Gain Improvement of Bidirectional Substrate‐Integrated Waveguide‐Based Circular Cavity‐Backed Hexagonal Split Ring‐Shaped Slotted Antenna Using Metamaterial as Superstrate

International Journal of Antennas and Propagation, Volume 2025, Issue 1, 2025.
A low profile substrate‐integrated waveguide (SIW)‐based circular cavity‐backed slotted antenna is proposed at an operating frequency of 5.42 GHz for wireless applications in U‐NII‐2B band in the TM010 fundamental mode. Two hexagonal split ring‐shaped slots of 7 and 4 mm radius are placed on the patch as well as on the ground plane, resulting in ...
