Abstract
In this work, a frequency scanning array of antipodal linearly tapered slot antennas is presented. The system is capable of performing beam steering from –11 to 10 degrees while sweeping the frequency from 8.25 GHz to 11.5 GHz. The beam scanning is achieved by means of a specially designed feeding network that divides the power and introduces the proper phase shift for each antenna port in the frequency range of interest. Experimental results showing the full array behaviour are also presented.
