Compact wireless transceiver board with directional printed circuit antenna
 A wireless transceiver includes a dielectric substrate having first and second major surfaces on which an RF circuit and a baseband processing circuit are mounted, and a printed circuit antenna formed on the substrate. The printed circuit antenna has at least one director formed by strip conductors disposed on the substrate, a reflector formed by the edge of a ground area disposed on the substrate, and a dipole formed by strip conductors on the substrate. The dipole is positioned between the reflector and the director. An antenna with this low profile and compact antenna structure has high directivity.
