%A Tang, Toan The %A Nguyen, Tran Minh %A Truong Vu Bang, Giang %D 2017 %T A Feeding Network with Chebyshev Distribution for Designing Low Side-lobe Level Antenna Arrays %K %X This paper proposes a feeding networking to gain low sidelobe levels for microstrip linear antenna arrays. The procedure to design  a feeding network using Chebyshev weighting method will be proposed and presented. As a demonstration, a feeding network for  8 × 1 elements linear array with Chebyshev distribution weights (preset sidelobe level of -25 dB) has been designed. An unequal  T-junction power divider has been applied in designing the feeding network to guarantee the output powers the same as Chebyshev  weights. The obtained results of the amplitudes at each output port have been validated with theory data. The phases of output  signals are almost equal at all ports. The proposed feeding network, therefore, can be a good candidate for constructing a low  sidelobe level linear array antenna. %U //jcsce.vnu.edu.vn/index.php/jcsce/article/view/157 %J VNU Journal of Science: Computer Science and Communication Engineering %0 Journal Article %R 10.25073/2588-1086/vnucsce.157 %V 33 %N 1 %@ 2588-1086 %8 2017-10-02
