    • An antenna is provided which exhibits a low profile. The antenna includes a counterpoise of electrically conductive material and a passive element oriented substantially parallel thereto. The ends of the passive element are electrically coupled to the counterpoise surface. An active element of electrically conductive material includes a middle portion and first and second outer end portions. The middle portion is situated adjacent and spaced apart from the passive element by a predetermined distance and in a parallel relationship therewith. The first outer end portion of the active element is bent toward the grounded end of the passive element nearest thereto. The first outer end portion represents a feedpoint of the antenna with respect to the counterpoise. The remaining second outer end portion the active element is bent towards the remaining end of the passive element nearest thereto. The first and second outer portions by virtue of the bends which orient them close to the ends of the passive element result in coupling of substantial electromagnetic energy between the active element and a passive element. Substantial electromagnetic energy is radiated with both horizontal polarization and vertical polarization when the antenna is excited.

    • An antenna (100) includes a quarter-wave monopole radiating element (110, 110') having a signal feed point end (110A). The antenna (100) further includes a reactive element (150) in the form of a conductive sleeve. The sleeve (150) includes a grounding end (150A) and is coaxially positioned around a portion of the monopole radiating element (110, 110'). A spacer (140) is coaxially situated between the monopole radiating element (110, 110') and the reactive element (150), for electrically insulating the monopole radiating element (110, 110') from the reactive element (150). The spacer (140) is sufficiently dimensioned such that the monopole radiating element is tightly coupled to the reactive element (150) at substantially around the feed point end (150A).
