Utilization of double metal-dielectric composite substrates for microwave miniaturization of rectangular patch antennas

摘要

The microwave concept of miniaturization of a rectangular patch antenna using two-layer metal-dielectric composite substrate with a large value in the real part of the effective relative permittivity is developed. Each layer is a metamaterial slab in the form of a parallelepiped dielectric matrix with periodically embedded metallic wires. The proposed idea is validated by numerical simulations for sample rectangular patch antennas. The comparative analysis of the simulation results is made at the frequencies of approximately 15 GHz.
