Artificial magnetic materials (AMMs) are used as a substrate in design of miniaturized low profile antennas. We demonstrate the design of a microstrip patch antenna on a substrate composed of Rose curve resonators (RCRs). The RCR, a novel rose shape broken metallic inclusion, is a generic inclusion for design of an AMM with desired properties. It is shown that an AMM composed of RCRs allows the design of a patch antenna operating at desired frequency while occupying specific dimensions. In fact, the proposed substrate enables design of highly miniaturized low profile antennas. A prototype patch antenna is designed and fabricated, and its performance is compared with counterpart designs in the literature.
