Compound Reconfigurable Bio-Inspired Antenna Design

This research describes a bio-inspired antenna design derived from the shape of a three-petal flower intended for multiple agilities. The proposed design incorporated three PIN diodes corresponding to 8 modes of operation, to achieve pattern diversity and multiple frequency reconfigurable bands. The diodes have been connected between the main hexagonal microstrip radiator and the external parasitic elements, which have a flower petal shape. Pattern reconfigurability has been achieved at 4.675 GHz and 5.2 GHz frequencies, and multi-band frequency reconfigurability was achieved at various center frequencies within the C-band from 4 to 8 GHz range where it can support modern applications such as 5G NR (new radio) and Wi-Fi 6 communications.
