Various efficient electrically small antennas have been designed based on metamaterial shells and metamaterial-inspired structures. Several metamaterial-inspired antennas have been fabricated and the results have confirmed the design predictions. The Z antenna, a simplified version of the metamaterial-inspired 2D electric EZ antenna, has been designed and tested successfully. The experimentally tested...
A uni-planar, easy for integration and compact antenna for millimeter wave applications is presented in this paper. The concept of metamaterials is employed to realize the antenna miniaturization. For the designed antenna, a small rectangular semi-loop performs as the radiating element. Metamaterial-inspired parallel strips are introduced that are coupled to the original antenna. It is found that,...
