This paper studies the open end effect in parallel coupled transmission lines. The parallel coupled transmission line that has an open ended through port and an isolation port connected with 50 ohm transmission line is simulated using an electromagnetic simulation tool. The equivalent circuit having a negative phase is extracted using the Designer V4(Ansoft co.) de-embedding technique. The open end...
This paper presents a dual-band 2 section Wilkinson power divider. The proposed method is used that transmission lines of the divider are transformed to pi-type equivalent circuits, which can be same impedance and electrical length. To validate the proposed method, we design a dual-band divider which is used for 0.9 GHz cellular and 1.8 GHz 3rd generation system. The specified dual-band divider which...
