ABSTRACT:
A notch antenna (10) has a metallic notch element (20) deposited on a dielectric substrate (12), which element has a smooth continuously curved edge located adjacent a substrate edge (18). A metallic ground plane (28) is located adjacent the substrate edge (18) spaced very closely to element 20 at one end and at a gradually increased spacing moving away from the one end. An electromagnetic field transmitting coaxial cable (30) with ferrite beads (44) received over its outer conductor for reducing spurious radiation is located on the opposite side of substrate (12,14). The cable center conductor (34) is connected to a metallic strip (38) that is located on the same side of substrate (12,14) as the coaxial cable and tracks the same path as the notch element (20) on the opposite side of substrate (12). The antenna (10) is fed by electromagnetic energy at the closely spaced region of the element (20) and ground plane (28).
