Abstract

An embodiment of the invention discloses a reconfigurable antenna. A radiator body is attached to the lower surface of a first circular dielectric substrate; a metal grounding plate is attached to the upper surface of the first circular dielectric substrate; a coaxial feeder line is arranged inside the first circular dielectric substrate; an inner conductor of the coaxial feeder line is electrically connected with the radiator body, and an outer conductor of the coaxial feeder line is electrically connected with the metal grounding plate; a plurality of metal patches are attached on the upper surface of a second circular dielectric substrate; the circle center of the upper surface of the first circular dielectric substrate is provided with a cylinder perpendicular to the first circular dielectric substrate; the circle center of the second circular dielectric substrate is provided with a run-through circular hole; the cylinder is inserted into the circular hole to enable the upper surface of the first circular dielectric substrate to be contacted with the lower surface of the second circular dielectric substrate. The embodiment of the invention also discloses a terminal device. According to the reconfigurable antenna and the terminal device, the frequency point of the reconfigurable antenna is adjusted in a passive manner, and the design difficulty of the antenna is reduced.

Description

technical field [0001] The present invention relates to the field of antennas, in particular to a reconfigurable antenna and terminal equipment. Background technique [0002] With the development of mobile communication technology, more stringent requirements are put forward for antennas of mobile terminals such as mobile phones. At present, when designing mobile phone antennas, if you want to design a communication main antenna that meets the requirements of 2G / 3G / 4G, you need the mobile phone main antenna to be able to cover at least 1880MHz-2650MHz. At present, the frequency band of the main antenna is not wide enough when many mobile phone antennas are designed. This defect can seriously affect the quality of communication. In this case, the emergence of reconfigurable frequency band can solve this problem well. When the antenna is working, the intelligent system senses the specific working frequency band at a specific time. Then the antenna automatically switches to...
