Problems solved by technology

However, as the functions of handheld electronic devices are greatly improved and the volume is smaller, it is difficult to provide extra space for the planar inverted-F antenna to be grounded downward. However, for the GPS antenna, if the planar inverted-F antenna is not grounded , the size of the radiator is multiplied and it is difficult to achieve the required frequency, which not only increases the cost, but also does not meet the needs of miniaturization of handheld electronic devices

Embodiment Construction

[0017] Please refer to figure 2 , a preferred embodiment of the antenna device 1 of the present invention is an inverted F antenna applied to a global positioning system (GPS), the antenna device 1 includes an antenna 11, which is arranged on a printed circuit board 12, wherein the antenna 11 A radiating portion 111 is at an appropriate distance from the printed circuit board 12, and a feed-in portion 112 of the antenna 11 extends downward from the radiating portion 111, and is connected to a signal feed-in portion on the printed circuit board 12. Point 121 is electrically connected.

[0018] In this embodiment, a wire 123 is arranged on the printed circuit board 12, and the wire 123 is, for example, a printed trace formed directly on the printed circuit board 12, and extends outward from the signal feed-in point 121. It is electrically connected to a ground plane 122 on the printed circuit board 12 , wherein the ground plane 122 is, for example, a short pad.

Abstract

The invention relates to an antenna device, which comprises a circuit board, an antenna and a conducting wire, wherein the circuit board comprises a ground plane and a signal feed-in point; the antenna comprises a radiation part and a feed-in part which is extended outwards from the radiation part, wherein the feed-in part is electrically connected with the signal feed-in point; and the wire is arranged on the circuit board and electrically connected with the ground plane and the signal feed-in point, for example, the conducting wire is a printed circuit which is formed on the circuit board. The antenna device does not need to be provided with a grounding part of the antenna, so as to be capable of effectively reducing the hardware space of an electronic device.

Description

technical field [0001] The present invention relates to an antenna device, in particular to a Planar Inverted-F Antenna (PIFA) device applied to a Global Positioning System (GPS). Background technique [0002] At present, the communication methods of the general public have gradually changed into the era of wireless communication, and wireless communication devices are becoming more and more diversified, such as smart phones, multimedia players, personal digital assistants and applications of global positioning systems (GPS, global positioning system) satellite navigator, etc. Various electronic devices with wireless transmission functions are also being improved towards a thinner, lighter and smaller design concept, so as to achieve electronic products that are more suitable for daily life. [0003] Traditional GPS antennas used in wireless devices are mostly ceramic antennas (chip antennas), patch antennas (patch antennas) or planar inverted F antennas (planar inverted F ...
