A tunable planar inverted-f antenna for digital video broadcast-handheld applications

A compact varactor-tuned planar inverted-F antenna is introduced for digital video broadcast-handheld (DVB-H) applications. The antenna size is 20 × 40 × 5 mm3, making it particularly suitable as an internal antenna. A full-wave simulator is used to calculate the scattering matrix of the antenna as a two port network. A circuit model including the two-port antenna and its tuning circuitry is simulated using a circuit simulator. The simulation results show that the antenna is continuously tunable within the entire frequency range of the DVB-H standard, 470–702 MHz. The antenna is prototyped and tested. The measured results are in agreement with the simulation data. © 2012 Wiley Periodicals, Inc. Microwave Opt Technol Lett 54:2635–2638, 2012; View this article online at wileyonlinelibrary.com.
