Abstract :
A modified annular sector radiating line antenna has been designed to improve the efficiency of the basic Anserlin antenna by introducing smooth or serrated annular rings around the antenna. Design curves generated for the modified Anserlin antenna are utilised to produce a four-element series-fed linear array with 18 dB sidelobe taper at 2.1 GHz without the need for an amplitude tapering network
