title = "A Compact Footprint Frequency-Reconfigurable Filtering Patch Antenna Based on U-Slots",
abstract = "A simple frequency-reconfigurable filtering patch antenna with a compact footprint is presented in this paper. The proposed design achieves the filtering functionality using two U-slots. Then, a varactor diode is integrated onto each U-slot to achieve frequency reconfigurability. In simulations, the proposed design achieves a 14.8\% frequency tuning range with respect to the central frequency, while maintaining a gain suppression level of at least 10.5 dB in the broadside direction. Compared to typical previously published designs, the proposed structure has a more compact footprint (0.28 × 0.25 λ0) and utilizes fewer varactor diodes, where only one bias voltage is required.",
