In this work, a single-layered CPW-fed slot antenna element for low cost 60 GHz radio applications is designed, modeled and analyzed. The results show a -10 dB impedance bandwidth of over 7 GHz with a radiation efficiency of over 95 % making it suitable for short-range WPAN/WLAN applications. It is shown that two of the slot antennas can be configured orthogonally to achieve polarization diversity when fed separately. An isolation of at least 18 dB is obtained with an element spacing of lambda/2. This can be advantageous for applications where the orientation of the terminal is not known.
