摘要：
In this work, a compact miniaturized microstrip balun is proposed by removing the isolation port of a Rat-Race Coupler (RRC). The proposed balun consists of six quarter-wavelength Transmission Line (IL), and the IL is designed using interdigital capacitor and high impedance TL in parallel configuration. The fractional bandwidth (FBW) of RRC and balun are 37.5% and 33%, respectively, at centre frequency 2.4 GHz for amplitude imbalance of +/- 1 dB and phase imbalance of +/- 8 degrees. The size occupied by the proposed balun is 0.51 lambda(g) x 0.22 lambda(g).
