A Hexa-band Gysel Power Divider for Microwave Applications

This paper presents a hexa-band Gysel power divider (GPD) for microwave applications. By replacing each λ/4 transmission line (TL) of the conventional GPD by the hexa-band λ/4 TL the proposed GPD has been developed. In order to verify the approach, a hexa-band GPD has been developed on Printed Circuit Board (PCB) for f
₁
= Long Term Evolution (LTE) 0.7GHz, f
₂
= LTE1.7GHz, f
₃
= LTE2.6GHz, f
₄
= 3.9GHz, f
₅
= Public Safety Band 4.9GHz and f
₆
= Wireless Local Area Network (WLAN) 5.8GHz wireless applications and tested. Return loss and isolation better than 13dB has been obtained while preserving the transmission 3.5dB for all the six bands. The first time a hexa-band GPD has been developed.
