A four-way antenna

Abstract

The invention discloses a four-directional antenna. The four-directional antenna comprises two microstrip antennae, two monopole antennae and a mounting base plate, wherein the two microstrip antennaeand the two monopole antennae are respectively fixed on the mounting base plate, and the two microstrip antennae are opposite in radiation directions; and the two monopole antennae are respectively fixed at the two sides of the two microstrip antennae. According to high-speed flight or operation characteristic of an existing carrier, the four-directional antenna disclosed by the invention adoptsa way that the microstrip antennae and the monopole antennae are combined, on the basis of keeping miniaturization and a conformal mode, the integrated design of an omnidirectional function and an orientating function of the antenna is realized by controlling phase difference of an antenna element, and better electrical properties can be kept in any direction in the horizontal plane.

Description

technical field

[0001] The present invention relates to the field of antenna research, in particular to a four-way antenna. Background technique

[0002] Under the development trend that the global industry requires electronic products to be "light, thin, short, and small", the antenna, as a necessary carrier device for communication, should have the advantages of miniaturization, light weight, and high performance. Microstrip antennas and monopole antennas are the two most common forms due to their simple structure, low profile, light weight, and easy conformality. As an electromagnetic wave generation and radiation device, the performance of the antenna is largely limited by the shape and size of the radiator. Usually, the directional characteristic of a single antenna is fixed, and how to realize the integrated design of directional function and omnidirectional function in a small size has become a big problem. In order to meet the antenna requirements in the current ap...
