Abstract :
The planar phased array of log-periodic dipole array (LPDA) elements is analyzed to investigate the broadband characteristics of the array antenna. The method of moments (MoM) is used for the numerical analysis. The scan pattern, the actual gain, the sidelobe level, and the scan angle deviation are calculated to evaluate the scan performance.
