Structural slotted waveguide antennas for multirotor UAV radio altimeter
2014 IEEE International Conference on Signal Processing, Communications and Computing (ICSPCC 2014)——Z-slots are presumed to offer a structural advantage over conventional inclined slots for narrow wall slotted waveguide antennas,in that the corners of the rectangular are not cut and consequently will not weaken a structural tube as much.Initial structural simulations are shown to confirm this assumption.This slot configuration was also further investigated as radiating slots on standing wave type slotted waveguide antennas.Fan-beam antennas having 10 to 30 slots were successfully designed for 10GHz using a commercially available antenna simulator,having directivities from 16 to 21dbi and aperture efficiency of 60%.
