Abstract
This paper describes beam-tilting characteristics of horizontally polarized EMCD (electromagnetically coupled dipole) array antennas. The result of one element radiator is used for array elements designs and is evaluated its characteristics. Theoretical frequency characteristics and radiation pattern of the horizontally polarized EMCD array antennas analyzed by FDTD method agree well with the measured results of the practically fabricated way antennas. The measured main beam tilt ang1e and 3 dB beam width of the fabricated 20-element array antennas are 47$^{\circ}$and about $\pm$7.5$^{\circ}$, respectively. A good radiation pattern and beam tilting characteristics are observed in experiments.
