Abstract

The invention discloses a low profile antenna with adjustable radiation characteristics. The invention includes a radiator metal layer, a periodic mechanism, an antenna feeding mechanism and an adjustment drive mechanism; the radiator metal layer, the periodic mechanism and the adjustment drive mechanism are stacked sequentially from top to bottom, and the radiator metal layer and the periodic mechanism are arranged at intervals , the antenna feeding mechanism is arranged below the adjusting drive mechanism or between the radiator metal layer and the periodic mechanism, the antenna feeding mechanism is connected to the radiator metal layer, and the radiator metal layer is fed through the antenna feeding mechanism. The height of the metal cylinder is adjusted individually or as a whole by the driving mechanism, which changes the resonant frequency and working amplitude and phase of the metal radiation unit. The invention changes the working frequency and radiation pattern of the low-profile antenna by adjusting the height of the metal columnar body; the mechanism is simple and flexible, and can carry high-power antenna signals, and is applicable to 5G base stations that require high power and adjustable antenna parameters antenna design.

Description

technical field [0001] The invention belongs to the field of electronic technology, and relates to an adjustable low-profile antenna, in particular to a low-profile antenna whose frequency and beam direction in a communication frequency band are continuously adjustable. Background technique [0002] With the development of wireless communication, the importance of low-profile antennas and reconfigurable antennas is more significant. Due to its low profile, low cost and ease of design, patch antennas have gradually attracted people's attention. By adding adjustable elements to the patch antenna mechanism, an adjustable antenna can be realized. The adjustable antenna has been developed because of its characteristic of realizing multiple functions on one antenna. [0003] In addition to the design of the radiator mechanism, some designs that improve the performance of the antenna through the ground plane mechanism have gradually emerged. Many periodic mechanisms are used in th...
