Dipole array for mm-wave mobile applications

This paper provides details on the design, fabrication and measurement of a beam steerable co-linear dipole array for mobile applications at the 28GHz frequency band. The array is designed and fabricated on an industry standard circuit board stack-up, including the non-high performance substrate layers. The 4-element array measures 7.5dBi peak gain and has a 3dB coverage of 90° in elevation and 25° in azimuth.
