Abstract
ABSTRACT In this article, an antenna structure consisting fractal defected ground monopole antenna for circularly polarized radiation is presented. The characteristics of circular polarization in the proposed structure are obtained by fractal defected ground structure. The third iterative h-shaped fractal slot antenna is fabricated and examined on Rogers RT/duroid 5880 substrate for validating the simulated results. The best circular polarization radiation is obtained by varying the key parameters of the proposed geometry. The simulated and measured results confirmed that the proposed antenna can be adequately produced an impedance bandwidth (2.15 GHz – 3.55 GHz) of 49.12% with 3 dB axial ratio bandwidth (2.54 GHz – 3.03 GHz) of 17.59%, while the measured peak gain of the proposed structure is 2.99 dBic. The proposed work is suitable for Bluetooth/LTE/CNSS/S-band and CA-band 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.
