Abstract (en)
The underlying invention generally relates to the field of microwave antennas applied to Smart Handheld Devices (SHDs) with high-speed mobile access, and, more particularly, to a new solution for a monopole antenna (106) characterized by an omni-directional radiation pattern (900), in which said monopole antenna (106) is formed by a conductive patch printed on the same substrate (104a) where the RF front-end chip is placed, thereby having the capability of a simple planar feeding, improving cost manufacturing. Said monopole antenna (106) can advantageously be applied to an antenna system comprising at least one dielectric substrate (104a) with a metallized grounded back plane (104b), one metallic reflector box (102) with at least one metallic reflector plane (103), and at least one microstrip line (105) printed on said dielectric substrate (104a) serving as an electrical feeding from an impedance matching network to the radiation element (106). <IMAGE>
