摘要：In this work, a new antenna will be presented in the form of F-inverted working at 28Ghz frequency is proposed for 5G wireless com- munications. This antenna has been designed based on an FR-4. with shaped slots on the patch and interdigital slots in the ground for band- width enhancement. The PIFA antenna has an operating frequency of 28 GHz with S11,-39.0885 dB, while the peak gain is 7.85dBi. Therefore, it is suitable for applications of 5G wireless communications with good matching and return loss characteristics. The proposed design model and performance evaluation of the PIFA antenna has been executed by CST Microwave Studio and HFSS.
