MULTI BAND MICRO STRIP PATCH ANTENNA FOR WIRELESS APPLICATIONS

This research paper aims to design a new shape of the microstrip patch antenna. Combining a half circular and zigzag shape of a triangular patch antenna, we selected two different shapes of microstrip patch to obtained modern shape no one mentioned it before and it’s seems like a tulip rose, so this design achieved to works for multiband. The dimensions of the proposed antenna are (38×30×1.6) mm3 applied on the dielectric substrate FR-4, which has a relative dielectric constant of (εr=4.3) and loss tangent (tanδ=0.002). Both patch and ground are copper material with a thickness (t=0.035 mm). So four-band are achieved (5.1612-5.3874) GHz, (8.8729-10.067) GHz, (10.476-11.091) GHz, and (13.819-30) GHz. The return loss (S11) are (-20.784) dB, (-30.532) dB, (-19.246) dB and (-29.789) dB respectively. The antenna is printed by using FR-4 substrate and simulated by CST-Microwave studio software. This antenna works for various wireless applications such as Wi-FI, C band, X band, Ku band, Ka-band, cellular phones, and satellite communications.
