Abstract
In this paper analytical approach to design a broadband microstrip quadrature 3-dB power splitter is proposed and validated. The proposed quadrature splitter in this paper utilizes a double-stage coupled line Wilkinson power divider in conjunction with a modified phase shifter to induce phase delay at one output port. Compared with the conventional T- shaped stub, the proposed configuration of Tweaked T-shaped stubs exhibits better performance without adding any fabrication complexity, which in turn improves the performance of the quadrature power splitter. In testing, the proposed quadrature Wilkinson power divider covers 2–4.5 GHz (fractional bandwidth FBW = 76.9%) working frequency with 10-dB impedance and 15-dB isolation bandwidth. Furthermore, this design has a very good phase and amplitude balance, with a 7° phase and 1 dB amplitude imbalance.
期刊介绍：
Transactions of Electrical Engineering is to foster the growth of scientific research in all branches of electrical engineering and its related grounds and to provide a medium by means of which the fruits of these researches may be brought to the attentionof the world’s scientific communities.
The journal has the focus on the frontier topics in the theoretical, mathematical, numerical, experimental and scientific developments in electrical engineering as well
as applications of established techniques to new domains in various electical engineering disciplines such as:
Bio electric, Bio mechanics, Bio instrument, Microwaves, Wave Propagation, Communication Theory, Channel Estimation, radar & sonar system, Signal Processing, image processing, Artificial Neural Networks, Data Mining and Machine Learning, Fuzzy Logic and Systems, Fuzzy Control, Optimal & Robust ControlNavigation & Estimation Theory, Power Electronics & Drives, Power Generation & Management The editors will welcome papers from all professors and researchers from universities, research centers,
organizations, companies and industries from all over the world in the hope that this will advance the scientific standards of the journal and provide a channel of communication between Iranian Scholars and their colleague in other parts of the world.
