In this work, computationally efficient design optimization of frequency selective surface (FSS)-loaded ultra-wideband Vivaldi antenna via the use data-driven surrogate model is studied. The proposed methodology consists a multi-layer FSS structure aimed for performance improvement design, which makes multi-objective multi-dimensional problem. For having fast and accurate process, alongside met...

Compact fifth-generation (5G) low-frequency band filtering antennas (filtennas) with stable directive radiation patterns, improved bandwidth (BW), and gain are designed, fabricated, tested in this research. The proposed filtennas achieved by combining the predesigned compact 5G (5.975 – 7.125 GHz) third-order uniform non-uniform transmission line hairpin bandpass filters (UTL NTL HPBFs) ultrawi...
