THIN FREQUENCY-SELECTIVE LATTICES INTEGRATED IN NOVEL COMPACT MIG, MMIC, AND PCA ARCHITECTURES

We analyze and optimize the design of novel composite materials for IC 's and printed circuit antenna (PCA) applications. We are using a vari ety of finite artificial lattices (FAL's) carrying passive metalo-diel ectric unit cells. We first examine and optimize these lattices as fre estanding structures, regarding them as FSS's and space filters. We ob tain several designs for appropriate metalo-dielectric unit cells, as well as stacking geometries for constructing thin laterally infinite a rtificial lattices. Further, we examine the action of the correspondin g FAL within integrated architectures, emphasizing crosstalk suppressi on, circuit-coupling tailoring, and gain enhancement. We find very sig nificant directive gain enhancements for compact packaged PCA applicat ions. Finally, anomalous scaling of the resulting circuits and tunable designs are also presented.
