Design of the novel DVB‐H antenna for mobile handheld terminal

We have proposed a novel digital video broadcast for handheld (DVB-H) antenna for mobile handheld terminal using a U-shaped radiator and a simple matching circuit. The matching circuit consists of two chip capacitors and one chip inductor, and is used for achieving an improved impedance matching over the DVB-H frequency band of 470–702 MHz. The proposed antenna was designed, fabricated, and measured. The proposed antenna covers the entire DVB-H band for VSWR < 2.5. The simulated antenna gain varies from 2.1 to 2.8 dBi over the operating frequency range. The obtained radiation patterns are very close to those of a conventional dipole antenna. Details of the proposed antenna design and the simulated and measured results are presented and discussed. © 2007 Wiley Periodicals, Inc.
