Configuration requirements for log-periodic array antennas
Paper in proceedings, 2011

Log-periodic array antennas can provide a constant radiation performance and good reflection coefficient performance over a wide frequency band, which can be considered as an important characteristics of this type antennas. In this paper, the configuration requirement for general log-periodic array antennas is presented in order to have constant radiation function and periodicity of the reflection coefficient. Therefore, a guide rule for designing a wideband log-periodic array is obtained and a more efficient numerical simulation method can be applied for purely log-periodic array antennas.
