Summary:
A uniformly spaced comb taper slot antenna array is proposed for directional ultra-wideband (UWB) applications. The UWB array consists of four identical comb taper slot antennas, a mutistage with four-way microstrip UWB power divider, and four identical coaxial cable lines. A maximum gain of 15.5dBi within the band is obtained when the element separation is properly selected. The uniform spacing between adjacent array elements is 2.5 cm in the H-plane. The performance of the antenna array and the other important parameters are investigated. It is proved experimentally that the proposed antenna array is suitable for the directional UWB antenna array.
