Abstract

A dual-linearly-polarized, electrically small, low-profile, broadside radiating Huygens dipole antenna is presented that is an advanced combination of electric and magnetic near-field resonant parasitic (NFRP) elements. Its prototype was fabricated and tested. The measured results are in good agreement with their simulated values. At 1.515 GHz the prototype is electrically small (ka = 0.904) and low profile (0.0483λ0). It exhibits high port isolation and a large front-to-back ratio (FTBR). The isolation between its two ports is demonstrated to be over 25.8 dB within its -10-dB fractional impedance bandwidth (FBW), 0.46%. When port 1 (port 2) is excited, the peak realized gain is 2.03 dBi (2.15 dBi) strictly along the broadside direction with a 12.4 dB (12.1 dB) FTBR.
