Design of a Broadband CPW-Fed Monopole Antenna for WLAN Operations

In this paper, a novel broadband design of a Co-Planar Waveguide (CPW)-fed planar monopole antenna with double plus shape slots is proposed. The design considerations for achieving broadband operation of the proposed plus sign slot antenna are discussed, and theoretical results are presented. The antenna operates in single wide frequency bands from 4.789 GHz to 6.318 GHz covering WLAN bands with a total bandwidth of 1.529 GHz. The overall size of the antenna is 44.53 mm ? 35.87 mm ? 1.6 mm including the finite ground CPW feeding mechanism and total volume of the antenna is 2.56 cm3. The parametric study is performed to understand the characteristics of the proposed antenna.
