Design of Compact CPW-Fed Microstrip Slotted Multiband Antenna for Wireless Applications
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 3
Abstract
In this paper, a slotted micro-strip multiband antenna fed by a coplanar waveguide (CPW) for Wireless applications is proposed. The antenna consists of a rectangular metal radiating patch of dimensions 30 x 20 x 1.6 mm3 comprises four Lshaped slots and one rectangular slot etched in it. By introducing the slots, five resonant frequencies including 2.4/5.2/5.8 GHz for WLAN, and 2.5/3.5 GHz for WiMAX, are excited. The simulated results show that the proposed antenna has five fine impedance bandwidths (S11< -10 dB) of 0.11 GHz (2.54–2.65 GHz), 0.10 GHz (3.76–3.86 GHz), 0.11 GHz (5.11-5.22 GHz) for WiMAX band and WLAN band in lower frequency bands. For the upper bands impedance bandwidth reach 0.53 GHz (8.84-9.37 GHz) and 0.57 GHz (12.25–12.82 GHz) which are capable to cover the satellite and fixed microwave communication bands. Furthermore, the obtained radiation patterns are Quasi Omni-directional patterns in E-plane, and Omni-directional pattern in H-plane.
