Dual-band isotropic radiation patterns from a printed electrically small loop-loaded dipole antenna

摘要

A printed electrically small loop-loaded dipole antenna is upgraded to radiate dual-band isotropic patterns with compelling compactness. The proposed technique can be easily extended for multi-band or reconfigurable designs. Simulation of a 0.1lambda antenna shows peak deviations of radiation power density pattern in the full space are below 4.0 dB for both bands.
