摘要

本文提出了一种用于DVB-H(手持式数字视频广播)应用的变容调谐天线设计新技术。该方案基于加载平面倒f天线(PIFA)设计。天线的谐振频率由电气控制，从而实现宽带操作。由变容二极管组成的调谐电路实现所需的天线调谐阻抗。验证了所提出的方法，创建了覆盖(470 - 750)MHz并满足指定增益要求的可调谐天线。

A Varactor-Tuned DVB-H Antenna

This paper presents a novel technique for the design of a varactor-tuned antenna for DVB-H (digital video broadcast-handheld) application. This solution is based on loaded planar inverted-F antenna (PIFA) design. Resonance frequency of the antenna is electrically controlled and thus wideband operation is achieved. A tuning circuit consisting of a varactor diode realizes the needed antenna tuning impedances. Proposed method is verified creating a tunable antenna that covers (470 - 750) MHz and fulfills the specified gain requirement.
