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 mm 3 , 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.
