Abstract

Two electrically small, dual-band Huygens dipole antennas are reported. In both designs, two pairs of magnetic and electric near-field resonant parasitic (NFRP) elements are combined organically within an electrically small, low profile package. The NFPR elements are excited effectively using only one coaxial-fed driven element. One dual-band Huygens system produces parallel, linearly polarized (LP) fields at its two operating frequencies. The other dual-band system produces two orthogonal LP fields. Additional parasitic elements are introduced to mitigate the mutual coupling effects between the pairs of NFRP elements. The measured values for prototypes of both antennas in the L-band demonstrate their electrically small size (ka<1) and low profile (~0.03λ0). They also confirm their broadside radiation and polarization performance characteristics, as well as the isolation between each operating frequency. Their fractional bandwidths, peak realized gains, front-to-back ratios (FTBR), and radiation efficiencies (RE) are, respectively, ~ 0.6%, > 2 dBi, > 10 dB, and > 60% at both frequencies. These dual-band systems would provide multi-functional performance in a variety of portable, compact wireless devices.
