Simple UWB Linear Antenna Array Based On Compact Wilkinson And Bagley Power Dividers

Abstract

Simple 2x1 and 3x1 UWB linear microstrip patch antenna arrays are analyzed and designed in this paper. The used feeding networks are based on UWB compact 2-way equal split and unequal split Tapper Transmission Lines (TTL) and Nonuniform Transmission Line (NTL) Wilkinson Power Divider (WPD) and UWB equal split 3-way TTL Bagley Power Divider (BPD). The simulated S11 is less than −10 dB for the designed five antenna arrays through the UWB frequency band. The obtained peak gain is between 4 and 6.5 dBi which can be improved using a high gain antenna. The simulation in this work is carried out uses High-Frequency Structure Simulator (HFSS) software based on the Finite Element Method (FEM).
