Numerical and experimental generated data during project https://doi.org/10.1109/LAWP.2024.3429499

The dataset was generated during a project aimed at designing an extremely compact frequency-reconfigurable self-diplexing antenna based on fluidic channels for sub-6 GHz applications. The self-diplexing antenna is realized by using slot-loaded half-mode and quarter-mode substrate-integrated rectangular cavities, which take an extremely compact size. The high isolation is obtained by employing the loading slot and the orthogonal feed lines, and three fluidic vias are bored from the bottom plane and filled with different dielectric liquids to enable frequency reconfigurability with little effect on the antenna radiation. The constructed antenna prototype has a small footprint of 0.078λ2g with 15% and 16% reconfigurability in the lower and upper-frequency bands, respectively. The measured results show 31.3 dB isolation, 3.28 dBi gain for the low band, and 4.5 dBi gain for the high band, respectively.
