A 30 GHz Bow-tie Slot Antenna Fed by a Microstrip to CPW Transition

摘要

A modified bow-tie slot antenna fed by a microstrip to coplanar waveguide (CPW) transition, is designed for wide band operation. The design is suitable to be included in arrays for applications in radar and wireless communications, providing a possibility to be utilized in experiments based on studies of the cosmic microwave background (CMB). Simulation results in this study show around 43% bandwidth with VSWR < 2 in the frequency range from 25 to 40 GHz.
