A study of printed cross‐dipole antenna with slow‐wave parasitic elements used to achieve high efficiency and directivity is presented. The proposed antenna is designed to operate at WLAN channels (5.15–5.85 GHz), and can produce dual‐orthogonal polarisation through a crossed structure. The printed slow‐wave elements play a role that concentrates on travelling wave and delays propagation of electromagnetic wave. Measurement results of this antenna show that it has high gain, low side‐lobe level and wide bandwidth. This proposed design has advantages in terms of manufacturing the antenna easily and optimising the radiation characteristics.
