Problems solved by technology

However, the size of the stylus is usually small to facilitate carrying with portable electronic devices, but the antenna design is also limited due to the limited space. Usually, the main design is a single-frequency antenna, and it is difficult to achieve a dual-frequency antenna. Effect
In addition, the limited space of the stylus also limits the setting of the antenna height and clearance area, and the radiation efficiency of the antenna is affected to a certain extent.

Abstract

The invention discloses an antenna structure, which comprises a body, a first radiation part and a second radiation part. The first radiation part and the second radiation part are oppositely arranged; the body covers the first radiation part and the second radiation part; the first radiation part is electrically connected to a feed-in source to feed in current; current flows along the first radiation part to excite a radiation signal of a first mode; the body obtains the current from the first radiation part through coupling; the second radiation part obtains the current from the body throughcoupling; and the current flows along the first radiation part, the body and the second radiation part and is grounded to excite a radiation signal of a second mode. The invention further provides astylus with the antenna structure.

Description

technical field [0001] The invention relates to an antenna structure and a touch pen with the antenna structure. Background technique [0002] With the advancement of wireless communication technology, many portable electronic devices with touch screens, such as mobile phones, tablet computers and personal digital assistants, are equipped with stylus pens. However, the size of the stylus is usually small to facilitate carrying with portable electronic devices, but the antenna design is also limited due to the limited space. Usually, the main design is a single-frequency antenna, and it is difficult to achieve a dual-frequency antenna. Effect. In addition, the limited space of the stylus also limits the setting of the antenna height and clearance area, and the radiation efficiency of the antenna is affected to a certain extent. Contents of the invention [0003] In view of this, it is necessary to provide an antenna structure and a stylus having the antenna structure. ...
