A multi-element coplanar waveguide continuous transverse stub (CPW-CTS) antenna for wireless communications

A three element CPW-CTS array antenna is described. The advantages of this new design include low cost, low profile, light weight, and a very simple planar microstrip feed configuration. The three element antenna exhibits a well-formed broadside main beam with up to 31% decrease in HPBW (compared to a single element CPW-CTS) at the 10 GHz frequency band and good 50-ohm impedance match (-10 dB) from 9.9 to 10.3 GHz. For future work, experimental verification will be performed and measured data will be compared with simulated results. The multi element CPW-CTS array represents the first step towards a large multi-panel planar array.
