The phased circular array antenna of crossed-loop elements is a small-sized transportable high frequency wide band multibeam receiving antenna with operation band at 3 to 30MHz. Its reception performance is equivalent to twenty or thirty rhombic antennas, as a number of independent directional wave beams can be introduced by Phasing networks. Moreover, it only requires just one tenth of the space for rhombic antenna, because vertical loop element used will not require great installation height, thus...

The phased circular array antenna of crossed-loop elements is a small-sized transportable high frequency wide band multibeam receiving antenna with operation band at 3 to 30MHz. Its reception performance is equivalent to twenty or thirty rhombic antennas, as a number of independent directional wave beams can be introduced by Phasing networks. Moreover, it only requires just one tenth of the space for rhombic antenna, because vertical loop element used will not require great installation height, thus reducing first Fresnel region to form a low-elevation main lobe.The paper discusses following theoretical aspects of the said antenna: far-zone radiation field, a direction-controlled weighting factor for crossed-loop element radiation pattern, the dual-direction properties, space radiation patterns, structure of central phasing networks to form multi-directional beams and the mutual coupling problem between array elements.
