Directional antenna with slide tuning unit

Abstract

The invention discloses a directional antenna with a slide tuning unit. The directional antenna comprises a metal reflection floor (1) and a metal plate radiation unit (2) arranged on the metal reflection floor (1); the metal reflection floor (1) is a rectangular metal plate of which one end is turned into a right-angle side; one end of the metal plate radiation unit (2) is partially turned into a right-angle side, and the other end of the metal plate radiation unit (2) is provided with two symmetrical sloping sides; and on the turned bottom edge of the metal reflection floor, a sliding metal tuning unit (3) is arranged on lateral front of the metal radiation unit of the antenna, and by regulating the position of the metal tuning unit (3), an aim of widening the frequency band to tune input impedence property of the antenna is fulfilled. The antenna performance is convenient to tune, and the wide bandwidth can be effectively acquired; and the directional antenna is simple in structure, convenient to implement and low in cost and has high electrical and mechanical properties.

Description

technical field [0001] The invention relates to a directional antenna with a sliding tuning unit, and belongs to the technical field of antennas for indoor distribution systems of mobile communications. Background technique [0002] With the rapid increase of mobile users and more and more high-rise buildings in cities, the traffic density and coverage requirements are also rising. These buildings are large in scale and of good quality, and have a strong shielding effect on mobile phone signals. In the environment of low floors of large buildings, underground shopping malls, underground parking lots, etc., the mobile communication signal is weak, and the mobile phone cannot be used normally, forming a blind area and shadow area of ​​mobile communication; on the middle floor, due to the overlapping of signals from different surrounding base stations, The ping-pong effect is generated, the mobile phone is switched frequently, and even the call is dropped, which seriously affe...
