Hexa-Band Branch Line Coupler and Wilkinson Power Divider for LTE 0.7 GHz, LTE 1.7 GHz, LTE 2.6 GHz, 3.9 GHz, Public Safety Band 4.9 GHz, and WLAN 5.8 GHz Frequencies

A hexa-band branch line coupler (BLC) and Wilkinson power divider (WPD) for long term evolution (LTE) 0.7 GHz, LTE 1.7 GHz, LTE 2.6 GHz, 3.9 GHz, public safety band (PSB) 4.9 GHz, and wireless local area network (WLAN) 5.8 GHz frequencies have been proposed, designed, implemented, and analyzed in this brief. To realize the proposed BLC and WPD a hexa-band quarter wave transmission line (TL) with complete derivation for a hexa-band operation has been introduced. A good performance for the BLC/WPD has been achieved over all the six bands with maximum 0.42/0.21 dB amplitude imbalance and 4.81°/0.9° phase deviation. Compared to the most of the existing BLCs/WPDs, the proposed BLC/WPD has simpler design structure and, compact size than the existing hexa and quad-band BLCs/WPDs.
