Compact dual broadband planar slot antenna for wireless LAN application

A new compact dual broadband planar slot antenna that covers two frequency bands of 2.4GHz and 5.2GHz for modern mobile broadband wireless network applications is presented. The antenna structure includes folded self-resonance meander slots as the main radiators, and using the CPW-fed combined with a coupling mechanism at its feeding input to match the large input impedance exhibits at the input of the slot antenna. The use of meander slot together with the coupling CPW-fed feeding network enables us to reduce the antenna size, the manufacturing complexity as well as the operating bandwidth. The antenna is manufactured using the FR4 print circuit board and the results show the wanted characteristics and performance.
