Abstract
This thesis presents a compact dual-band microstrip patch array
antenna for both fourth generations (4G) Long Term Evolution (LTE) at
3.5GHz and also Wireless Local Area Network (WLAN) at 5 GHz
respectively. The two applications use Multiple-Input Multiple-Output
(MIMO) configuration to increase the capacity of the transferred signal as
compared to other configurations.
Design, simulation, and implementation processes are carried out with
the aid of the Advanced Design System (ADS) Electromagnetic (EM)
simulator tool that uses the full-wave Method of Moment (MoM)
numerical technique.
Single element and linear sub-arrays with 1x2 and 1x4 dimensions are
designed, simulated for both copper and Multi-Walled Carbon Nanotubes
(MWCNT) materials, and implemented for MWCNT only to provide the
advantage of using such materials over the copper one.
The copper antenna is fabricated from available commercial
component in Military Technology College in Cairo. A good agreement
result between simulation and fabrication measurements is obtained.
To confirm that the ADS works efficiently on MWCNT materials, we
compare it with the Computer Simulation Technology (CST) EM
simulator tool to simulate the square antenna for the same parameters.
Close-agreement results are given for both packages.
Extending this contribution for copper, planar array antennas with 4x4
and 8x8 dimensions are designed and simulated.
Beam steering of the pattern main-loop to different angles in both
azimuth and elevation directions are done. The steering is done with and
without adaption of the amplitudes.
