1. An antenna comprising:
a ground plane; a first radiating element mounted on said ground plane; a second radiating element mounted on said ground plane in spaced relation to said first radiating element, each one of said first and second radiating elements comprising:
a feed leg for feeding said radiating element;a ground leg for grounding said radiating element;a folded element having a first end and a second end, said first end being connected to said feed leg, said second end being capacitively coupled to said radiating element; anda supplementary ground connection extending between said feed leg and said ground plane, wherein each one of said first and second radiating elements comprises an upper radiative meandering portion distal from said ground plane, said feed and ground legs extending from said upper radiative meandering portion, wherein said upper radiative meandering portion comprises an angularly bent structure lying in a first plane and defining inner orthogonally angled corner portions, said angularly bent structure comprising a first and a second orthogonally angled outer corner and a third and a fourth beveled outer corner, a length of a bevel of said third beveled outer corner being greater than a length of a bevel of said fourth beveled outer corner, wherein said feed leg extends from an intermediate point along said angularly bent structure, said intermediate point being inset from said third beveled outer corner, said feed leg comprising a first elongate portion lying in a second plane, perpendicular to said first plane, said first elongate portion comprising an upper first stub portion proximal to said angularly bent structure and a lower bent segment proximal to said ground plane, and wherein said folded element comprises:
a second tapered portion extending from said lower bent segment and lying in a third plane, parallel to said first plane and perpendicular to said second plane, said second tapered portion comprising a circular terminal section;a third acutely angled portion extending from said circular terminal section;a fourth portion contiguous with said third acutely angled portion and bent in a direction away from said angularly bent structure, said fourth portion comprising an inverted arrow-like structure comprising a lower head segment having an apex contiguous with said third acutely angled portion and an upper stem segment having a beveled edge; anda fifth portion contiguous with said beveled edge and acutely bent with respect thereto, said fifth portion comprising an orthogonal corner portion and a perpendicularly bent tab, said perpendicularly bent tab terminating in a second open-ended stub portion and lying in a fourth plane, parallel to and offset from said first plane. |
