Abstract :
A novel conductor backed asymmetric coplanar strip (CBACS) fed compact antenna for wireless local area network (WLAN) applications is proposed. The conductor backed design has an additional ground plane at the bottom surface of the substrate compared with conventional coplanar waveguide. This lower ground plane provides an additional mechanical support to the substrate. Moreover, it can act as a heat sink or heat exchanger thereby cools the device by dissipating heat energy. In the area of antenna design, ACS feed has several advantages over coplanar waveguide (CPW) feed. The main advantage is the achievement of compactness in antenna size. The proposed antenna is designed on a flame retardant woven glass reinforced epoxy resin (FR4) substrate having permittivity 4.4. The proposed design has achieved WLAN operation with a compact size of 20×12.5×1.6 mm3.
