摘要: 现代天线需要在多个谐振频率下工作,以满足最新通信技术进展需要。提出了一种基于开口谐振环的三角形多波段天线,利用频率选择表面提高了天线性能。天线在S、C和X波段有多次谐振。排列成4×3的十字形单元栅格阵列形成频率选择表面层。天线馈电采用微带馈线技术。该天线在3.5 GHz、4.1 GHz、5.5 GHz、9.4 GHz和9.8 GHz工作时,具有较好的回波损耗和增益。仿真结果与实测结果吻合良好。

Abstract: Today’s antennas have to operate in multiple resonant frequencies to satisfy the need of recent advances in communication technologies. This paper presents split ring resonator based triangular multiband antenna whose antenna performance is enhanced with the help of frequency selective surfaces (FSSs). The antenna has multiple resonances at S, C, and X bands. An array of 4 × 3 crisscross-shaped unit cells are arranged to form the FSS layer. The antenna is fed with a microstrip line feeding technique. The proposed antenna operates at 3.5 GHz, 4.1 GHz, 5.5 GHz, 9.4 GHz, and 9.8 GHz with a better return loss and gain. Simulated and measured results yield a good match.

Key words: triangular microstrip antenna, split ring resonator, frequency selective surface (FSS), metamaterial
