Abstract

A 1 × 4 antenna array facilitated by an innovative electrically small Huygens dipole element is reported. The entire array is ultra-thin, being realized on a single PCB substrate. Each of the Huygens linearly-polarized (HLP) dipole elements is the result of a careful integration of one pair of metamaterial-inspired electrically small structures, i.e., an Egyptian axe dipole (EAD) and a capacitively loaded loop (CLL) near-field resonant parasitic (NFRP) element. The EAD acts as the electric dipole radiator; the CLL works as the magnetic dipole radiator. They are oriented orthogonal to each other and are in-phase to radiate identical cardioid-shaped Huygens patterns in both the E- and H-planes. The consequent 1 × 4 Huygens array operates at 2.45 GHz with a high 8.9 dBi peak realized gain. It has a narrow E-plane 3-dB beamwidth, 28°, and a very broad H-plane beamwidth, 153°. The developed linear HLP-based array is particularly useful for far-field wireless power transfer (WPT) enabled IoT applications that require broad area coverage.
