Linear to circular polarized wave convertor loaded dual port dielectric resonator antenna with enhanced gain for WLAN applications
In this article, a dual-port ceramic-based radiator is discussed and examined. A pentagon-shaped slot is used to excite the cylindrical-shaped dielectric, which stimulates HEM11δ mode in it. A meta-surface is placed over the dual-port radiator for transforming linear waves into circularly polarized (CP) waves from 5.51 to 6.01 GHz. LHCP antenna gain is also increased from 6.0 to 9.0 dBi within the working frequency range, after applying the proposed meta-surface. Experimental verification of antenna prototype confirms the working band of the proposed radiator from 5.25 to 6.17 GHz. The isolation between the ports is more than 20 dB, which is in the acceptable limit. The better value of far-field and diversity factors confirms the suitability of the proposed antenna in wireless LAN (5.5 GHz) applications.
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.
