Abstract

A low profile, miniature, horizontally polarized loop antenna is proposed to work in the 400-450 MHz UHF band. The wide band coverage is obtained through continuous frequency reconfiguration through varicap loaded ends of the loop. A study on miniaturization effects on performance as well as on matching loads is presented. After the optimization the proposed antenna confirms to work as a magnetic dipole with a total efficiency greater than 90% between 400 MHz and 440 MHz.
