The upgrade to the High-Luminosity LHC foreseen in about ten years represents a great challenge for the ATLAS inner tracker and the silicon strip sensors in the forward region. Several strip sensor designs were developed by the ATLAS collaboration and fabricated by Hamamatsu in order to maintain enough performance in terms of charge collection efficiency and its uniformity throughout the active region. Of particular attention, in the case of a stereo-strip sensor, is the area near the sensor edge where shorter strips were ganged to the complete ones.In this work the electrical and charge collection test results on irradiated miniature sensors with forward geometry are presented.Results from charge collection efficiency measurements show that at the maximum expected fluence,the collected charge is roughly halved with respect to the one obtained prior to irradiation.Laser measurements show a good signal uniformity over the sensor.Ganged strips have a similar efficiency as standard strips
