摘要

摘要本文展示了一种具有多频带配置的紧凑型可重构微带天线。它在三种不同的频率配置下产生谐振，包括单频段和双频段。主矩形贴片天线适用于WLAN（5.2GHz中心频率）频带。馈线附近的可重构电磁带隙（EBG）和寄生贴片产生4和6.33GHz的谐振。将缺陷接地结构与PIN二极管集成，制成可重构EBG，并在C波段（4GHz）谐振。嵌入EBG和一个方形贴片的PIN二极管开关配置在无线局域网（WLAN）和国际电信联盟（ITU）频带中创建双频带特性。具有主天线和两个其他贴片的其他PIN二极管切换配置适用于C和WLAN频段。所提出的天线在4、5.2和6.33GHz频率下与PIN二极管的不同开关配置谐振。还给出了这种新型天线配置的仿真结果，并对反射系数和辐射特性等天线参数进行了测量。

Multi-band frequency reconfigurable antenna using EBG and parasitic patches

ABSTRACT This article demonstrated a compact reconfigurable microstrip antenna with a multi-band configuration. It resonates for three different frequency configurations, including the single and dual bands. The primary rectangular patch antenna resonates for WLAN (5.2 GHz center frequency) band. The reconfigurable electromagnetic bandgap (EBG) and parasitic patches near the feed line produce 4 and 6.33 GHz resonance. The defected ground structure is integrated with a PIN diode to make reconfigurable EBG, and it resonated at C band (4 GHz). The PIN diode switching configuration embedded with EBG and one square patch creates dual-band characteristics in wireless local-area network (WLAN) and International Telecommunication Union (ITU) bands. Other PIN diodes switching configurations with primary antenna and two other patches work for C and WLAN bands. The proposed antenna resonated at 4, 5.2, and 6.33 GHz frequencies with different switching configurations of the PIN diode. The simulated results of this novel antenna configuration verified with measured consequences for antenna parameters like reflection coefficient and radiation characteristics are also presented.

期刊介绍： Publishing eight times per year, Electromagnetics offers refereed papers that span the entire broad field of electromagnetics and serves as an exceptional reference source of permanent archival value. Included in this wide ranging scope of materials are developments in electromagnetic theory, high frequency techniques, antennas and randomes, arrays, numerical techniques, scattering and diffraction, materials, and printed circuits. The journal also serves as a forum for deliberations on innovations in the field. Additionally, special issues give more in-depth coverage to topics of immediate importance. All submitted manuscripts are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. Submissions can be made via email or postal mail.
