Abstract

A W-band (75-110 GHz) coplanar-waveguide (CPW)-fed linear tapered slot antenna (LTSA) on rectangular-grooved silicon substrate is presented. Compared to its ungrooved version, the W-band CPW-fed LTSA shows significantly improved endfire radiation patterns in the whole band. Also, the symmetric patterns together with moderately high gain (8-10 dBi), high front-to-back (F/B) ratio (16-28 dB), and low sidelobe level (SLL; -15 to -17 dB for the E-plane and -11 to -18 dB for the H-plane) are achieved. The proposed CPW-fed LTSA is expected to find applications, such as a transceiver antenna in millimeter-wave wireless communication systems, owing to its easy integration with the uniplanar monolithic millimeter-wave integrated circuits.
