In this paper, a new compact waveguide-fed flexible antenna is presented for RFID applications. This antenna is operated at the resonant frequency of 2.45 GHz. The proposed antenna is designed with small size on (43 × 30) mm2 epoxy substrate material type (FR4) used in the proposed antenna that has a dielectric thickness of 1.6 mm, the relative permittivity of 4.3 and tangent loss of 0.025 where the FR4 dielectric combines good electrical features, price, and availability. The return loss is less than −10 dB in the frequency interval (2.1 − 2.98) GHz. The maximum gain of the proposed antenna is 2.47 dB. The proposed antenna has a wide impedance bandwidth, and an omnidirectional radiation pattern with a small size has been achieved. The overall size of the compact antenna are (43 × 30 × 1.67) mm3. The Computer Simulation Technology (CST) microwave studio software is used for simulation
