Abstract :
A novel handset antenna formed by a monopole slot and a monopole strip for the WWAN operation in the 824~960 and 1710~2170 MHz bands is presented. The monopole strip serves as a feed for the monopole slot and also functions as an efficient radiator. The monopole slot generates a quarter-wavelength slot mode in the antenna´s lower band, while the monopole strip contributes its quarter-wavelength mode in the antenna´s upper band. By including a vertical strip which can be enclosed inside the handset casing or be a part of the bezel surrounding the periphery of the handset casing and connected to the bottom edge of the system ground plane, the impedance matching of the excited slot mode can be greatly improved. With a small board space of 9 × 40 mm2, the proposed antenna can cover penta-band WWAN operation.
