Design of GPS/WLAN antenna for full metal cover tablet PC

To accommodate the need of full metal tablet PC, an antenna designed to be applicable to GPS, WLAN and communication is proposed. Some techniques of frequency adjustment and impedance matching are employed, such as the use of shorted metal post, and slotting. The proposed antenna is planar and can be fabricated by printed circuit board technology. High efficiency and gain compared to traditional antenna of tablet PC are obtained.
