network for the sprinkled spectrum monitoring. In order to meet the requirements of dispensability and concealment in the battlefield environment, the sensor network nodes must achieve a miniaturized design, and there are also strict restrictions on their weight and center of gravity. The miniaturization of the antenna is the key to the miniaturization of the whole node. [0003] According to the antenna design theory, the size of the antenna is related to the wavelength corresponding to the working frequency band. The traditional omnidirectional antenna is usually a three-dimensional symmetrical structure. wave action. At the same time, in order to meet the omnidirectional radiation characteristics, there should be...
