Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.
See also Fig. 1, the utility model multifrequency antenna is a dull and stereotyped inverted F shaped antenna, is located on the circuit board (figure does not show) in the electronic installation, and it comprises base portion 1, high-frequency radiation part 2, low frequency radiation portion 3 and grounding parts 4.
Base portion 1 roughly is a rectangle sheet, and this base portion 1 has first lateral margin 101 and second lateral margin 102 relative with first lateral margin 101.These base portion 1 one ends are provided with load point 11 near second lateral margin, 102 places.
One end of first lateral margin 101 of this base portion 1 and its ora terminalis be evenly vertical to stretch out and forms the high-frequency radiation part 2 of strip.In the present embodiment, this high-frequency radiation part 2 extends upward with respect to the plane inclination at base portion 1 place, promptly tilts to extend upward with respect to circuit board.
The other end of first lateral margin 101 of this base portion 1 and the evenly vertical formation low frequency radiation portion 3 that stretches out of its ora terminalis.Particularly, this low frequency radiation portion 3 comprises from the other end of first lateral margin 101 first extension 31 of the strip that forms that vertically stretches out, and be laid between first extension 31 and the high-frequency radiation part 2 and with second extension 32 and the 3rd extension 33 of first extension 31 parallel extension arranged side by side successively.The end of first extension 31 is connected with second extension 32 by first connecting portion 301, and the end of second extension 32 is connected with the 3rd extension 33 by second connecting portion 302.Wherein, first connecting portion 301 offers the end that rectangular fluting 303, the second extensions 32 are connected with first connecting portion 301 and extends to form a convex extension part 304 to first extension, 31 1 sides on high-frequency radiation part 2 and the lateral margin away from base portion 1.
