Abstract

The invention discloses a pattern electronically-tunable linearly-polarized dipole antenna, which comprises four antenna units, a square PCB, a feed port, a metal grounding board, a dielectric board and an isolated capacitor, wherein the dielectric board is composed of four dielectric pieces; the four antenna units are located on the four end surfaces of the PCB respectively; and each antenna unit comprises six metal pieces with the identical structures, and the metal pieces are distributed in a center symmetry mode. The pattern electronically-tunable linearly-polarized dipole antenna is extremely applicable to a modern wireless communication system, and has the advantages that the structure is simple; the loss is low; the bandwidth is wide; the gains are high; the radiation efficiency is high; convenient switching among the four radiation directions can be achieved; and the like.

Description

[Technical Field] [0001] The invention relates to a microwave passive device, in particular to a directional pattern electrically adjustable linearly polarized dipole antenna. [Background technique] [0002] With the vigorous development of wireless communication, the antenna is an important part of the communication system, and its performance determines whether the system can work normally and whether various functions can run smoothly. In recent years, with the development of multiple mobile communication applications such as GSM, 3G, LTE, WiFi, WLAN, WiMAX, etc., this requires the antenna on the device to have a strong function of sending and receiving information. Under the condition of limited spectrum resources, high-speed, large-capacity information transmission and multi-service collaboration are realized; on the other hand, due to the rapid development of modern large-capacity, multi-functional integrated wireless communication systems, it is possible to use the same co...
