Design and fabrication of 2-way Wilkinson power divider for dual operating frequencies

Abstract

This paper presents design and fabrication of 2way Wilkinson power divider (WPD) for dual operating frequency. This WPD use dual operating frequencies on 2.4GHz and 4.928GHz. In this WPD, two branches of impedance transformer and the output ports are shunted with parallel connection of a resistor (R), an inductor (L) and a capacitor (C).Simulation and measurement results of this WPD design are shown by the graphs of insertion loss (S21 and S3t>, return loss both of input and output (Sl1, S22 and S33) and also isolation between the output ports (S32). Based on the simulation and measurement results, this WPD have a better insertion loss and isolation, and also produce a better return loss of input and output ports for operating on the both frequencies of2.4GHz and 4.928GHz.

A Compact and Lightweight Microstrip Antenna Array with Wilkinson Power Divider for X-band Application at 9.5 GHz

“…For isolation factor analysis, it is expected that a higher isolation factor is obtained in order to achieve a lower mutual coupling [8]- [9]. The simulated S 23 and S 32 (Fig.…”

“…For insertion loss analysis, both parameters of S 21 and S 31 ideally should be equal to -3 dB [8]- [9]. From Fig.…”

“…It follows that an array antenna needs to operate along with a compatible and reliable power divider. There have been numerous studies and on-going researches which explore the performance of microstrip antennas [5]- [7] array antennas together with power dividers [8]- [9] and those specifically used for X-band application [10]- [13]. In [14], a ten-element microstrip patch array antenna is shown to operate in the X-band frequency region at 9.5 GHz with a gain and directivity of 16.5 dB and 17.7 dB, respectively.…”
