ABSTRACT:
A broadband omnidirectional antenna has a monopole element driven by an rf source at one end and a load at its other end consisting of insulated parallel conductors tuned to different resonant frequencies. The parallel conductors are equidistantly spaced so that transmission line coupling occurs between adjacent conductors. The parallel conductors progressively decrease in length the further away each conductor is supported from the driven element. The antenna elements can be fabricated from attached insulated wires or ribbon cable and thus the antenna can have low weight, little bulk and great flexibility.
