An Eight-band WWAN/LTE By-Hinge Printed Inverted-F Antenna on Laptop Computer

This paper presents a printed inverted-F antenna mounted on a laptop computer for eight-band WWAN/LTE operations. The PIFA is inserted in an area bounded by the right hinge and the two ground planes of the laptop so as to integrate these metal surroundings as part of the radiation structure. The resulting operating bands can cover the lower frequency band of 698-960 MHz for LTE700/GSM850/900 operations and the higher frequency range of 1710-2690 MHz for GSM1800/1900/UMTS/LTE2300/2500 operations. Simulated efficiencies are mostly greatly than 50% except for the frequencies near the lower edge of the lower frequency band.
