University of Bristol PhD student and Flann Microwave RF engineer Oliver James attended this year’s European Conference on Antennas and Propagation in London (EuCAP2018) to present his work on the use of magneto-dielectric materials for use in antenna miniaturisation.
Oliver said: “These materials are interesting because they can be used to help reduce the physical size of antennas while offering frequency reconfigurability to address multi-band service in a compact terminal. While the materials are generating much research interest for use in antennas, reports of actual measured performance under radiative test conditions are nearly non-existent. The work conducted here aimed to rectify the shortfall by designing and testing the performance of a magneto-dielectric antenna with a view to frequency-reconfigurable deployment in the UHF band.”
The paper, “Hexaferrite substrate versus impedance matching for tuneable patch antenna miniaturisation” will appear in the EuCAP conference proceedings as published in the IET Inspec and IEEE Xplore digital libraries. Oliver’s work was conducted at the University of Bristol’s Centre for Doctoral Training in Communications and financially supported by the Engineering and Physical Sciences Research Council (EPSRC) and the University of Bristol.
