Abstract

The invention relates to the field of double-frequency antennas, particularly to a double-frequency omnidirectional dipole antenna, and solves the problems of double-frequency bandwidth and out-of-roundness and efficiency of an omnidirectional directional diagram of an antenna horizontal plane in the prior art. The antenna comprises a microwave dielectric substrate, which comprises an edge gap anda feed gap and is of a bilateral symmetry structure, wherein the left and right planes are divided into fixed area areas, metal patches are symmetrically arranged on the left and right planes, the antenna has a high-frequency-band working frequency band and a low-frequency-band working frequency band, the absolute value of S11 of the low frequency band is smaller than -10 dB, the impedance bandwidth is 4.1%, namely 2.4 GHz to 2.5 GHz, the absolute value of S11 of the high-frequency band is smaller than -10dB, and the impedance bandwidth is 18%, namely 5GHz-6GHz. The dual-frequency omnidirectional dipole antenna disclosed by the invention is in horizontal omnidirectional radiation, the dual-frequency bandwidth and the out-of-roundness and efficiency of an omnidirectional directional diagram of the horizontal plane of the antenna are effectively improved, the structure is simple, and the production and maintenance costs are reduced.

Description

technical field [0001] The invention relates to the field of dual-frequency antennas, in particular to a dual-frequency omnidirectional dipole antenna. Background technique [0002] The antenna design and antenna structure in the prior art generally depend on the experience of designers, which not only limits the scope of design, but also limits the accuracy of design. [0003] The antenna structure is limited by the structural space of the product, and is generally electrically small in size, making it difficult to design. The optimization performance is limited and limited by the solution space. [0004] There is an urgent need for a novel antenna that can solve the above problems. Contents of the invention [0005] The invention proposes a dual-frequency omnidirectional dipole antenna, which solves the problems of the dual-frequency bandwidth and the non-circularity and efficiency of the omnidirectional pattern of the antenna horizontal plane in the prior art. [000...
