  • Built-in straight mobile antenna type dual band antenna assembly with improved HAC performance
    Patent number: 8164524
    Abstract: A built-in straight mobile antenna type dual band antenna assembly includes a circuit board, a first radiator transversely arranged on one end of the circuit board and having a first resonance frequency, and a second radiator longitudinally arranged on one lateral side of the circuit board. The first radiator and the second radiator constitute an L-shaped structure for signal input through a feed end, and are connected to a ground plane on the circuit board through a common grounding lug.
    Type: Grant

  • Multi-band HAC compatible antenna module
    Patent number: 8115682
    Abstract: A multi-band HAC compatible antenna module having a metal shield arranged around the built-in antenna for resonant coupling with the antenna to lower electromagnetic interference and to improves hearing aids compatibility characteristic. When compared with a reference antenna without metal shield, the multi-band HAC compatible antenna module shows 3 dB˜4 dB HAC improvement in GSM850 and GSM900, and 1 dB HAC improvement in DCS and PCS bands.
