First, the 4G antenna Antenna: (antenna) is the high-frequency current or waveguide way into the electromagnetic waves and the direction of the law to launch out or from the inevitable direction of electromagnetic waves reduced to a high-frequency current of a device.

2, according to the job frequency band classification: can be divided into short-wave antenna, ultrashort wave antenna, microwave antenna, etc .; 3) according to the direction of the antenna, etc., can be divided into communication antenna, TV antenna, radar antenna, etc .; 2) Classification: can be divided into omnidirectional antenna, directional antenna, etc .; 4) by the shape classification; can be divided into linear antenna, surface antenna and so on.

Third, the omnidirectional antenna, that is, in the horizontal direction of the show for 360 ° uniform radiation, that is, often said that no direction, in the straight pattern on the performance of a certain width of the beam, under normal circumstances lobe width The smaller the gain, the greater the gain.

Fourth, the directional antenna, in the horizontal direction of the performance of the scale of the scale of radiation, that is, what is often said that the direction of the straight in the straight map on the performance of a certain width of the beam, with the same antenna, The smaller the width, the greater the gain.
