A printed circuitboard unbalanced dipole antenna is provided for a wireless communications telephone. Digital and/or transceiver circuits are mounted on a wireless telephone circuitboard. In addition, a radiator is formed from a printed conductive line overlying the circuitboard dielectric layer, with an end for connection to a transmission line and an unterminated end. To shorten the overall length of the antenna, the radiator is formed in a series of rectangular or zig-zag meanders with a plurality of first sections with a first orientation and a plurality of second sections with a second orientation, orthogonal, or approximately orthogonal to the first orientation. In some aspects, the radiator first sections overlie the dielectric layer first side and the radiator second sections overlie the dielectric layer second side. Then, the radiator first and second sections are connected with a plurality of vias.
