A microstrip-fed modified printed bow-tie antenna for simultaneous operation in the C and X-bands

This paper presents a modified printed bow-tie antenna designed to simultaneously operate in the C and X-bands from 5.5 to 12.5 GHz. This new antenna design provides an end fire radiation pattern suitable for integration in single and dual polarized phased array systems. The antenna exhibits small size and wide bandwidth approaching 91%. The radiation characteristics are presented for a single element and for a linear array configuration.
