Skip‐Connected CNN Exploiting BNN Surrogate for Antenna Modelling

International Journal of Antennas and Propagation, Volume 2025, Issue 1, 2025.
The combination of evolutionary algorithms with full‐wave electromagnetic (EM) simulation software is an effective method for antenna optimal design. However, the high computational cost of calling the full‐wave EM simulation hundreds or thousands of times makes it unacceptable in terms of design time.

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 ...
