Abstract

A compact, low-profile, coplanar waveguide (CPW)-fed quad-port multiple-input-multiple-output (MIMO)/diversity antenna with triple band-notched (Wi-MAX, WLAN, and X-band) characteristics is proposed for super-wideband (SWB) applications. The proposed design contains four similar truncated-semi-elliptical-self-complementary (TSESC) radiating patches, which are excited through tapered CPW feed lines. A complementary slot matching the radiating patch is introduced in the ground plane of the truncated semi-elliptical antenna element to obtain SWB. The designed MIMO/diversity antenna displays a bandwidth ratio of 31:1 and impedance bandwidth (|S| ≤ - 10 dB) of 1.3-40 GHz. In addition, a complementary split-ring resonator (CSRR) is implanted in the resonating patch to eliminate WLAN (5.5 GHz) and X-band (8.5 GHz) signals from SWB. Further, an L-shaped slit is used to remove Wi-MAX (3.5 GHz) band interferences. The MIMO antenna prototype is fabricated, and a good agreement is achieved between the simulated and experimental outcomes.

摘要

提出了一种用于超宽带（SWB）应用的紧凑型、低剖面、共面波导（CPW）馈电四端口多输入多输出（MIMO）/分集天线，具有三频带阻（Wi-MAX、WLAN 和 X 波段）特性。该设计包含四个相似的截断半椭圆自互补（TSESC）辐射贴片，通过锥形 CPW 馈电线激励。在截断半椭圆天线元件的接地平面中引入与辐射贴片匹配的互补槽，以获得 SWB。设计的 MIMO/分集天线显示带宽比为 31:1，阻抗带宽（|S|≤-10dB）为 1.3-40GHz。此外，在谐振贴片中植入互补分裂环谐振器（CSRR），以消除 SWB 中的 WLAN（5.5GHz）和 X 波段（8.5GHz）信号。进一步，使用 L 形缝隙去除 Wi-MAX（3.5GHz）频段干扰。制造了 MIMO 天线原型，模拟和实验结果之间具有良好的一致性。
