Abstract
Description
Technical field
[0001] The present invention relates to an antenna, in particular to an antenna placed in an electronic device and working under an ISM (Industry, Science, Medicine) frequency band.
Background technique
[0002] For electronic devices with communication receiving functions, with the trend of miniaturization and design simplification of electronic devices, there is a corresponding demand for miniaturization of the volume of various communication equipment including antennas. The planar inverted "F" antenna ( Planar Inverted-F Antenna (PIFA) is a commonly used small antenna suitable for communication terminals. Please refer to Fig. 1 for the prior art, which is a plane inverted "F" antenna, the plane inverted "F" antenna 1 includes a grounding sheet 11, a radiation sheet 12, a short circuit sheet 13 and a TEM (transverse electromagnetic wave) transmission line 14, The two ends of the shorting plate 13 are respectively welded on the ground plate 11 and the ...

Embodiment Construction
[0014] Referring to FIG. 2 , the antenna of the present invention includes an antenna body 2 and a feeder 3 , wherein the antenna body 2 includes a connector 22 and two metal arms 21 extending from two free ends of the connector 22 . The connector 22 includes a first side wall 221, a second side wall 222 and a top wall 223 connecting the first side wall 221 and the second side wall 222. One ends of the two side walls 222 protrude. In this embodiment, the two metal arms 21 extend outward from the plane where the connecting member 22 is located, and have an included angle θ with the plane where the connecting member 22 is located. The feeder 3 usually includes a first conductor and a second conductor. In this embodiment, the feeder 3 is a coaxial cable, which is composed of a core wire 31 and a shielding layer 32. The core wire 31 at one end of the coaxial cable is connected to the connector 22 The first side wall 221 of the connector 22 is welded to form a first connection poi...
