Design of a Wideband CPW-fed Monopole Antenna with low volume is of practical interest for the ever growing wireless communication industry. In this regard, the design of a wideband monopole antenna for Customer premises equipment (CPE) for Global System for Mobile Communications (GSM, 900 MHz and 1.5 GHz), Wireless Fidelity(WiFi, 2.4 GHz (2.4-2.484GHz)) , Long-Term Evolution(LTE, 0.9GHz - 2.6 GHz) applications by using Co-Planar Waveguide fed is proposed. Bandwidth enhancement is obtained by modifying the patch of antenna by cutting the corners like steps. The parametric study is performed to understand the characteristics of the proposed antenna. The antenna operates in wide frequency bands from 0.9 GHz to 2.6 GHz covering LTE bands. Also good antenna performances such as radiation patterns and antenna gain over the operating band have been observed and simulated peak gain of the antenna is 4.3 dBi at resonant frequency of 2.6 GHz
