Cellular UHF (Ultra High Frequency) transceiver networks and base transceiver station antenna systems comprise high power phase shifters for changing and adjusting the phases or delays of high-power transmitting signals delivered to antenna elements. In this work, theoretical and practical adjustment method of amplitudes and phases for electronic steering of a phased array antenna pattern are illustrated. In otherwords, a high power phase shifter with an asymmetric power divideris designed. The phases are changed and adjusted progressively, and thus the beam direction changes from -60° to 60°. The UHF phase shifter has been simulated in Advanced Design System (ADS) and CST STUDIO SUITE SPARK3D and measured. The simulations show that the designed and manufactured UHF phase shifter can also handle more than 20 KW and can be redesigned to reach up to more than 100 KW RF (Radio Frequency) power (microstrip/stripline structures) and can control/change phases of transmitting/receiving antennas. The phase shifter can be designed on any low loss substrate. By using this method in planar high power phased array antenna systems, 360° planar beam tilting is also achievable.zzz
