Embodiment Construction

[0019] With the vigorous development of wireless communication, many communication tools tend to be miniaturized. In order to meet this demand, some built-in antennas are also required to be small in size. For example, the inverted F-shaped planar antenna (PIFA) has near-omnidirectional radiation characteristics. and small size advantages. The mobile phone antenna disclosed by the invention has the advantages of an inverted F planar antenna (PIFA), and does not occupy the space inside the mobile phone, thereby meeting the requirements of miniaturization and rich functions of the mobile phone.

[0020] Attached below figure 1 The structural schematic diagram and preferred embodiment of the mobile phone antenna are described in detail for the mobile phone antenna of the present invention.

[0021] The mobile phone antenna of the present invention includes a metal layer 1 , a grounding device 5 , and a feeder device 6 . Meanwhile, the metal layer 1 is divided into several region...

Abstract

Characters of the antenna are that the antenna consists of metal layer of keyset of handset. The metal layer includes groove, grounding device, and feed line. The invention also discloses a handset with built-in antenna. The handset includes print circuit board, and metal layer of keyset. Being as antenna, the metal layer is in use for receiving and transmitting wireless signal. The metal layer includes groove in order to satisfy requirement of antenna size from frequency band. Being setup on the metal layer, the feed line unit connected to RF sect of print circuit board is in use for receiving and transmitting radio frequency. The grounding device setup on metal layer is connected to ground of the print circuit board.

Description

technical field [0001] The invention relates to a mobile phone antenna and a mobile phone, in particular to an inverted F planar antenna (PIFA) and a built-in antenna mobile phone. Background technique [0002] With the development of mobile communication, WLAN, and bluetooth technologies, higher requirements are put forward for terminal devices implementing these applications, among which the common requirement is to reduce the size of the terminal devices. Reducing the volume of the antenna is the key to reducing the volume of the entire terminal device. In mobile phones, although the inverted F-shaped planar antenna (PIFA) can reduce the volume of the mobile phone, the inverted F-shaped planar antenna (PIFA) itself still takes up valuable internal space of the mobile phone. [0003] Mobile phones are now becoming smaller and more functional. Each function needs to be provided with a device supporting the function inside the mobile phone accordingly, so the contradiction...
