The radiation pattern of the omnidirectional antenna
An omnidirectional antenna, that is, shows uniform radiation at 360° on the horizontal pattern, which is commonly referred to as non-directional and shows a beam with a certain width on the vertical pattern. In general, the smaller the lobe width, the greater the gain.
Omnidirectional antennas are generally used in communication systems with short distances, large coverage areas, and low prices. The gain is generally below 9dB. The following figure shows the signal radiation pattern of the omnidirectional antenna:
Selection and installation of an omnidirectional antenna
If you need to meet multiple sites, and these sites are distributed in different directions of the AP, you need to use omnidirectional antennas; if they are concentrated in one direction, it is recommended to use directional antennas; in addition, consider whether the antenna joint form matches the AP and the antenna Whether the gain size and so on meet your needs;
For outdoor antennas, lightning protection equipment needs to be added between the antenna and the wireless AP; for directional antennas, pay attention to the direction that the front of the antenna faces the remote site; the antenna should be installed as high as possible, and the line of sight between the antenna and the site should be as high as possible.
The radiation pattern of an omnidirectional antenna
Monopole
1.1 Microstrip fed monopole.
The planar monopole antenna has a simple structure and a nearly omnidirectional radiation pattern. It is widely used in communications. The biggest difference between these antennae is the deformation of the ground.
The ground of a conventional antenna is often the size of the entire medium. The ground of the monopole is only half the size of the medium, and one side is changed to an ellipse and a triangle.
The ratio of the semi-long axis of the ellipse is 1.8. The monopole is also elliptical, and the ratio of the semi-long axis is 1.2. The whole antenna With microstrip feed, the ground width W, and the length h of the feed slot are the main parameters that affect the performance of the antenna.
1.2 Monopole antenna fed by a coplanar waveguide.
One of its characteristics is the use of coplanar waveguide feeding. Compared with traditional microstrip lines, coplanar waveguides have two major advantages: low-frequency offset characteristics and wide impedance bandwidth.
Another feature is that the radiating element uses hexagonal patches. Compared with other rectangles, squares, and triangles, the hexagonal shape also has the inherent advantages of broadband characteristics.
The entire antenna feed section opens holes on the upper and lower sides of the grounded coplanar waveguide to form a short circuit between the upper and lower layers, thereby preventing the generation of parasitic modes, and the number of holes can also change the input impedance of the antenna.
The ground under the hexagonal patch is removed, which can promote the radiation of the bottom wide side. Good matching can be achieved by adjusting the width of the feeder and the gaps on both sides of the feeder, which also makes it easy for the antenna to obtain impedance matching.
Dipole
Although monopoles and dipoles theoretically have omnidirectional radiation patterns, in fact, due to the influence of the feeder, the electric field on the vertical plane is down-tilted, which affects the radiation characteristics in the horizontal direction, so it is difficult to obtain the omnidirectional direction Figure.
The antenna is composed of dipoles. By reasonably arranging the isolation between the dipole radiating element and the feeder, the influence of the feeder is shielded, so that omnidirectional radiation is achieved in the horizontal direction.
The antenna adopts another dipole as the parasitic element to make the entire antenna It works in two frequency bands 0.9GHZ and 2.0GHZ, and the antenna gain is very high, and the two frequency bands reach 10dBi and 12dBi respectively.
The whole antenna structure is a metal tube in the middle. There are four dielectrics around the metal tube. Each medium has two dipoles with parasitic elements.
The length of the dipole is 137mm, the operating frequency is 0.9GHZ, and the length of the parasitic element. It is 47mm, the working frequency is 2.0GHZ, the center distance of two dipoles on the same substrate is 150mm, and the entire antenna is covered with a cylindrical radome with a diameter of 110mm. The feed part of the antenna uses a four-way splitter and balun.
