A new single layer broadband CPW fed-printed monopole antenna for wireless applications

Broadband antennas have been increasingly investigated in recent years for wireless communication systems. Printed antennas fed by coplanar waveguide can provide a wide bandwidth and can be easily integrated with active circuits. In the same perspective, we proposed a new coplanar fed broadband antenna.. The investigated antenna uses printed monopole with two parasitic elements to widen the bandwidth. The design methodology is outlined. This antenna was numerically designed using Ansoft HFSS simulation software package. A parametric study using an electromagnetic simulator was performed. Based on the optimized design, an experimental prototype was fabricated and measured. Simulations and experimental measurements were carried out, and the comparison between them gives a good agreement. Using this approach, a fractional bandwidth of 47% at the center frequency of 2.35 GHz was achieved. This proposed antenna can be used for broadband wireless communications networks.
