A 1 × 4 cylindrical dielectric resonator antenna array with a steerable beam pattern is designed, fabricated and presented in this paper. The cylindrical dielectric resonator antennas, with a dielectric constant of 34, are excited using aperture coupling and are operated at the fundamental HE11𝛿 mode. Four PIN diode phase shifters, printed on the same Rogers 4003 substrate, with a dielectric constant of 3.55, are used to steer the main beam on three directions, at 5.2 GHz. The maximum steering angle obtained was ± 36 degree. A practical model has been implemented. The practical results are similar to the simulation results..
