LCP Based Dipole Antenna Fed by Rectangular Waveguide Operating at 60-GHz band

摘要

In recent years, wireless communication with high speed and huge capacity data transmission at 60 GHz band is focused. Kiosk downloading which is a short-range wireless communication is one of 60 GHz applications. Requirements for millimeter-wave devices such as antenna are low loss and broadband operation whose bandwidth is up to 9 GHz. In the short-range wireless communication application, omni-directional radiation or large beam coverage is also required. In this paper, the design and evaluation of a dipole antenna fed by rectangular waveguide, at 60 GHz is reported. The antenna is fabricated on liquid crystal polymer (LCP) substrate. The proposed antenna has broadband operation and broad beam radiation so that it is suitable for the short-range wireless communication at 60 GHz band.
