This paper presents a new compact broadband coplanar slot antenna for multiple wireless communication applications which include WIMAX, RFID, WLAN and ISM bands. The antenna structure is based on the CPW-fed combined with a slot technique and a modified geometry antenna in order to enlarge the bandwidth. The antenna parameters have been investigated and optimized by using Momentum software integrated into ADS” Advanced Design System” from Agilent Technologies with a comparison of the results using another simulator CST Microwave Studio. The measured input impedance bandwidth, ranging from 2.15GHz to 4.4GHz, is obtained with a return loss less than - 10dB, corresponding to 66.7% at 3.27GHz as a center frequency. The design considerations for achieving broadband antenna and both experimental, simulated results are presented.
