Bandwidth and Directivity Enhancement of Loop Antenna by Nonperiodic Distribution of Mu-Negative Metamaterial Unit Cells
(2016)The theory, design, analysis, and verification of a wideband and unidirectional loop antenna loaded with mu-negative (MNG) metamaterial unit cells is presented. It is shown that by nonperiodic positioning of MNG unit cells ...

Bandwidth and directivity enhancement of metamaterial-loaded loop antennas for microwave imaging applications
(Institute of Electrical and Electronics Engineers Inc., 2017)Compact, wideband and unidirectional loop antennas are presented, that are based on a conventional planar loop antenna that is loaded in a mu-negative (MNG) fashion with series capacitors, enabling a mu-zero (MZR) resonance ...

Compact Wideband Loop Antenna Partially Loaded With Mu-Negative Metamaterial Unit Cells for Directivity Enhancement
(2016)A wideband and unidirectional loop antenna partially loaded with mu-negative (MNG) metamaterial unit cells is presented. To reduce the electrical size of the antenna, its first resonance is formed by capacitively loading ...

Miniaturization of Planar Yagi Antennas Using Mu-Negative Metamaterial-Loaded Reflector
(2017)A technique to reduce the size and enhance the operating bandwidth (BW) of planar Yagi antennas, while maintaining their unidirectional radiation characteristics, is proposed in this paper. In this technique, the reflector ...
