A driven quad antenna unit includes four perpendicularly arranged antenna elements, each element containing therein a high Q load coil in order to reduce the overall size of the antenna structure. A similarly configured parasitic loop unit functioning as a director or reflector (or both may be employed) is located in front or behind, as the case may be, the driven antenna unit. As with the driven unit, each side of the parasitic unit has a coil connected therein, the number of turns in each coil of the director being somewhat less than in the number in the coils of the driven unit and somewhat greater in the coils of the reflector.
