Embodiment Construction
[0032] Below, combined with figure 1 And attached figure 2 , the specific embodiment of the present invention will be further described.
[0033] Such as figure 1 As shown, a preferred embodiment of the present invention is a mobile terminal antenna device that surrounds the feed pin, including the mobile terminal main board 1, the feed pin 2, the feed pin 3, and the antenna radiation around the feed pin or the contact area of the feed pin The antenna radiation sheet includes a long branch 4 and a short branch 5 . As shown in Figure 1a, the long branch 4 of the antenna circles more than half a circle around the contact area between the feeder foot 2 and the feeder foot 3 in the direction of the arrow, so that when the primary resonance frequency of the long branch 4 is 1.57GHz, the second The resonant frequency is also higher than the 2.4GHz frequency band, and then the short branch 5 is used to further reduce the high frequency resonant frequency of the antenna, which j...
