Problems solved by technology

[0003] In mobile phone antenna design, the traditional Planar Inverted F Antenna (PIFA) is difficult to meet the miniaturization design requirements of wireless communication devices due to the limitation of antenna height and the need to set a large area of ​​conductive parts. More and more designers are turning to wire antenna (wire antenna) as a design method

Embodiment Construction

[0012] figure 1 Shown is a dipole antenna 100 according to a preferred embodiment of the present invention, which can be applied to portable electronic devices with wireless communication functions such as mobile phones or PDAs. The dipole antenna 100 includes a feeding end 10 , a grounding end 20 and a radiator 30 .

[0013] The feed-in terminal 10 is a flat rectangular piece, which can be installed on an existing circuit board (not shown) in the portable electronic device, and is connected with the existing signal feeder provided on the circuit board. The input point (not shown in the figure) is electrically connected to feed the signal to the dipole antenna 100 .

[0014] The ground terminal 20 is a rectangular piece with the same width as the feed-in terminal 10 and a slightly longer length, which is arranged on the same plane as the feed-in terminal 10 . The extension direction of the ground terminal 20 and the feed-in terminal 10 is parallel to each other, one end of t...

Abstract

The invention provides a dipole antenna, comprising a feed-in end, a grounding end and a radiator, wherein the feed-in end and the grounding end are arranged in the same plane; the radiator comprises two symmetrical radiating arms; one end of each of the two radiating arms is respectively and vertically connected to the feed-in end and the grounding end, and the other ends of the two radiating arms are mutually connected; each radiating arm comprises a first radiating zone, a second radiating zone and a third radiating zone which are connected in sequence; the plane of the first radiating zone is vertical to the plane of the feed-in end and the grounding end; the plane of the second radiating zone is parallel to the plane of the feed-in end and the grounding end; and the third radiating area comprises a first piece body coplanar with the first radiating zone and a second piece body coplanar with the second radiating zone. In the dipole antenna, the volume is small, and the covered frequency band is wide.

Description

technical field [0001] The invention relates to an antenna, in particular to a dipole antenna applied to a wireless communication device. Background technique [0002] In mobile phones, personal digital assistants (Personal Digital Assistant, PDA) and other wireless communication devices, the antenna, as a component used to transmit and receive radio waves to transmit and exchange radio signals, is undoubtedly one of the most important components in wireless communication devices one. At present, wireless communication devices generally need to have the function of communicating in dual-frequency or more frequency bands, so their antenna devices generally use dual-frequency or multi-frequency antennas. [0003] In mobile phone antenna design, the traditional Planar Inverted F Antenna (PIFA) is difficult to meet the miniaturization design requirements of wireless communication devices due to the limitation of antenna height and the need to set a large area of ​​conductive pa...
