Abstract :
A new annular ring microstrip patch resonator with reduced size is proposed. The underlying material is partially occupied by a ring of metamaterial with negative permittivity and permeability. It is shown that the resonant frequency of the TM/sub 110/ cavity mode can be made as small as we desire by proper choice of dimensions and material parameters. Relevance to the design of compact patch antennas for wireless receivers is indicated.
