Toward a new generation of miniature multifrequency antennas using multiresonance platform based on subwavelength structures inspired by advanced metamaterials
Demand in miniature antennas has been growing over the last decades. A variety of modern applications like implantable antennas, miniature wireless sensors, internet-of-things (IoT) and multifunctional communication systems have stimulated this process. Development of miniature antennas for multiband operation is a trend in mobile communications. A modern smartphone has several functions that need several antennas in one device, to be used for WiFi, GPS, cellular network bands, etc., while its acceptable size is strongly restricted. One multiband antenna instead of many single-band antennas in one device is a good option, but size issues remain critical. Inexpensive small antennas which are well integrated with the other electronics are needed by the industry. The overall objective of this project is to build a framework containing theoretical bases and efficient design procedures for miniature multiband antennas that may support multiple legacy communication standards. It is achieved by utilizing the specific properties of subwavelength resonators and planar metamaterials (metasurfaces) on their basis. The multiresonance concept and quantification of the scaling of resonance frequencies have been introduced to enable systematic design of multiband antennas. This allows us to fully exploit the advantages of the common miniaturizing effect of subwavelength resonators and a very-high-permittivity substrate to yield an alternative to commercial ceramic antennas. Design solutions for conventional substrates have been proposed for a large number of the subwavelength bands. Our theoretical framework has been experimentally proved for the designed compact antennas on a conventional substrate and ultra-miniature antennas on a very-high-permittivity substrate. It was applied to design antennas with two to six simultaneous operation bands in the frequency range from 0.8GHz to 10GHz, in order to enable cost-efficient solutions for the present and future needs of communication systems. A study of metasurfaces and related structures of the selected types has been performed to find the routes to further advancements and new scenarios of radiation manipulation.

Project objective
Mobile multiservice communication devices are constantly used in people’s daily life with ever increasing demand for cost effective, multiband and smaller antennas. The planned research is dedicated to development of a theoretical basis and a design approach for a new generation of miniature multifrequency antennas enabling up to ten various services at 0.8GHz to 10GHz simultaneously. This multiresonance antenna platform will be realized with the aid of subwavelength multiresonator structures where the individual resonators represent unit cells of the specially designed metamaterials (MTMs). The project has a pronounced interdisciplinary nature by merging antenna theory, material science, advanced modelling and design for manufacturability as well as measurements. Two new applied theoretical frameworks will be developed for (i) scaling subwavelength resonances and (ii) connection of characteristics of radiation and MTM cells. They will be utilized for design of miniature multifrequency antenna systems with up to tenfold difference between operation frequencies. Proof of concept will be done for monopole/dipole type antennas and then transferred to patch antennas. Thus, a route to a new generation of multifrequency antenna systems will be found, creating a practical development framework for the demanded innovation in multifunctional communication systems. The mobility will give the researcher an opportunity to acquire new knowledge in applied antenna design and assessment. With his recognized theoretical background and proficiency in novel materials applied for antennas, the career development towards a leading position inside or outside academia will be fulfilled. An extensive mutual transfer of knowledge will be beneficial for both the researcher and the host institute. The project will inspire novel utility mobile and wearable devices, which will improve the overall quality of life and enhance competitiveness of the EU industry.
