Abstract (en)

A method of manufacturing a wide band antenna comprising a signal generator coupled, via a transmission line, to a feed region (7) of at least one antenna element comprising an upper loop (1) and a lower loop (3), said upper loop (1) comprising a first conductive loop element (2) defined by an upper conductor (9) and a first conductive blade member (10) that tapers outwardly to form a flare portion (11) adjacent a distal end of said upper conductor (9), said lower loop (3) comprising a second conductive loop element (4) defined by a base conductor (5) and a second conductive blade member (6) that tapers outwardly to form a flare portion (8) adjacent a distal end of said base conductor (5), said first and second conductive blade members (10, 6) defining, between their facing edges, a notch which opens outwardly from said feed region (7), the method comprising the steps of: matching, at a desired operating frequency range, an impedance of said antenna element to said transmission line; selecting a cut-off frequency of said antenna element; selecting the length of the upper conductor (9) according to said selected cut-off frequency; and, subsequently selecting the remaining peripheral dimensions of the upper loop such that, combined, they are substantially equal to a wavelength corresponding to the selected cut-off frequency.
