摘要
An antenna element employable singularly or in an array and configured for concurrent RF transmission and receipt on a plurality of frequencies concurrently. The element is formed of conductive material on a substrate by a pair of substantially identical horns extending in opposite directions to distal tips. A cavity formed between the horns narrows to a narrowest point prior to curving. The element is capable of wideband RF communication on any frequency between a low frequency defined by the distance between the distal tips to a highest frequency defined by the narrowest point of the cavity. The antenna is especially well adapted for portable devices such as smartphones where concurrent cellular, Wi-Fi, and bluetooth communications may be accomplished with a single element. A dielectric planar substrate positioned between the antenna element and a tethered device is employable to reduce a spacing requirement therebetween.
