Abstract
Abstract An antenna arrangement includes a microstrip antenna which comprises a ground conductor plane and a radiating conductor plane arranged on opposite sides respectively of a dielectric substrate, and a connecting conductor plane connecting together the radiating conductor plane and the groun conductor plane, and a unipole antenna coupled to the radiating conductor plane at one end thereof.
