A CPW-fed slot antenna with rhombus patch radiator is proposed for 1.2276/1.5754/1.8/2.4/2.45/5.0/5.2/5.8 GHz wireless communication applications. The pentagon and rectangular slots are etched on the metallic layer of a single sided printed circuit board and rhombus patch radiator with a tuning stub in the feeding structure is embedded to form the proposed slot antenna. The dimensions of pentagon slot and tuning stub are changed to design and fabricate the antenna which can be operated at 1.2276/1.5754/1.8/2.4/2.45/5.0/5.2/5.8 GHz successfully. IE3D software is used to design this CPW-fed slot antenna and choose the better parameters to manufacture the proposed antenna. The influences of slot and stub dimension parameters of the proposed antenna on resonant frequency, input reflection coefficient expressed in decibel and impedance bandwidth are described. The proposed antenna with the volume of 100mm×80mm×0.6mm has been fabricated. The measured result shows that the proposed antenna can be successfully operated at 1.2-2.8 GHz and 3.35-7.56 GHz bands. These bands are suitable for IoT-based applications.
