Surface integrated waveguide fed Antipodal Fermi-Linear Tapered Slot Antenna at 28 GHz

To obtain wide bandwidth and high gain at millimeter wave frequency, Antipodal Fermi-Linear Tapered Slot Antenna (AFLTSA) is proposed. The proposed antenna achieves wide bandwidth from 23 to 33 GHz as well as flat gain of 14.5 dBi over wide operating frequency band. It achieves the side lobe level of -8 dB in H Plane and -16 dB in E plane. Proposed design also achieves the front-to-back ratio of -20 dB and symmetric pattern.
