| Summary: | In wireless communication systems, antennas with reconfigurable polarization are
required to minimize multipath fading losses and enhance signal transmission
performance by minimizing polarization mismatches and interference with other
systems. The polarization of electromagnetic waves emitted by the antenna may
experience depolarization during propagation, resulting in Polarization Loss
Factor (PLF) and reducing the received power intensity. Reconfigurable
polarization microstrip antennas are proposed to address this issue. This research
involves the design, simulation, and realization of microstrip antennas with
reconfigurable polarization. These antennas operate at frequencies of 915 MHz and
1,575 GHz. Furthermore, the antenna is applied as a sensor to observe the impact
of polarization on the measurement results of radiated emissions (RE) from the
Equipment Under Test (EUT). Simulation and realization results show that the
designed antennas have the capability to switch between circular and linear
polarizations. In the RE measurements, microstrip antennas with circular
polarization design produce lower electric field strength levels than antennas with
linear polarization design in vertical polarization mode and higher levels than
antennas with linear polarization design in horizontal polarization mode. |
