Abstract

An ultra-wideband antenna 10, or a method of making it, comprises a first laminar dielectric substrate 14 with a transmission element formed on a first planar surface of the substrate. The transmission element comprises a radiating element 12 which is tapered towards a narrow end which is connected to a first end of a transmission line 19. The distal, wider end, of the radiating element 12 has a v-shaped notch defining two diverging lobes where the outer edges 21 of the lobes have serrations 17. The second end of the transmission line 19 is connected to a signal connection point 15 and the transmission line is surrounded and spaced from a coplanar ground element 27. The second planar surface of the said substrate 14 is coupled to a first surface of a second laminar dielectric substrate 52 which has a plurality of conductive elements 54 on its first surface which are electrically connected through the dielectric material to a ground plane covering the second surface of the second substrate 52. The conductive elements 54 on the first surface of the second substrate may be of a regular or irregular size, shape or pattern. The second dielectric substrate and its conductive elements provide a photonic circuit element or an artificial magnetic conductor AMC or high impedance surface which is an effective radio frequency reflector such that the compact antenna provides substantially unidirectional radiation.
