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, second lateral margin 102 relative with first lateral margin 101 and relative first ora terminalis 103 and second ora terminalis 104.First ora terminalis 103 of this base portion 1 and second lateral margin, 102 intersections are provided with load point 11, second lateral margin, the 102 1 end places and second ora terminalis 104 evenly outwards extend in parallel side by side with second lateral margin 102 behind the vertical extent again and are formed with connecting portion 12, and the end of connecting portion 12 is provided with earth point 13.The end of connecting portion 12 extends the grounding parts 4 of strip to base portion 1 one sides.
Described high-frequency radiation part 2 is strip, and its first lateral margin 101 by base portion 1 is close to second ora terminalis, 104 places and extends perpendicular to first lateral margin 101.High-frequency radiation part 2 offers first groove 21 that extends to base portion 1 on a lateral margin of first ora terminalis 103.
