The Perspective of Magneto-Electric Dipole Antennas (eBook)

Document from the year 2021 in the subject Engineering - Communication Technology, grade: A, Manipal University, language: English, abstract: This book presents the proposal for the novel designs of the wideband Magneto-Electric (ME) dipole antenna for various applications in wireless communication. The standard ME dipole consists of a planar dipole, which acts like an electric dipole, and a vertically oriented quarter wave shorted patch, equivalent to a magnetic dipole. The research demonstrates the good electrical characteristics for the proposed designs of the wideband ME dipole antenna and shows low cross-polarization radiations, stable antenna gain across the operating frequency band and almost identical radiation patterns in the E- plane and H-plane. Literature confirms the design of the ME dipole antenna as linearly polarized, circularly polarized or differentially fed antenna and this thesis presents five novel structures of ME dipole antenna for applications like airborne radar, Ultra-Wide Band (UWB), mobile communication and satellite communication. After examining a number of feeding techniques designed to enhance the impedance bandwidth of ME dipole antenna, which includes co-axial-to-patch probe feeding, transition of microstrip-to-parallel strip line feeding, differential feeding, the book presents all the novel designs using co-axial probe feeding.
