Abstract :
The large class of travelling wave antennas includes many examples which are superficially quite different, such as the helical antenna, the dielectric antenna, the corrugated surface, and the long Yagi antenna. The essential similarity of these antennas is discussed, and it is shown that the pattern bandwidth is inherently large, and separable from the impedance bandwidth. Broadband methods of excitation are discussed which allow for operation over frequency ratios as high as 2 to 1. Experimental results are presented on the broadband operation of a 10 wavelength Yagi antenna.
