Abstract

This work addresses a wideband dual-beam 1x4 phased MIMO array antenna with a hybrid coupler for Industrial, Scientific and Medical (ISM) bands applications at 2.4-2.5 GHz. We engineered, refined, and reduced the fundamental component utilizing the novel concept of an advanced curved quarter-wave impedance adapter, achieving a 50% reduction in size relative to comparable designs documented in the literature. The fundamental component operates at 2.45 GHz, including a narrow bandwidth of 26 MHz and a maximum gain of 7.21 dB. Subsequently, a lossless magic-T power splitter is employed to feed two identical miniaturized elements resulting in a compact 1 × 2 array antenna with miniaturized size and enhanced performance. The results obtained show that the miniaturized 1 × 2 array antenna resonate at 2.45 GHz with a narrow impedance bandwidth of 52 MHz, peak gain of 9.41 dB and a peak directivity of 9.48 dB at 2.45 GHz. To broaden the narrow bandwidth and to enhance gain, directivity and radiation coverage area, a 3 dB hybrid coupler is used to feed two identical miniaturized 1 × 2 array antennas resulting a wideband directional dual-beam MIMO phased 1 × 4 array antenna. The proposed dual-beam array antenna prototype has been designed and fabricated on a substrate Rogers RT/duroid 5880 with the following parameters: relative permittivity ε_r = 2.2, dielectric loss tangent of 0.0009, and total size of 240 × 136 × 1.56 mm³. The simulation results are corroborated by experiments that verified the proposed dual-beam MIMO array antenna which exhibits a high gain of 11.2 dB, effective adaptation, an expanded bandwidth of 1.22 GHz, in addition to its MIMO capability and the dual beams oriented at ±30˚, achieved through switching between the two input feed ports of the hybrid coupler.
