Abstract

The growing demand for high data rates, wide spectral coverage, and precise system performance, particularly in 5G and IoT, has accelerated the need for broadband antennas with stable gain and consistent broadside radiation patterns. To meet these requirements, we propose the fabry perot cavity resonator (FPR) antenna, where electromagnetic field oscillations resulting from multiple reflections between two parallel reflective surfaces enable ultra wideband operation through constructive interference. The design employs a dipole antenna as the primary radiating element, enclosed by a reflecting surface in ' c' shape that combines the features of an FPR and a yagi-uda antenna. The proposed antenna operates over 1.5 GHz to 3.5 GHz frequency range, exhibiting a stable broadside radiation pattern and a consistent gain of approximately 3 dB, with a reflection coefficient (S11) performance better than <-10 dB across the band.
