Problems solved by technology

Mounting multiple antennas in a limited space will inevitably cause crowding between different types of antennas, deteriorating the electromagnetic compatibility and radar cross-section of the system, resulting in a downward tilt of the radiation pattern, and will also increase with the increase in operating frequency And further deterioration, the radiation pattern is no longer symmetrical about the horizontal plane, and the gain of the horizontal plane is greatly reduced

Abstract

The invention provides an omnidirectional antenna. The omnidirectional antenna comprises a first cone and a second cone, the first cone comprises a first circular truncated cone part and a first cylinder, and the second cone comprises a second circular truncated cone part and a second cylinder, wherein the top of the first circular truncated cone part and the top of the second circular truncated cone part are close to each other and are oppositely arranged, the bottom of the first circular truncated cone part is connected with the first cylinder, and the bottom of the second circular truncated cone part is connected with the second cylinder. The antenna has a stable horizontal omnidirectional radiation characteristic, and is simple in structure and easy to implement.

Description

【Technical field】 [0001] The invention relates to the technical field of communications, in particular to an omnidirectional antenna and a radome. 【Background technique】 [0002] Antennas play an extremely important role as the front end of modern wireless systems such as radar, communication, navigation, and remote sensing. With the development of modern information technology, people have put forward higher requirements on the performance of the antenna, hoping that it will have excellent performance in terms of electrical performance such as pattern, gain, and working bandwidth. At the same time, with the continuous development and innovation of integrated technology and miniaturization technology, higher requirements are put forward for the miniaturization and portability of the antenna structure. In some narrow application scenarios, in order to realize the transmission and reception of electromagnetic waves in different frequency bands, there are often scenes with mul...
