Abstract
An antenna includes a cylindrically shaped dielectric resonator placed on a longitudinally extended axis of an elongated dielectric strip disposed on a planar conductor and another planar conductor having an opening covers the dielectric strip with the opening on the dielectric resonator. There may be another dielectric strip placed perpendicularly to the first dielectric strip such that the dielectric resonator is where the lines longitudinally extended from the axes of both dielectric strips will cross.
