Meander line allowed for reducing the size of the component. The coupler demonstrates a coupling level of 2.29 dB, a reflection level of 25.39 dB and an isolation level as 42.41 dB. The meandered coupler have the compact sizes of 23×34.6 mm2, and a characteristic impedance Z0 of 50.60 . in order to validate our model, the compact coupler is designed and fabricated using microstrip technology on FR4 substrat. Good agreement is achieved between the simulated and measured resultsenA Microstript coupler with improving the characteristic transmissionArticle
