In this paper, the radiation characteristics of conventional Vivaldi antenna are improved by proposing a novel design antenna. This proposed is excited through three slots using L-probe microstrip feeder. The can provide higher gain and wider bandwidth compared to that same size. CST MWS software used simulate measured simulated S-parameters were so feasibility was validated. show impedance fro...

Due to the tremendous development in field of wireless communication and its use several fields, whether military or commercial was proposed. A novel tapered slot Vivaldi antenna is designed simulated at double band frequency (Ku-band) using computer simulation technology (CST) software 2020. The dimensions are 2.3 × 1 0.4 mm<sup>3</sup> with a microstrip feed 0.5 mm. proposed impro...

A wideband feed network for a Vivaldi antenna array is presented. limitation of current arrays the bandwidth either or element. The proposed consists four antennas fed with an improved to extend useable array. coplanar waveguide-to-slotline-to-microstrip line transitions. has single waveguide input and microstrip output ports. achieved uniform amplitude phase balance impedance 160% from 1 GHz 9...
