Antenna gain and gain consideration
In the actual application of wireless communication, in order to effectively improve the communication effect and reduce the input power of the antenna, the antenna will be made into various structures with radiation directionality to concentrate the radiation power, which leads to the concept of antenna gain.
Antenna gain refers to the degree to which an antenna concentrates the input radio frequency power. Obviously, the antenna gain has a great relationship with its pattern.
The narrower the main lobe and the smaller the side lobe, the higher the gain of the antenna. Antennas of different structures have very different patterns of patterns.
In the field of communication technology, like other parameters such as power and level, the antenna gain is also expressed by the simplified method of relative comparison and logarithm. The specific calculation method is to generate the same radiation field in a certain direction to a certain position.
When it is strong, take the logarithm of the ratio of the input power of the lossless ideal reference antenna to the input power of the antenna to be considered and multiply it by 10 (G=10lg (reference Pin/consideration Pin)), which is called the antenna at that point Directional gain.
Commonly used units to measure antenna gain are dBi and dBd. For dBi, the reference is an ideal point source antenna, that is, a point in the true sense as a reference for antenna gain comparison.
The radiation of an ideal point source antenna is omnidirectional, its pattern is an ideal sphere, and the electromagnetic wave radiation intensity of all points on the same sphere is the same; for dBd, the reference is an ideal dipole antenna.
Because the dipole antenna is directional, the two have a fixed constant difference of 2.15, 0dBd=2.15dBi.
It should be noted that the usual omnidirectional antenna is not a strict term.
The omnidirectional antenna should refer to the omnidirectional in three-dimensional space, but the engineering community often refers to the antenna with a circular pattern in a plane as omnidirectional An antenna, such as a whip antenna, has a circular main lobe in the radial direction, but still has an axial side lobe.
Common antenna gain: whip antenna 6-9dBi, GSM base station uses Yagi antenna 15-17dBi, a parabolic directional antenna can easily achieve 24dBi.
