Dual-band patch antenna array for WLAN applications

A compact antenna array consists of 2 elements dual-band patch with asymmetric coplanar waveguide (ACPW) feeding structure and a dual-band Wilkinson power divider feeding network is proposed in this article. The radiated patch was chiseled two cross-slots, there are shorted-lines to be set at the middle-and cross-points of slots, which is designed to be operated at dual-ISM band (2.4GHz and 5.8 GHz bands). A prototype of the proposed antenna with 98 mm in length, 6 mm in height and 142 mm in width is fabricated and experimentally investigated.
