In this paper a multi frequency U-slot patch antenna for wireless applications is presented. The proposed antenna operates at four frequencies of 1.4GHz, 5.3GHz, 6GHz and 6.9GHz with return loss of -19dB, -22.50dB, -21.05dB, -19.37dB respectively. The antenna is designed with Rogers R04232 substrate with dielectric constant of 3.2 and dielectric loss 0.043 with dimensions of 47 × 54 × 1.5 mm 3 . Coaxial feed technique is used as a feed to the antenna which is having characteristic impedance 50 ohm. The simulation studies were carried out using Ansys HFSS 15.0 Software.
