Embodiment Construction
[0012] see figure 1 and figure 2 As shown, it is a perspective view of the first embodiment of the present invention. In the first embodiment, the multi-frequency antenna 1 includes a ground metal piece 10 , a first radiating metal piece 11 , a second radiating metal piece 12 , a shorting metal arm 13 and a coaxial transmission line 14 .
[0013] The ground metal sheet 10 has an edge 101 , and a short-circuit point 102 is provided near the middle of the edge 101 , and the short-circuit metal arm 13 vertically extends upward from the short-circuit point 102 . The first radiating metal piece 11 is a rectangular metal piece extending from the other end of the short-circuiting metal arm 13 in a direction away from the second radiating metal piece 12 , and is located above the grounding metal piece 10 and substantially parallel to the grounding metal piece 10 . The second radiating metal sheet 12 is a bent rectangular metal sheet extending vertically from the grounding metal she...

The invention relates to a multi-frequency antenna which comprises a grounding metal sheet, a first radiation metal sheet, a second radiation metal sheet, a short circuit metal arm and a feed-in coaxial transmission line, wherein the grounding metal sheet is provided with an edge and a grounding point; the first radiation metal sheet and the grounding metal sheet are arranged at an interval; the second radiation metal sheet extends upward from the edge of the grounding metal sheet; the short circuit metal arm is positioned between the first radiation metal sheet and the grounding metal sheet; the feed-in coaxial transmission line is provided with a center lead for transmitting signals and an outer grounding conductor; a short circuit point is arranged on the edge, one end of the short circuit metal arm is connected to one end of the first radiation metal sheet, the other end of the short circuit metal arm is connected to the short circuit point of the grounding metal sheet, and a feed-in point is arranged on the short circuit metal arm; the first radiation metal sheet is extended along the direction far away from the second radiation metal sheet, and the first radiation metal sheet, the second radiation metal sheet and the short circuit metal arm together form a gap; and the first radiation metal sheet and the second radiation metal sheet respectively work at a first working band and a second working band. The multi-frequency antenna of the invention has the advantages of simple structure and small occupation of the inner space of electronic equipment.
Description
【Technical field】 [0001] The invention relates to a multi-frequency antenna, in particular to a multi-frequency antenna applied to wireless communication products. 【Background technique】 [0002] With the rapid development of wireless networks in recent years, the performance requirements of antennas have also gradually increased. The antennas integrated in electronic equipment not only require a reduction in size, but also must have the characteristics of built-in, integration, and multi-band. Be competitive in the market. [0003] At present, there are some commonly used dual-frequency inverted-F antenna designs for electronic communication products suitable for wireless networks. These antennas usually include a first radiating arm, a second radiating arm, a short-circuit metal arm, a ground plate and a feeder , wherein the first radiating arm and the second radiating arm are connected to one end of the short-circuiting metal arm and extend to both sides in opposite dire...
