Low-frequency antenna unit and medium-high frequency antenna element are distributed in 3 both sides of high-frequency coupling arm, pass through the feed pin of signal feed 2 and feedback place
1 forms the LOOP antennas of S types.
Further, the first gap 9 and the second gap 10 form basic annular volume and respectively constitute low frequency 880-
The antenna element of 960Mhz and medium-high frequency 1710-1990Mhz.
Further, hyperfrequency 2300-2700Mhz antenna elements are introduced by high-frequency coupling arm 3.
Further, tuning switch is introduced in feedback place 1, the switch is switched for four formula tuned radio-frequency of hilted broadsword, tuned
Three road RF1, RF2 and RF3 tunings in switch are set, and then introduce 690-803MHz antenna elements, 790-894MHz antenna elements
With 880-960Mhz antenna elements.
Further, button bit 8, audio port 6 and MIC mouths 7 are further included, is realized using LDS techniques.
The beneficial effects of the utility model are：
Using the volume integral LOOP technologies of (volumereuse), full frequency band is covered by the feature of body broader bandwidth,
Particularly from the low frequency bandwidth of 790-960Mhz；Tuning switch is innovatively introduced in the technology of the LOOP, place is gone back in antenna
It as switch foot, reduces under switching loss, covers ultralow frequency 700Mhz；It is tuned, pulls out by increasing π type matching networks
Hyperfrequency resonant mode makes it meet 2300-2700 performance indicators, and the day of full frequency band bandwidth is reached by more than technology and method
Line, so as to meet the antenna performance requirement of high screen accounting mobile phone.
