Abstract:
In this paper, a novel broadband monopole antenna with an extended rectangular shaped slot based on coplanar waveguide (CPW)-fed is designed and presented. The antenna composed of a planar rectangular patch element embedded with a slots, capable of generating two separate resonant modes with good impedance matching. The parametric study is performed to understand the characteristics of the proposed antenna. To verify the simulated design concept, a prototype antenna is designed and fabricated on the FR4 substrate, and characterized experimentally. The overall size of the antenna is 35.24 mm×26.4 mm×1.6 mm including the finite ground CPW feeding mechanism and total volume of the antenna is 1.49 cm3. The antenna operates in broad frequency bands from 3.424 GHz to 6.274 GHz covering wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) bands. The maximum gain of the proposed antenna is 5.51 dBi at 4.78 GHz frequency band. The proposed antenna‟s radiation characteristics are also observed.
