Design of a cylindrical parabolic reflector on monopole plasma antenna

A monopole plasma antenna with cylindrical parabolic reflector is proposed. A cylindrical parabolic reflector is placed at the back side of focusing signal to reflect the signal received from transmitter back to the front for increased antenna directivity. The purpose of this design is to enhance the antenna gain and produce strong antenna signal. A monopole plasma antenna positioned at the center of reflector having dimension 310 mm length and 12 mm of diameter is serve as antenna reference. The difference on antenna gain of antenna reference and plasma antenna with reflector was studied throughout the simulations and the performance in terms of return loss and radiation pattern is observed in simulation and measurement results. This antenna is operating at 4.3GHz frequency which is suitable for wireless communication applications.
