Resonant periodic structures are known to interact well with radiating elements provided such elements are suitably integrated. A number of configurations have previously shown to enhance gain and improve matching conditions. In order to meet some practical demands in areas of modern communication systems and on-body electronics, metamaterial techniques can be employed to realise simple low profile and high gain antennas. Typical Metamaterial based antenna (MBA) are less susceptible to environmental effects which tend to degrade the antenna’s performance. These problems are pronounced in the VHF-UHF frequency range where electrically ‘small’ high gain antennas are cumbersome and challenging to design. This paper discuses a couple of metamaterial inspired low frequency antenna structures. Firstly, we present a planar wideband dipole antenna integrated into a flat plate metamaterial, and show some parametric results. Secondly, a compact woven antenna for Search and Rescue (SAR) applications is proposed, including a meta surface design acting as a ground plane possible to use in electronic textile systems.
