Dual Band 2.4G 4G Whip Stubby 60MM OMNI External Antenna With Straight N Female Connector

What Is The Function Of The Antenna?

Antenna is a kind of converter, which transforms the guided wave propagating on the transmission line into the electromagnetic wave propagating in the unbounded medium (usually between free space BAI), or vice versa. In radio equipment, a component used to transmit or receive electromagnetic waves. Radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, radio astronomy and other engineering systems, which use electromagnetic waves to transmit information, all rely on the antenna to work. In addition, in the aspect of energy transmission by electromagnetic wave, the energy radiation of non signal also needs antenna. Generally, antennas are reversible, that is, the same antenna can be used as both transmitting antenna and receiving antenna. The basic characteristic parameters of the same antenna are the same. This is the reciprocity theorem of antennas.

Dual Band Antenna Electrical Characteristics:

When high frequency current is applied to the conductor, electric field and magnetic field will be generated in the surrounding space. According to the spatial distribution characteristics of electromagnetic field, it can be divided into near region, middle region and far region. Let R be the distance between a point in space and the conductor, and the region of time is called the near region. The electromagnetic field in this region is closely related to the current and voltage in the conductor. In this region, the electromagnetic field can leave the conductor and propagate into space, and its change will lag behind the current and voltage on the conductor for a period of time. At this time, the electromagnetic wave propagated is no longer directly related to the current and voltage on the conductor, and the electromagnetic field in this region is called radiation field.

It must be pointed out that when the length L of the wire is much less than the wavelength λ, the radiation is very weak; when the length L of the wire is increased to be comparable with the wavelength, the current on the wire will increase greatly, so a strong radiation can be formed.
