Abstract
The present paper deals with a hybrid microstrip coupler designed with 4 communication ports between the antenna. The telecommunication receiver system is utilized to transmit the signals from mobile, X radars with the X waveband (8-12GHz), and static systems. In this work, we used microstrip platform design techniques including Unequal-Split Rat-Race Couplers, Rat-Race Couplers, Wilkinson Power Split, and Line Impedance. These methods are utilized to determine the signal transmission power quantity. The presented design can be run in microwave frequency distances and long-range radars. The value S11 parameter is almost -5.68 dB that is improved compared to the former research. The hybrid coupler has general dimensions of 20 mm × 20 mm, which were decreased to the same size. The simulations were conducted in the CST software.
