Abstract: This paper presents the design of dual-band frequency reconfigurable fork shape planar dipole in the industrial, scientific and medical (ISM) band (2.4 and 5.2 GHz). The proposed antenna can be used for wireless local area network (WLAN) applications. Antenna operates in dual-band as well as single-band mode depending on switching combination. The proposed antenna gives bandwidth of 12.5% and 6.7% for 2.4 GHz and 5.2 GHz, respectively, in dual-band mode while 15.5% for 2.4 GHz in single-band mode. The performance of the antenna is analysed with a ground-free substrate and traditional perfect electric conductor (PEC) ground plane. The same antenna is mounted on a dual-band slotted mushroom-type electromagnetic bandgap (EBG) surface which improves the return loss of the antenna in both bands by 25 dB w. r. t. the PEC-based dipole antenna. The proposed antenna can be used in WLAN applications. The simulations were carried out in SEMCAD and CST MWS.
