This paper presents the design and performance analysis of a high-gaindipole antenna using a partially reflective Meta surface (PRMS) layer and a parasitic director element operating at 3.2 GHz in the S-band. Conventional dipole antennas exhibit low gain and bidirectional radiation, which limits their efficiency in modern communication systems. The existing work on high-gain broadband dipole antennas using PRMS layers demonstrates gain improvement through Fabry–Perot cavity formation. However, further enhancement in directivity and gain is required for advanced applications. In the proposed design, a planar reflector, PRMS layer implemented using a frequency selective surface (FSS), and a rod-shaped director are integrated with the dipole antenna. The PRMS layer enables partial reflection and forms a resonant cavity, while the director focuses radiation in the forward direction. The antenna is simulated using ANSYS HFSS, and the results show a return loss of approximately –17 dB, VSWR close to unity, and gain around 7–8 dB. The proposed design achieves improved directional radiation and enhanced gain compared to the existing model, making it suitable for S-band wireless and satellite applications.
