Frequency reconfigurable antenna for DVB‐H applications

Abstract

This article presents a new reconfigurable DVB‐H antenna for a portable TV or a tablet PC device. The antenna consists in a folded monopole loaded by a diode varactor combined with an open stub used to match the antenna. Design procedure and equivalent model are presented. A prototype is realized and measured; return loss and efficiency are presented. A minimal total efficiency of 27% is reported at the whole DVB‐H band. © 2011 Wiley Periodicals, Inc.

Miniature Reconfigurable Antenna with Magneto Dielectric Substrate for DVB‐H Band

“…We previously designed a 30 3 30 mm 2 PIFA loaded with a varactor diode on a 230 3 130 mm 2 PCB [11]. Thanks to this technique, we reach the limit of miniaturization for this structure with respect to the DVB-H standard.…”
