We asymmetric discarding the substrate between the metal fins to adjust the beam direction making the beam squint smaller, and etched some slots on both fins to extend the lower-end bandwidth and improve the radiation directivity. The proposed design operates over 19-84GHz with return loss < -10dB and present a maximum gain of 13.09 dB at 48GHz. Numerical assessments to validate the proposed antenna design are conducted. ? 2021 Taiwan Microwave Association. |
