Abstract

A compact Ultra-Wide Band (UWB) antenna with a wide-band reject notch at C-band and X-band is presented for applying in wireless communication systems. The designed structure is printed on a material of “ Rogers 4350B” with εr = 3.66, tanδ, = 0.0037 and a thickness of 0.508 mm. This structure is designed to operate at an ultra-wide band range starting from 3.3GHz up to 10.15GHz with a stop-band range from 6.75GHz to 8.5GHz. The dismissal bands are the upper C-band (6.75GHz – 8GHz) and the uplink X-band of the satellite (space to earth) from 7.25GHz to 7.75GHz. The overall antenna size is optimized and its dimensions are 21 x 30 x 0.508 mm3. The antenna gain varies from 2.1 to 4.2dBi” at the pass band and its total radiation efficiency is 96.4%. The suggested structure is designed and simulated using CSTMWS software. Additionally, a prototype of the proposed structure is fabricated and measured. The fabrication process was done using photolithography techniques and the measurements was done using R&S vector network analyzer. The results from the simulation and the measurement are in good agreement.

一种用于无线通信系统的带缺口带的印刷单极宽带天线

提出了一种适用于无线通信系统的具有c波段和x波段宽带抑制陷波的小型超宽带(UWB)天线。所设计的结构打印在εr = 3.66, tanδ = 0.0037，厚度为0.508 mm的“Rogers 450b”材料上。该结构设计用于在3.3GHz至10.15GHz的超宽带范围内工作，其阻带范围为6.75GHz至8.5GHz。发射频段为卫星上c波段(6.75GHz ~ 8GHz)和上行x波段(空间对地)7.25GHz ~ 7.75GHz。天线整体尺寸优化，尺寸为21 × 30 × 0.508 mm3。该天线通频带增益为2.1 ~ 4.2dBi”，总辐射效率为96.4%。采用CSTMWS软件对建议的结构进行了设计和仿真。此外，还制作并测量了所提出结构的原型。制作过程采用光刻技术，测量使用R&S矢量网络分析仪完成。仿真结果与实测结果吻合较好。
