Abstract
In this paper, a wideband tapered slot antenna (TSA) array using substrate integrated waveguide (SIW) technology is proposed for millimeter wave (MMW) applications. Rectangular corrugation structures are used to reduce side lobe level (SLL) and improve antenna gain. A pair of semicircular notches are inserted to TSA element to expand impedance bandwidth by adding surface current path. Then, a 4-element TSA array is designed and fabricated. Simulated and measured results obtain great agreement. The measured operating band is 33-46.8 GHz (relative bandwidth is 34.5 %) for return loss $< -10\mathrm{dB}$. Besides, gain curve has a stable trend at operating band and the maximum gain is 16 dBi at 46 GHz.
