Abstract

The invention discloses a coupler capable of simultaneously providing frequency reconfiguration and power dividing ratio reconfiguration. The reconfigurable coupler comprises a basically circular patch, wherein the angles among four ports are 90 degrees, so that the direct connecting, coupling and isolating effects of the coupler can be achieved. The circular patch is considered to be formed by four different sectors; and when the radiuses of the sectors are different in value, the working frequency and the power dividing ratio of the coupler are changed. The coupler is designed at a commonly used wireless communication frequency band, can achieve a multi-frequency response, provides any power dividing ratio and simultaneously has relatively good coupling degree and isolating degree, so that the coupler can be widely applied to the field of communication with a multi-standard or multi-system requirement.

Description

technical field [0001] The present invention relates to a coupler used in the field of wireless communication, especially a coupler that can provide reconfigurable frequency and power division ratio at the same time, and can be widely used in the fields of antennas, amplifiers and even millimeter waves. For today's multi-standard, multi-standard wireless Communication requires high research value. Background technique [0002] As a radio frequency passive device, couplers are widely used in array antennas, mixers, power amplifiers and many other aspects. With the rapid development of the wireless communication field and the requirement for multifunctional RF devices, couplers with non-traditional structures have been continuously developed, which can provide multiple functions and good performance at the same time. In order to meet the requirements of more practical communication applications, couplers with many functions such as radar, satellite, broadband coupler, and dua...
