Abstract :
A T-shaped monopole antenna is a planar top-loaded monopole antenna and has the attractive feature of a low profile. We propose a novel dual-frequency metal-plate shorted T-shaped monopole antenna suitable for WLAN operation in the 2.4 GHz (2400-2484 MHz) and 5 GHz (5150-5350 and 5725-5875 MHz) bands. A prototype with a low profile of 4 mm only has been constructed. It is suitable for embedding within the narrow space between the top edge of the display and the housing of a laptop computer to operate as an internal antenna. Details of the proposed antenna and the experimental results are presented.
