A compact ultra-wideband Multiple-Input-Multiple Output (MIMO) Monopole antenna is proposed for frequency-notched applications. The proposed MIMO antenna consists of two identical Monopole antennas excited by two microstrip feeds. A stub is attached to the ground plane to improve isolation and impedance bandwidth. A quarter wavelength spur line is embedded on the feeding part of the antenna to achieve the notch frequency. The designed antenna exhibits −10 dB impedance bandwidth, covering the entire UWB spectrum. The L-shaped spur line contributes to the notch frequency at 5.5 GHz aiming to avoid interference from 5 to 6 GHz WLAN band. The planned model is fabricated and described in terms of impedance and radiation constraint measurements, compliant with those of results achieved from full wave simulation.

提出了一种用于频率陷波应用的紧凑型超宽带多输入多输出（MIMO）单极天线。所提出的 MIMO 天线由两个相同的单极天线组成，由两个微带馈源激励。短截线连接到接地层以改善隔离和阻抗带宽。天线馈电部分嵌入四分之一波长支线以实现陷波频率。设计的天线具有−10 dB 阻抗带宽，覆盖整个 UWB 频谱。L 形支线有助于 5.5 GHz 的陷波频率，旨在避免 5 至 6 GHz WLAN 频段的干扰。所计划的模型是根据阻抗和辐射约束测量来制造和描述的，与全波仿真所获得的结果一致。
