摘要

报道了一种四频带频率可重构天线。天线的尺寸为0。67 λ lx 0.67 λ lx 0。13λl，频率为25.25 GHz。天线由辐射贴片中的两个矩形槽(R1和R2)组成，分别在单频段和四频段独立谐振。该天线工作频率分别为25.25、27.97、31.0和33.25GHz，分别为0.71% (25.15 ~ 25.33 ghz)、1.29% (27.74 ~ 28.1 ghz)、1.03% (30.85 ~ 31.17 ghz)和1.63% (32.99 ~ 33.53 ghz)。放置在矩形槽(R2)中间的金属开关有助于实现频率可重构性。当金属开关打开时，天线在单波段共振，当开关关闭时，天线在四波段共振。该天线具有良好的阻抗匹配、增益和稳定的辐射特性。

A Compact Quad Band Frequency Reconfigurable Antenna for 5G and Satellite Applications

A quad band frequency reconfigurable antenna is reported. The antenna has a size of0. 67 λl× 0.67 λl× 0. 13λl, at frequency of 25.25 GHz. The antenna consists of two rectangular slots (R1 and R2) in the radiating patch, which independently resonates at single band and quad band, respectively. The proposed antenna operates at 25.25, 27.97, 31.0 and 33.25GHz, with fractional bandwidth of at 0.71% (25.15-25.33GHz), 1.29% (27.74-28.1GHz), 1.03% (30.85-31.17GHz) and 1.63% (32.99-33.53GHz). Metallic switch placed in the middle of rectangular slot (R2) helps in achieving frequency reconfigurability. When the metallic switch is ON antenna resonates at single band and when the switch is OFF antenna resonates at quad band. The antenna evinces good impedance matching, gain and stable radiations characteristics across their operational bands.
