Design of Coplanar Dipole Antenna with Inverted-H Slot for 0.9/1.575/2.0/2.4/2.45/5.0 GHz Applications

A coplanar symmetric dipole slot antenna with inverted-H slot is proposed for 0.9/1.575/2.0/2.4/2.45/5.0 GHz wireless communication applications. The inverted-H slot is etched on the metallic layer of a single sided printed circuit board to form the coplanar dipole slot antenna. The dimensions of inverted-H slot are changed to design and fabricate the antenna which can be operated at 0.9/1.575/2.0/2.4/2.45/5.0 GHz successfully. We use IE3D software to design this dipole slot antenna and choose the better parameters to manufacture the proposed antenna. The influences of slot 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 123mm×31mm×1.6mm has been fabricated. The measured result shows that the proposed antenna can be successfully operated at 0.9/1.575/2.0/2.4/2.45/5.0 GHz.
