Abstract

The invention provides an omnidirectional antenna array comprising a first biconical antenna unit, a second biconical antenna unit, and feed networks. The biconical antenna unit is used for receiving or transmitting a first high-frequency signal; the second biconical antenna unit stacked at the first biconical antenna unit is used for receiving or transmitting a second high-frequency signal having the same amplitude and phase as the first high-frequency signal; and the feed networks embedded in the first biconical antenna unit and the second biconical antenna unit are used for distributing high-frequency signals into a first high-frequency signal and a second high-frequency signal and transmitting the first high-frequency signal and the second high-frequency signal out or synthesizing the high-frequency signal and the second high-frequency signal into a high-frequency signal and receiving the high-frequency signal. The omnidirectional antenna array is applied to a Ka band or a higher band and a horizontal omnidirectional gain of over 10dBi is obtained.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to an omnidirectional antenna, specifically an omnidirectional antenna array. Background technique [0002] Omnidirectional antennas show 360-degree uniform radiation on the horizontal pattern, which is commonly referred to as non-directional. Since omnidirectional antennas can cover a large range, they are widely used in the communication field. Common omnidirectional antennas include dipole antennas, monopole antennas, biconical antennas, monoconical antennas, and loop antennas. However, the low gain of existing omnidirectional antennas cannot meet certain specific requirements. In fact, there is no single omnidirectional antenna with a gain of 10 dBi in the prior art. [0003] In order to make the gain more than 10dBi, people use an omnidirectional antenna array instead of a single omnidirectional antenna. The most commonly used antenna array is a collinear antenna arr...
