Simulation Methodology for Synthesis of Antenna Substrates With Microscale Inclusions

Microstrip patch antennas on substrates with metallic inclusions

“…The and are passed through the "Inverse Scattering Formalism" after a phase rectification process [23] from which the effective permittivity, and permeability, are extracted. Further details can be found in [11]. One layer of cubes (equal to unit cell size) is 0.5 mm.…”

“…These bespoke materials can be integrated to form complete antennas systems where the metallic and dielectric elements are made in one process, resulting in time and potential cost savings [11], [12], [13].…”

“…A small size, high efficiency antenna can be achieved by using an as yet unrealizable material with equality of permittivity and permeability [20]. An initial study by the authors gave preliminary insight into the behaviour of patch antennas on synthetic media with dielectric inclusions [11], [21].…”

Composite materials for microwave devices using additive manufacturing

“…The relative permittivity of the composite materials was measured by fabricating patch antennas using these materials as the substrate. It has been demonstrated that by using Taconic, PLA and air, three materials with different dielectric constants, a large and nearly continuous range of relative permittivity values, from 1.47 to 6.00, can be realised.Introduction: Materials whose relative permittivity can be controlled by the designer have the potential to be employed as antenna substrates and can enhance antenna performance [1]. Such materials are also an integral part of graded index (GRIN) devices.…”
