Switchable non-physical LTE/WWAN antenna
2017
This research proposes a switchable non-physical LTE/WWAN antenna. It adopts the metal zone around the hinge slot, created by the existing display ground plane, keyboard ground plane, and metal hinges, to create the radiator. It then feeds a signal at the proper position in the hinge slot to effectively excite the resonance modes of the loop path around the hinge slot. Moreover, it adopts switchable feeding points to cover the LTE700/2300/2500 triple-bands required by LTE and the GSM850/900/1800/1900/UMTS penta-bands required by WWAN, respectively, and fulfils the operating requirements of fourth generation communication. In addition, since no additional deployment space and structure design for antenna is required, the design can resolve the space requirement for communication device, and provide new antenna design technology.
