Analysis of the resonance response improvement of a planar C-band (4-8 GHz) antenna is proposed using parasitic element method. This parasitic element based method is validated for change in the active and parasitic antenna elements. A novel dual-band antenna for C-band application covering 5.7 GHz and 7.6 GHz is designed and fabricated. The antenna is composed of circular parasitic element wit...

Electronic circuits inevitably involve reactive elements, in some cases intentionally but always at least as significant parasitic elements. Although their influence on circuit performance may be subordinate for a particular circuit reactive elements introduce an ultimate limitation on frequency response and switching speed. Energy storage in a reactive element is a reflection of the prior acti...

Abstract: This paper describes the development and the realization of an adaptive antenna based on a reconfigurable parasitic structure. The geometry of the proposed antenna is circular, and it is composed by an active omni-directional radiator, surrounded by a number of parasitic elements that can be optically activated and configured as a director or as a reflector. The optical switches are a...

In this paper, a high frequency contactless power transfer (CPT) system is designed with ∅2 inverter drive. This system works in 30MHz frequency and 380W power with low voltage stress and considers the inductive link parasitic capacitor effect. In the design, we formulated the inverter equations first and then suggested another design for the transmitter and the receiver coils as the energy tra...

Interspersed repeats are a major component of most eukaryotic genomes and have an impact on genome size and stability, but the repetitive element landscape of crocodilian genomes has not yet been fully investigated. In this report, we provide the first detailed characterization of an interspersed repeat element in any crocodilian genome. Chompy is a putative miniature inverted-repeat transposab...
