摘要： A fabric antenna for telecommunications is disclosed. The fabric antenna comprises a host yarn, which is substantially electrically non-conducting, and an antenna yarn, which is substantially electrically conducting. The host yarn and antenna yarn are knitted together to form a host fabric comprising an antenna grid. The antenna grid comprises a plurality of intersecting antenna tracks formed of antenna yarn. The tracks are separated by regions of the host fabric and are electrically coupled together at the regions where the tracks intersect.

摘要： A method of manufacturing and an antenna having an upper and lower loop. Upper loop comprising a first conductive loop defined by an upper conductor and a first conductive blade tapering outwardly to form a flare portion adjacent a distal end of the upper conductor. Lower loop comprising a second conductive loop defined by a base conductor and a second conductive blade tapering outwardly forming a flare portion adjacent a distal end of the base conductor. First and second conductive blades defining, between their facing edges, a notch opening outwardly from a feed region. Upper loop further comprising an elongate conductive vane extending at an angle from a first location on the upper conductor to a second location on the first conductive blade defining a pair of loops within the upper loop.

摘要： A wide band antenna comprising a signal generator coupled to a feed region of at least one antenna element comprising upper and lower loops. Upper loop comprising a first conductive loop element defined by an upper conductor and a first conductive blade tapering outwardly forming a flare portion adjacent a distal end of the upper conductor. Lower loop comprising a second loop defined by a base conductor and a second conductive blade tapering outwardly forming a flare portion adjacent a distal end of the base conductor, first and second conductive blades defining, between their facing edges, a notch opening outwardly from feed region. The method comprising matching an antenna element impedance to the transmission line; selecting an antenna element cut-off frequency; selecting an upper conductor length, and subsequently selecting dimensions of the upper loop such that they are substantially equal to a wavelength corresponding to the selected cut-off frequency.
