Abstract
On respective ground conductor plate surfaces, first and second dielectric substrates are formed. First and second antenna elements made of a conductor film of a rectangular cooper leaf or the like are formed on opposite surfaces of the first and second dielectric substrates to the ground conductor plate. The first and second antenna elements-are fed by, for example, a coplanar waveguide feed line, slot feed or the like. Thus, an omnidirectional antenna is realized having simple construction, reducing a size and production cost.
