Abstract :
The paper presents a two-dimensional ultrawideband printed antenna array of 64 pentagonal dipoles operating in the 60 GHz range. The shape and dimensions of the dipoles are optimized to obtain as wide as possible bandwidth. The bandwidth is greater than 30%, gain is between 22 dB and 23.5 dB, sidelobe suppression is better than 10 dB, and cross-polarization suppression greater than 35 dB.
