超宽带实用型介质谐振器天线研究与设计
Research and design of practical UWB DRA
摘要
Abstract
In order to reduce the system complexity,the modern wireless communication technology has high requirement for the performance of the single antenna bandwidth,therefore a practical UWB dielectric resonator antenna (DRA) was re-searched and designed. The microstrip line slot coupled feeding mode is adopted for the antenna. The feeding was performed for the rectangular slot and U-shaped slot in the earthing plate through the antenna. The current is input into the dielectric resonator through the slots. In order to prevent the scattering of electromagnetic wave,the parasitic patch is attached on the back of the di-electric resonator. The reflection plate is added on the top of the dielectric resonator to improve the performance of the antenna greatly. The antenna is resonated at 5.25 GHz and 6.3 GHz respectively,works at 4.6-6.8 GHz (5.1~5.9 GHz is the WLAN band),its impedance bandwidth can reach up to 39%,and has perfect practical value. The simulation results of the antenna were obtained by means of the electromagnetic simulation software. The Agilent Technology PNA N5245A vector network analysis meter is used to measure the return loss and gain of the antenna. The obtained measured results are close to the simulation results.关键词
