Vivaldi Antipodal Antenna with triangular slots fed by air-filled RSIW for UWB applications
This paper presents a modified Vivaldi antipodal antenna using air-filled RSIW technology for UWB applications. The structure has a triangular slot edge, extending the bandwidth and increasing the gain. A prototype of the modified antenna was simulated and fabricated. The measured results show reasonable agreement with simulations, validating the design procedure. The proposed antenna offers a low-cost, easy-to-manufacture and compact solution. Additionally, improvements in performance were observed, including a 1 GHz increase in bandwidth and an additional 1.58 dB in gain, compared to the antenna using only the RSIW technology.
