Double rectangular meander line loop monopole antenna for miniaturisation and bandwidth

The aim of this reported work was to achieve miniaturisation of an antenna for a wireless mic system covering the 216-224 MHz band. A double rectangular loop structure using a meander line was applied for size reduction and the broad bandwidth of the antenna. As a result of the installation of the mic, a length reduction ratio of 91.3% at 221 MHz and -10 dB bandwidth of 9.85 MHz (4.45%) were obtained.
