Abstract:
1. An antenna comprising: a grounding element extending along a first plane; a radiating element having a first side and extending along a second plane substantially parallel to said first plane, said radiating element being aligned with said grounding element in a normal direction transverse to the first and second planes, wherein said radiating element further has a second side that is opposite to said first side in a first direction transverse to the normal direction, said grounding element further having a second side opposite to said first side of said grounding element and flush with said second side of said radiating element, wherein said grounding element has a first side substantially flush with said first side of said radiating element; a bridging element interconnecting said grounding and radiating elements, said bridging element extending from said second side of said radiating element to said second side of said grounding element, wherein said bridging element is trapezoid in shape, and is tapered from said grounding element to said second side of said radiating element; and a feeding element extending and tapered from said first side of said radiating element toward said grounding element, wherein said feeding element has a first end that is connected to said first side of said radiating element, and a second end that is opposite to said first end in the normal direction said feeding element further having a stub protrusion protruding from said second end of said feeding element toward said grounding element, said second end of said feeding element being flush with and being spaced apart from said first side of said grounding element in the normal direction by a distance that is less than the distance between said first and second ends of said feeding element.
