New Wideband Wearable Meta-Material Antennas for Communication Applications
8.1 INTRODUCTION
Microstrip antennas are widely used in communication systems. They have several advantages such as low profile, flexibility, light weight, small volume, and low production cost. Compact printed antennas are discussed in journals and books [1–4]. However, small printed antennas suffer from low efficiency. Meta material technology is used to design small printed antennas with high efficiency. Printed wearable antennas are described in Ref. [5]. Artificial media with negative dielectric permittivity are described in Ref. [6]. Periodic split-ring resonator (SRR) and metallic post structures may be used to design materials with dielectric constant ...
