Sammanfattning

In this talk we show some potential applications of a pair of conventional double positive (DPS) and single negative (SNG) metamaterial blocks for specific patch antennas. We propose two designs. One is a 900- and 1800-MHz dual-band rectangular patch antenna filled with a pair of juxtaposed DPS and mu-negative (MNG) metamaterial blocks. With proper constitutive parameters and filling ratio of the material blocks, the conventional TM020 mode is modified and broadside radiation pattern can be simultaneously achieved at both bands. The other is a two-layered rectangular patch antenna, with a bi-layer of DPS and epsilon-negative (ENG) metamaterial as its substrate. Due to the super-slow TM surface wave mode that the bi-layer structure supports, the size of the patch antenna is substantially reduced as compared to conventional λ/2 patch antennas.
