AB  - In this study, design and construction of a folded dipole log-periodic stack array antenna operating at UHF/L band (900-2000 MHz) for GSM base stations applications are presented. Two major parameters, namely the gain and radiation patterns were measured and used to evaluate the performance characteristics of the proposed antenna. The results obtained show that the antenna’s measured gain varies between 8.8 and 13.2 dBi over the impedance bandwidth of 900-2000 MHz. Also, the measured radiation patterns of the antenna show omnidirectional patterns with the beamwidth >90° for all resonant frequencies within the band.
