Abstract

Novelty of the proposed design lies in miniaturization of Rectangular Dielectric Resonator Antenna (RDRA). Secondly, all Global Navigation Satellite System (GNSS) five bands have been accumulated in single structure. Amalgamation of metamaterial (MM) ring resonator, split ring resonators (SRR), modified rectangular slot and Artificial Magnetic Conductor (AMC) backplane structure has been used to design proposed GNSS antenna. The frequency resonances obtained are narrow (large frequency ratio) and highly sensitive, thus impedance is perfectly matched for all five bands. The simulated results are closely matched with the measured results. High front to back ratio (FBR) obtained using novel MM AMC backplane. Gain enhancement of 5dBi obtained in GNSS antenna using AMC backplane structure. DRA miniaturization (98.6%) has been carried out using MM. The antenna results have been measured at L1 (1575.42 MHz/L2(1227.6 MHz)/L3(1381.05 MHz)/L4(1379.913 MHz) and L5 (1176.45 MHz) bands.

GNSS五波段小型化DRA的设计与实现

该设计的新颖之处在于矩形介质谐振器天线（RDRA）的小型化。其次，全球导航卫星系统（GNSS）的所有五个波段都积累在单一结构中。采用超材料环形谐振器（MM）、劈裂环形谐振器（SRR）、改进矩形槽和人工磁导体（AMC）背板组合结构设计了GNSS天线。获得的频率共振窄（大频率比）和高灵敏度，因此阻抗在所有五个波段都是完美匹配的。模拟结果与实测结果吻合较好。采用新型mmamc背板获得了高前后比（FBR）。采用AMC背板结构实现GNSS天线增益增强5dBi。在L1 (1575.42 MHz/L2(1227.6 MHz)/L3(1381.05 MHz)/L4（1379.913 MHz）和L5 （1176.45 MHz）频段测量了天线结果。
