A compact dual-band antenna design for UMTS/HSDAP-based data-card applications

A novel compact dual-band antenna based on meander-line folded monopole is designed to cover UMTS frequency bands of I, III and VIII under the physical size constraint of 30 x 5.1 x 4 mm³ for UMTS/HSDPA-based data card applications. Good agreement between the numerical results and measured data is observed. The excellent measured gain performance at far-field chamber validates this useful design approach.
