- Abstract
Three different V-band high gain printed log periodic dipole array (PLPDA) antenna prototypes are proposed. The antenna prototypes are fabricated and tested. A good agreement between the experimental and simulated results is obtained. Results show that those antenna prototypes can operate from 42 to 82 GHz with a fractional impedance bandwidth of 64.5% covering the whole V-band (50-75 GHz). At 60 GHz, the three antenna prototypes have peak gain of 12.64, 23.31 and 26.79 dBi with a gain variation of 3.5 dBi across the whole V-band with stable radiation patterns over the operating band. The proposed PLPDA antenna prototypes achieve good side-lobe suppression, excellent front-to-back ratio in both E- and H-planes and low cross-polarisation levels over the entire frequency range.
