Abstract
This article presents a coplanar waveguide fed regular hexagonal antenna for ultra wide bandwidth (UWB). Then this antenna is modified to obtain band rejection for the wireless local area network of 5.15–5.825 GHz (IEEE 802.11a) and wireless microwave access of 3.3–3.7 GHz (IEEE 802.16) by incorporating U-shape slots within the hexagonal patch. Notch bands can easily be controlled by few geometry parameters of the U-slots. Return loss, impedance, gain and radiation characteristics of them are studied and discussed here. From the results, it has been observed that the antenna significantly satisfies the Federal Communication Commission’s UWB frequency (3.1–10.6 GHz) range while showing the band rejection performance in the frequency bands of 3.3–3.7 and 5.12–5.9 GHz. The antenna gain varies from 2.6 to 6.4 dB over the whole operating band excluding the notch bands. Surface current distributions and transmission line model are used to analyze the effects of the slots. Measured group delay has very small variation within the operating band except notch bands and hence the proposed antenna may be suitable for UWB applications.
