Description:
AbstractA dielectric resonator antenna array is presented which is intended for use as an integrated solar panel antenna on low Earth orbit small satellites, such as CubeSats. This array has a back‐to‐back Yagi‐Uda topology and can steer its beam ensuring a constant flux density at a satellite ground station. This isoflux gain profile is formed by the envelope of the steered beams which are controlled using a single digital phase shifter. The array achieved a beam steering limit of ±66° with a measured maximum gain of 11.4 dBi.
