Conference Paper Description

A fully 3D-printed dual-port dielectric resonator antenna (DRA) is presented. It employs an integrated polarizer to obtain right-hand circular polarization (RHCP) over θ = ±45. The isolation is better than 30 dB by introducing a 3D-printed vertical metallic reflector, of width 1 mm, between the excitation ports. The proposed antenna has applications in satellite IoT (S-IoT) as well as 5G/6G beam-switching MIMO areas. The antenna operates in the S-band (2 GHz to 3 GHz). A 10 dB bandwidth of 61 % was achieved in the range 1.72 GHz to 3.22 GHz. The peak gain at 45 was found to be 6.7 dBic with an axial ratio bandwidth of 51.76 % (1.79 GHz to 3.04 GHz).
