Abstract :
The analysis and design of subwavelength metamaterial-based resonant cavity antennas are presented. The antennas under investigation are formed by embedding a feeding source in a cavity composed of a perfect electrical conductor (PEC) surface and a metasurface reflector. The feeding source used in this study is a 2 times 2 microstrip patch array. The effect of the cavity thickness is investigated and its influence on the radiation patterns is reported. Finally, the design of highly directive cavity antennas is presented.
