Abstract :
Arc antenna arrays for high frequency band are examined. The optimal length of log-periodic array elements is discussed. The expression for array dimensions are derived which ensure constant beam width within frequency range. It is shown by means of computational modeling that for keeping of constant beam width the length of element should be extended.
