In this paper, a miniaturized rat race coupler with stub loaded transmission lines is proposed to operate at WLAN 1 frequency i.e., 2.4 GHz. A comparative analysis has been made by replacing the conventional quarter wavelength transmission lines by stub loaded transmission lines. The proposed model has been designed on RT Duroid /5880 substrate and simulated using AWR Design Environment. Subsequent harmonics in the conventional rat race coupler are suppressed by reducing the electrical length less than 450. Simulation results of the designed coupler agrees well with the theoretical design. © 2016 IEEE.

Miniaturization of a novel rat race coupler: A comparative analysis

2016 Thirteenth International Conference on Wireless and Optical Communications Networks (WOCN)

A miniaturized rat-race coupler operating at a frequency of 5.8 GHz encompassing harmonic suppressions is proposed. In order to reduce the overall size and to improve the performance of the coupler, the quarter wavelength transmission lines are replaced by their equivalent stub loaded lines. The electrical length corresponding to the minimum harmonics that miniaturize the rat-race coupler are compared. A comparative analysis of area of the coupler with different electrical lengths is carried out using AWR Design Environment. © 2017 IEEE.
