Summary :

This study aims to propose a novel traveling-wave series-fed microstrip array antenna and its design. The proposed antenna has two features: additional slits placed on the output side of the antenna element are introduced as a new degree of freedom to control the radiation power from each element. Also, the unequal element spacing is applied to compensate passing phases of each antenna element; meander lines that would increase the insertion loss are not used. A 9-element linear array is designed and tested, and the simulated and measured results agree, thus validating the proposed design.
