Abstract :
Paper introduces the novel designs of antenna arrays with wideband log-periodic dipole (LPD) radiators for the frequency range 0.7-12 GHz. Main focus is made on characteristics and design features of pyramidal type and linear 45° inclined configurations of antenna arrays from LPD radiators. Numerically obtained and measured results of considered structures as well as their discussion are included.
