Abstract
In this paper, a new miniaturized microstrip coupler at the center frequency of 3.26 KHz is proposed. 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 results
