【摘要】 本文提出了一种基于HTCC(高温共烧陶瓷)材料的紧耦合平面偶极子天线阵列。通过在偶极子上加载开路与短路金属通孔,改善天线输入端口阻抗,从而显著拓宽了偶极子的阻抗带宽。基于此加载的偶极子的宽带天线能够在12～18 GHz实现VSWR<3 (相对带宽为42.7%),相位扫描±45°,天线剖面高度为0.108λ_h。更多还原

【Abstract】 This paper presents a tightly coupled planar dipole antenna array based on high-temperature co-fired ceramic(HTCC) material.By loading open-and short-circuited metal vias onto the dipole,the input impedance at the antenna’s feed port is improved,resulting in a significantly broadened impedance bandwidth.The developed broadband antenna based on this loaded dipole achieves a VSWR <3(42.7% relative bandwidth) over 12-18 GHz,with a phase scanning range of ±45° and an antenna profile height of 0.108λ.更多还原
