Embodiment Construction

[0034] figure 1 A schematic diagram showing the electronic device 100 and a nearby human body HB according to an embodiment of the present invention. The electronic device 100 can be installed in a mobile device, such as a smart phone, a tablet computer, or a notebook computer. Such as figure 1 As shown, the electronic device 100 includes: a sensing pad (SensingPad) 110 , a proximity sensor (Proximity Sensor) 120 , a controller 130 , and an adjustable antenna element 150 . The sensing board 110 can be made of metal. Since the human body HB can be regarded as a conductor, the sensing board 110 and the nearby human body HB can form a virtual capacitor, wherein a capacitance C1 of the virtual capacitor is determined according to the distance between the sensing board 110 and the human body HB. When the human body HB approaches or moves away from the sensing board 110 , the radiation characteristic of the adjustable antenna element 150 of the electronic device 100 may change. ...

Abstract

Provided is an electronic device and a control method thereof. The electronic device comprises a sensor plate, a proximity sensor, a controller and an adjustable antenna element. The proximity sensor is coupled to the sensor plate and is used for detecting a capacitance value between the human body and the sensor plate. The controller is coupled to the proximity sensor and generates a first control signal according to the capacitance value. The adjustable antenna element is coupled to the controller and comprises a main radiating part, a plurality of adjusting parts and a plurality of switchers. The switchers are respectively coupled between the adjusting parts and the main radiating part, and selectively connect or do not connect the adjusting parts and the main radiating part according to the control signal so as to correct an operation frequency band of the adjustable antenna element. When the human body is close to the electronic device, the electronic device can correct the operation frequency band according to the position of the human body so as to maintain good communication quality.

Description

technical field [0001] The present invention relates to an electronic device and a control method thereof, in particular to an electronic device capable of retuning an operating frequency band according to the position of a nearby human body. Background technique [0002] Traditional tablet computers or smart phones often use embedded antenna design. Due to the limited internal space of mobile devices, some manufacturers use hidden antennas, while others use the casing of the mobile device as part of the antenna. [0003] However, the impact of human contact with mobile devices is unavoidable. When a person's palm or finger touches the radiator of the antenna, the original resonant mode and radiation characteristics of the antenna are completely changed, resulting in a decrease in communication quality. Contents of the invention [0004] In order to solve the above problems, the present invention provides an electronic device and a control method thereof. When the human...
