Abstract

A multiband wide slotted antenna with Hilbert fractal slot on rectangular patch is presented. By using a wide slotted structure, a Hilbert fractal slot with 1st iterations in rectangular patch and microstrip fed line used as additional resonators producing multi-resonant frequencies for covering the wireless communication operations are developed. The results show good multiband operation with -10 dB impedance bandwidths of 22.22%, 17.22% and 9.58% at the frequency range of 0.87 - 0.96 GHz, 1.710 - 1.88 GHz, and 2.4 - 2.485 GHz, respectively. Finally, the presented antenna can operate and cover the applications of GSM, DCS, and Wireless Local Area Network WLAN IEEE802.11 b/g. Moreover, the antenna gains at operating frequencies of 0.9 GHz, 1.8 GHz, and 2.4 GHz are 2.84, 2.14, and 1.37 dBi, respectively. Especially, the antenna radiation patterns are almost the bi-directional at all of operating frequencies.

矩形贴片上具有希尔伯特分形缝隙的多频带宽缝隙天线

提出了一种矩形贴片上具有希尔伯特分形缝隙的多频带宽缝隙天线。采用宽槽结构，设计了一种具有矩形贴片和微带馈线第一次迭代的希尔伯特分形槽作为附加谐振器，产生多谐振频率，用于覆盖无线通信操作。结果表明，在0.87 ~ 0.96 GHz、1.710 ~ 1.88 GHz和2.4 ~ 2.485 GHz频率范围内，-10 dB阻抗带宽分别为22.22%、17.22%和9.58%，具有良好的多频段工作性能。最后，该天线能够工作并覆盖GSM、DCS和无线局域网WLAN IEEE802.11 b/g的应用。在0.9 GHz、1.8 GHz和2.4 GHz工作频率下，天线增益分别为2.84、2.14和1.37 dBi。特别是在所有工作频率下，天线的辐射方向图几乎都是双向的。
