Résumé: | In a wireless communication system, a microstrip patch antenna is gaining importance
as a most powerful technology trend and it is applicable for the development
of minimal weight, low profile, low cost and high-performance antenna. However, the designed conventional patch antennas in terahertz encounter several drawbacks including
narrow bandwidth, low gain due to high atmospheric path loss, low efficiency,
and surface wave excitation. To overcome these drawbacks, microstrip patch antenna
arrays based on photonic crystals are advantageous by providing extra performance.
The main objective of this thesis is to develop and analyze array antennas operating
in the terahertz band (0.1-10 THz) based on photonic crystal structures that satisfy
the important requirements of high directivity, gain and radiation efficiency which will
be candidates for use in high-speed communication, spectroscopy molecular, security
imaging, sensing and medical diagnosis. To achieve this goal, commercial software
such as Ansys HFSS and CST Microwave Studio will be used. Further, a variety
of microstrip terahertz patch array antennas based on modified photonic band gap
substrates are designed and analyzed. The radiation characteristics of the proposed
antennas are compared to previously reported papers. Finally, a novel MIMO indoor
communication system using a graphene-based 1 x 2 microstrip patch antenna array
is developed and studied based on different substrates, including homogeneous,
periodic photonic crystals and optimized photonic crystals substrates for terahertz
communications channel capacity enhancement. The outcomes showed a remarkable
enhancement compared with previously reported studies |
