Abstract

This paper presents novel printed array antennas fed by CPW (coplanar waveguide) configuration with a corporate feed line on single layer that will be used to form an agile focused beam for the 60-GHz radio. This type of coupling eliminates the competition for surface space between the antenna elements and the feed network. Besides, the ground plane shields the antenna half-space from spurious radiation emitted by feed lines and active devices. The array antennas is designed on a high dielectric constant substrate (epsivr = 9.9), which demonstrates the feasibility of integration of such antenna structure into monolithic circuits. The array antenna is the key component in a smart antenna system used in a prototype of broadband wireless LAN system operating at up to multi-Gb/s.
