This paper presents a dual-band internal WLAN PIFA for 2.4/5 GHz laptop applications in consideration of the influences of laptop housing and LCD. The prototype antenna is modified when installed along the perimeter of the display panel of the laptop housing. The proposed antenna has a small ground plane and achieves an impedance bandwidth of 250 MHz (2.37–2.62 GHz(in Bluetooth band and 950 MHz (4.98–5.93 GHz(near 5 GHz in WLAN band within 2:1 voltage standing wave ratio (VSWR(. It also shows good antenna gain with small volume. These features make it an alternative for use in dual-band WLAN antennas. Design details for the proposed antenna in the case of the antenna itself, and the application of laptop PC housing are described, and experimental results of the antenna achievements are investigated and discussed.
