A novel compact wideband antenna for wireless local area network
(WLAN) applications in the 2.4 GHz band are presented. The proposed
low profile antenna of dimensions 15 x 14.5 x 1.6 mm offers 18.6%
bandwidth and an average gain of~5 dBi. The antenna can be excited
directly using a 50 coaxial probe
In this paper, a multiband antenna using a novel
fractal design is presented. The antenna structure is formed
by inscribing a hexagonal slot within a circle. This base
structure is then scaled and arranged within the hexagon
along its sides without touching the outer structure. The
proposed CPW fed, low profile antenna offers good
performance in the 1.65 – 2.59 GHz, 4.16 – 4.52 GHz and
5.54 – 6.42 GHz bands and is suitable for GSM 1800/1900,
Bluetooth, IMT advanced systems and upper WLAN
applications. The antenna has been fabricated on a substrate
of height 1.6 mm and εr = 4.4 and simulation and
experimental results are found to be in good agreement
