“…The structure of the patch is deformed in [16] with spline-based geometry, for which significant improvement in bandwidth is achieved, but the size remains large. A coupler based on half mode substrate integrated waveguide (SIW) is explored in [17], which achieves a wide bandwidth with a rapidly varying phase difference between output ports. A wideband coupler is reported in [18], which is based on rigid gap waveguide making it bulkier and expensive.…”

In this paper, a novel branch line coupler with improved bandwidth and reduced size is presented. The size reduction is achieved by means of capacitive loading. The capacitive loaded transmission line implemented in the proposed design eliminates the need of open stubs. The mechanism of size reduction and bandwidth enhancement of the coupler is discussed analytically with the help of its equivalent circuit. A prototype is fabricated and tested to validate the concept. The measured fractional bandwidth is 40%, ranging from 2.8 GHz to 4.2 GHz which is suitable for 5G systems. Moreover, the obtained phase imbalance between the output ports is less than ±5 • for the entire operating range.

The use of substrate integrated waveguides (SIW) for microwave and millimeter wave integrated components has increased dramatically over the last decade. They mimic the performance of conventional metallic waveguides and they are fabricated using printed circuit boards using the top and bottom metallization with two rows of vias forming the side walls. This creates a low profile, compact, and light weight alternative to conventional metallic waveguides, and they allow a direct interconnection with printed circuit boards and active components. This article reviews the fundamental theory, documents the research that has been performed over the past decade, and summarizes progress up to the recent state-of-the-art including novel SIW structures for passive circuits and antennas as well as new applications for reconfigurable and printed circuits using SIW technology.

In this paper a -3 dB, 90-degree phase shift RF quadrature patch hybrid coupler is designed to operate at 2.4GHz. Hybrid coupler is a fourport device, that's accustomed split a signaling with a resultant 90 degrees' section shift between output signals whereas maintaining high isolation between the output ports. The RF quadrature patch hybrid coupler is used in various radio frequency applications including mixers, power combiners, dividers, modulators and amplifiers. The desired hybrid coupler is designed using FR-4 substrate with 1.6mm height in High Frequency Structure Simulation (HFSS) and the same is fabricated and tested. The designed Hybrid coupler is examined in terms of parameters like insertion Loss, coupling factor and return Loss. The simulation and measurement results are compared. Major advantages of the RF quadrature patch hybrid couplers are that they are compatible with integrated circuit technology.
