A novel structure of filtering antenna working at a center frequency of 10 GHz with a fractional bandwidth of 10% is presented in this letter. It consists a third-order Chebyshev filter with resonators coupled by shifted layers and an array of two aperture antenna elements in the end. This new structure without any iris is very suitable for machining layer by layer. Therefore, it would be a solution in some special conditions in which traditional ways of manufacture could not be realized. In the end, the antenna array is fricated by computer numeral control (CNC) milling technology. Conclusion and analysis to the measurement are presented, as well as the methods for improvement.
