摘要：

A novel dual-band flat-plate antenna with a shorted parasitic element for an internal laptop Antenna for WLAN operation is presented. The proposed antenna is suitable to be integrated with the supporting metal frame fort he display of the laptop and shows a low profile of 5 mm above the metal frame, thus making it easily embedded within the casing of the laptop as an internal antenna. Moreover, the proposed antenna can provide two separate impedance bandwidths of 190 MHz (about 8% centered at 2.4 GHz) and 2140 MHz (about 39% centered at 5.5 GHz), making it easily cover the required bandwidths for. WLAN operation in the 2.4 GHz band (about 3.4% bandwidth required) and 5.2/5.8 GHz bands (about 13% bandwidth required). The proposed antenna is studied in detail in this study, and experimental and simulation results are presented.
