Abstract

Provided are an ultra-wideband horizontally polarized omni-directional antenna and a construction method thereof. The method include the following steps: step 1, establishing a space rectangular coordinate system; step 2, constructing an upper arm of an Alford ring; step 3, constructing a lower arm of the Alford ring; and step 4, carrying out center coaxial feeding. At least three arc-shaped oscillators are provided. The radian of each oscillator is about 180 degrees, feeding is performed by two conductors, and the pairs of oscillators are not coplanar. Feeding is notified by the center, and the performance better than that of a printed form is obtained. The bandwidth is wider, reaching 62%, broadening above 20%. The gain is high, reaching 2.5-4.8 dBi and improving 1-2dB. The efficiency ishigher, increased by more than 10%. The power capacity increases by at least 100%. The cost is reduced by at least 50%. The method also has the characteristics that the idea is novel, the principle is clear, the method is universal and is easy to realize, the batch production is easy and so on. The scheme of the invention is a low-cost optimal scheme of an Alford ring antenna, and is also applicable to design and improvement of high gain horizontally polarized omni-directional array antennas, multi-frequency horizontally polarized omni-directional antennas and H / V dual polarized omni-directional antennas.

Description

technical field [0001] The invention relates to a wireless communication antenna device and technology, in particular to an ultra-wideband horizontally polarized omnidirectional antenna and a construction method. Background technique [0002] Omnidirectional antenna is an important antenna type in the field of wireless communication. For a long time, most omnidirectional antennas invented by people are vertically polarized, but the design of horizontally polarized omnidirectional antennas is much more difficult. However, the application requirements of horizontally polarized omnidirectional antennas are also very strong and extensive, such as forming H / V orthogonal dual-polarized omnidirectional MIMO antennas with vertically polarized omnidirectional antennas to improve the capacity of communication systems. So far, the horizontally polarized horizontal omnidirectional antennas that have been invented are almost all based on the loop antenna theory, that is, the electric sm...
