The Design of Log-Periodic Dipole Array (LPDA) Antenna for 5G Application Using SIW Technology

A novel log-periodic dipole antenna array based on substrate-integrated waveguide technology is presented in this paper. The antenna is powered by SIW, streamlining the structure and minimizing losses. The performance of the antenna array was designed and simulated within the millimiter band from 22 to 40 GHZ. The modelled antenna constructed on Rogers RT5880 substrate with height of 0.508 mm and a relative permittivity of 2.2. Results obtained from Simulations using the CST simulator indicate that the antenna array operates at 26.86 GHZ whith a return loss of approximately -45.62 dB and an average gain of about 7.62 dBi.
