Abstract

The design of a tilted-beam compact spiral antenna is investigated for 3.5-6 GHz. A partially absorbing dielectric lens (PADL) is placed above the spiral and its thicknesses are independently varied to adjust the tilt angles at different frequencies. The geometry is optimized numerically, fabricated using 3D printing and tested. A consistent tilt angle is measured with good impedance matching and gain. © 2023 IEEE.
