Abstract: An antenna assembly including flexible antenna elements connected to a non-flexible antenna element which connects to a counterpoise where the non-flexible antenna element is between the counterpoise and the flexible antenna elements. The flexible antenna elements are a plurality of peripheral flexible antenna elements and a central flexible antenna element. The plurality of peripheral flexible antenna elements are separated from and surrounding the central flexible antenna element. The non-flexible antenna element is a biconical antenna, formed from two tapered shapes connected at a central feed point such that a constant electrical impedance as the currents radiate outward from the central feed point. A total length of the flexible antenna elements connected to the non-flexible antenna element is ?43.0 cm, and the flexible antenna elements connected to the non-flexible antenna element has a realized gain of at least 2 dB over at least a frequency range of 200-7000 MHz.

Abstract: An antenna includes a dielectric substrate having a planar shape. The dielectric substrate has a first side and a second side. An elongated feed is disposed on the first side of the substrate. A ground plane is disposed adjacent to and spaced apart from the feed on the first side of the substrate. A meander has a first end coupled to the elongated feed. The meander comprises a second end disposed opposite the first end. A first extension extends from the second end adjacent to the meander. A second extension extends from the second end adjacent to the meander.
