    (IEEE, 2021) Khodja, Khalida; Belazzoug, Massinisssa; Atia, Salim; Messaoudene, Idris; Denidni, Tayeb A.
    In this paper, a dual-beam array antenna based on triangular dielectric resonator (TDR) is presented for Ka-band applications. It consists of 2×1 radiating elements sharing a common ground plane and plated with a thin copper layer at the upper side. The antenna effectively covers two separate bands (28 GHz and 33GHz) with a double-beam radiation at both operating frequencies. This structure has achieved a return loss lower than -20dB with a corresponding gain of more than 8 dBi at 28GHz and 6dBi at 33GHz, and a high radiation efficiency (≥90%) across each band. The radiation pointing angles are centered at ±28° (28GHz) and ±31° (33GHz) with a wide angular width of more than 30°, respectively
