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 ...

Gain Enhancement of Wideband Metamaterial-Loaded Loop Antenna with Tightly Coupled Arc-Shaped Directors
(2017)A wideband and unidirectional loop antenna with enhanced and stable gain is presented. To reduce the size of the antenna, the loop is loaded with three mu-negative (MNG) metamaterial unit-cells. The proposed unit-cells ...
