Abstract :
A tapered slot antenna (TSA) operates at Ka band with high gain and broadband is designed in this paper. The TSA is printed on two side of the substrate. A SIW transformer between the microstrip feedline and the TSA is applied to minimize the feedline losses for forming antenna arrays. The simulated bandwidth of the reflection coefficient less than -10dB is 26GHz from 25GHz to 51GHz. The front-back ratio is 15dB and the half power beam width is 60°. This prototype is fabricated and measured to verify this design. It is easy for this antenna element to be expended to array and applied in millimeter wave power transmission and imaging.
