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 ...
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 ...
