This paper presents a study and analysis of a high performance microstrip branch-line 3 dB hybrid coupler (BLHC) operating at 2.2 GHz for Long Term Evolution (LTE) application. High and low impedance meander lines are used to miniaturize the conventional Branch Line Hybrid Coupler. A prototype of the proposed coupler is fabricated and tested using a Rohde and Schwarz ZVB 20 vector network analyzer. The measured results agree well with the simulated ones.
