Latest Patents

Xun Liu holds a patent for "Dielectric resonator antenna arrays." This invention involves arrays of low permittivity polymer-based resonator antenna elements with various configurations. The individual array elements can be fabricated with complex geometries, allowing for the assembly of intricate patterns as a single monolithic structure. This design eliminates the need for separate positioning and assembly of array elements. The monolithic array structures can also be combined into larger array configurations. The elements, sub-arrays, and arrays can be formed by inserting dielectric materials into cavities that define their lateral geometries, and they can be fabricated using polymer templates. These templates can either be removed or retained as part of the antenna. Effective excitation is achieved through various coupling methods, including standing metal strip feeding, tall metal transmission lines, modified microstrip feeding, or aperture feeding using a slot in the metal plane beneath the elements. The wideband array feeds are realized through optimized transmission line distribution networks that include wideband matching sections. Xun Liu has 1 patent to his name.
