Modern mobile communication technology and mobile phone business are developing at a rapid pace, the mobile phone is constantly being updated. PIFA antennas are widely used in mobile communication terminal devices such as mobile phones for their small size, lightweight, low profile and other advantages. The research on using PIFA antenna to achieve multi-band, miniaturization, broadband and other functional characteristics has made certain achievements. In this paper, the structure of the PIFA antenna itself is optimized with the objectives of high accuracy, high integration and economy, the real geometry of the PIFA antenna is modelled through simulation, and the frequency range of the antenna tuning applicable to the AWS band is limited, the spatial electric field distribution, the far-field radiation gain characteristics and the S-parameter characteristics of the antenna are explored under the influence of different parameters, and finally, its wireless communication capability is analysed and summarised and It is then compared with the operational specifications of modern portable communication devices.
