Abstract
A new class of microstrip travelling wave antenna of large bandwidth is described. The log-periodic array is composed of flat short-circuited half dipoles acting at quarter-wave resonance and fed in series by means of a high characteristic impedance microstrip line. A model has been constructed and tested. A large squinted main beam is obtained between 0.75 and 4.5 GHz. The constant experimental radioelectric properties are in good agreement with the theoretical predictions.
