In this paper, a design and fabrication of miniaturized 5.3 GHz reflection type 360° analog phase shifter with branch line coupler and 360° variable reactance load. In order to miniaturize phase shifter, novel branch line coupler is proposed. The novel branch line coupler is miniaturized using transformation of transmission line to T and π type equivalent circuit. The miniaturized branch line coupler has small size of above 50 % compared with conventional branch line coupler. For wide phase shift range, 360° variable reactance load structure is adopted. Especially, the structure was improved for linear phase shift by adding transmission line which acts as an impedance transformer. The improved structure was miniaturized using the equivalent lumped-element of transmission line. The fabricated phase shifter with 15×15 mm 2 shows wide phase shift of above 480°, the insertion loss of -4～-6 dB and the reflection loss of below -20 dB at 5.3 GHz under 0～10 V control voltage range.
