Embodiment Construction

[0018] The invention mainly relates to a handheld device and its planar antenna. The hand-held device can control the planar antenna to operate in multiple modes by setting a control element on the hand-held device or the planar antenna without increasing the overall volume of the planar antenna and without changing the basic structure of the planar antenna. different center frequencies to achieve the effect of supporting multi-band operation. The following examples are used to illustrate the technical content of the present invention, but not to limit the scope of the present invention. It should be noted that, in the following embodiments and drawings, elements irrelevant to the present invention have been omitted and not shown. In addition, the dimensional relationship among the various elements in the drawings is only for easy understanding, and is not intended to limit the actual scale.

Abstract

A handheld device and a planar antenna thereof are provided. The planar antenna comprises a radiator having a feeding point, a first short point and a second short point. The feeding point is coupled to a circuit board of the handheld device so that the handheld device transmits and receives a RF (radio frequency) signal through the radiator. The first short point is coupled to a ground of the circuit board so as to be grounded. A control element is disposed on the handheld device or the planar antenna in order to control the second short point to be selectively electrically coupled to the ground so that the planar antenna can operate at two different central frequencies. Furthermore, the planar antenna can operate at multiple central frequencies by changing a position of the second short point contacted to the radiator.

Description

technical field [0001] The invention relates to a handheld device and its planar antenna. Specifically, the handheld device of the present invention can operate at multiple center frequencies by controlling the short-circuit point of its planar antenna. Background technique [0002] With the vigorous development of wireless communication, people's demand for wireless communication is also increasing day by day. Among various wireless communication products, portable handheld devices are most needed by people nowadays. In order to meet people's demand for hand-held devices to be thinner and lighter, the types of antennas of the hand-held devices are also changing with each passing day. Currently, hidden antennas that hide antennas in handheld devices are a major market mainstream, and among hidden antennas, planar antennas are the most popular. The main reason for the above is that the use of a planar antenna can greatly reduce the space occupied by the antenna in the hand...
