Patent number: 10784583Abstract: Arrays of low permittivity Polymer-based Resonator Antenna elements with different configurations. Individual array elements can be fabricated with complicated geometries; these elements can be assembled into complicated patterns as a single monolithic fabricated structure using narrow wall connecting structures, which removes the requirement to position and assemble the array elements. Monolithic array structures can be assembled as sub-arrays in larger array structures. Elements, sub-arrays, and arrays can also be formed by inserting dielectric materials into cavities defining their lateral geometries, and fabricated in polymer templates. The polymer templates can be removed or retained to function as part of the antenna.Type: GrantFiled: December 19, 2014Date of Patent: September 22, 2020Assignee: University of SaskatchewanInventors: Mohammadreza Tayfeh Aligodarz, David Klymyshyn, Atabak Rashidian, Xun Liu

Publication number: 20150303546Abstract: A new class of antennas and microwave components are introduced. In this approach a high-permittivity dielectric film is applied (i.e. printed) on a dielectric substrate, which may be grounded. By changing the shape of the high-permittivity film, different microwave devices (e.g. waveguides, filters, couplers, and antennas) are produced. By changing the size and permittivity of the high-permittivity film and dielectric substrate, these elements are designed at different frequencies for different applications. Highly-efficient microwave devices can result due to the absence of surface currents.Type: ApplicationFiled: June 21, 2013Publication date: October 22, 2015Applicants: The University of Manitoba, The University of SaskatchewanInventors: Atabak Rashidian, Lotfollah Shafai, David M.
