Design of a Modified Wilkinson Power Divider for Ultra-Wideband Antipodal Vivaldi Antenna Arrays
Journal Title: International Journal of Innovations in Science and Technology - Year 2025, Vol 7, Issue 2
Abstract
This paper presents the design of a two-wayModifiedWilkinson power divider(MWPD) feeding networkfor atwo-element Antipodal Vivaldi Antenna (AVA) array, operating in the 3–10 GHz ultra-wideband (UWB) frequency range. The proposedfeeding network is optimized by incorporating bent corners, which help reduce unintended radiation and improve signal distribution. Additionally, the antenna design is enhanced using a compact structureto improve radiation performance and impedance matching.The design, simulation, and optimization of both the feeding network and antenna array are conducted using CST Microwave Studio.Experimental validation confirms that the proposed array meets UWB specifications, making it a suitable candidate for wideband communication and imaging applications.
