Two Compact, Wideband, and Decoupled Meander-Line Antennas Based on Metamaterial Concepts

A two-antenna system employing wideband metamaterial-inspired meander-line antennas with a maximum separation of λ 0 /5 is presented, and a very wide measured -10 dB return-loss bandwidth from 3.3 to 6 GHz is obtained. Orthogonal characteristic modes on the ground plane are excited, and the coupling...

Zusammenfassung:A two-antenna system employing wideband metamaterial-inspired meander-line antennas with a maximum separation of λ 0 /5 is presented, and a very wide measured -10 dB return-loss bandwidth from 3.3 to 6 GHz is obtained. Orthogonal characteristic modes on the ground plane are excited, and the coupling between the two antennas is kept below -20 dB over the same frequency band.
