A Low-Profile Dielectric Resonator Antenna With Compact-Size and Wide Bandwidth by Using Metasurface
A dielectric resonator antenna (DRA) with the loading of metasurface (MS) is proposed for low-profile, wide-bandwidth and compact-size.Firstly, an MS structure consisting of 6 × 6 periodic metallic patch cells is loaded above the DRA.It aims to excite an additional TM surface wave above the fundamental TE111 mode of the rectangular DRA.Then,
