The Antena Omnidirectional is also called a non-directional antenna. The representative of this antenna is the most common vertical antenna, which we call "miaozi" and "stick". It shows 360 ° uniform radiation in the horizontal pattern, that is, it is usually said that it has no directivity. In the vertical pattern, it shows a beam with a certain width. Generally, the smaller the lobe width, the greater the gain. Best omnidirectional antenna is generally used in the mobile communication system for the station type of suburban county and large area system, with a large coverage.
Array omnidirectional antenna
It is difficult for general element antenna to form omnidirectional radiation, so we can consider to form an array to make the array antenna form omnidirectional pattern. Moreover, the gain of a single antenna is generally limited. By forming an array, the gain can be improved to meet the requirements of omnidirectional high gain that we want to design.
Microstrip omnidirectional antenna
Microstrip antenna because of its simple structure, low processing cost, light weight, and many other advantages, become a key technology in the field of antenna, as a result, various performance of microstrip antenna are studied, the omni-directional sex has become a trend in the development of microstrip antenna, such as the use of microstrip transmission line for cross feed can realize omnidirectional radiation properties of the microstrip antenna.
A multi-point excited linear array antenna, the antenna is composed of a number of λ /2 microstrip segments connected in stages. The floor of the microstrip segment and the guide band are placed alternately on both sides of the dielectric substrate, and the floor width of the microstrip is varied. The purpose of phase inversion is achieved by cross connection.
In addition to the transmission mode, there is also a radiation mode formed by the discontinuity of the cross connection points. The wave is transmitted along the conduction band and the inner surface of the floor, and the radiation is controlled by the width of the floor, which is limited to about λ /4 in order to obtain good omnidirectional performance.
In order to make the antenna achieve good radiation efficiency, the impedance matching can also be carried out, and the rectangular patch is added to each band to improve the matching by increasing the reactance component.
