Very small form factor with ultra wide band rectangular patch antenna for 5G applications

A rectangular patch antenna resonating at the frequency of 73GHz is presented in this paper. The antenna is designed on RO4730G3 substrate which is newly introduced by Rogers Company for higher frequencies antenna. The experiment shows that antenna cover ultra-wide impedance bandwidth of 35.41GHz ranges from 50.86GHz to 86.27GHz for S11<;-10dB, which cover majority portion of V-Band, E-Band and W-Band. The results also state that the antenna has a good peak gain of the 6.73dB and very small form factor of 0.8mm × 0.9mm.
