Résumé: | In terahertz (THz), high gain antennas are required to overcome the atmospheric attenuation and path losses, for this aim the antenna arrays are helpful. In this paper, we designed
and analyzed six terahertz microstrip patch antenna arrays based on diferent substrates,
including homogeneous, periodic photonic crystals and fve new aperiodic photonic crystals substrates in the frequency range of 0.5–0.8 THz, which have applications in the next
generation wireless communication technologies such as imaging, sensing and detection.
The proposed antenna arrays are mounted on a thick polyimide substrate where each of the
modifed photonic crystal substrates is divided into several sets of perforated air cylinder
holes where each set had its particular radius. The simulation has been performed using
CST microwave studio for the proposed antenna arrays which resonated around 0.65 THz
and showed high radiation characteristics compared to the conventional antenna array. The
highest radiation characteristics were achieved by antenna array 6 which is designed based
on aperiodic photonic crystals, which obtained at the resonance frequency of 0.66 THz a
very low return loss of −92.89 dB, larger bandwidth greater than 282 GHz, high gain of
11.77 dBi and radiation efciency of 87.63 %. Whereas, the conventional antenna array
ofered at the resonance frequency of 0.635 THz −29.73 dB, 62.81 GHz, 8.47 dBi and
84.21 %, respectively. Finally, the link budget analysis was discussed by estimating the total
signal loss |
