“…Ref. [21] introduced a multilayer wideband PD, where a patch on the top layer (input port) was coupled through a slot on the middle layer to two half-patches (output ports) on the bottom layer. A wide tunable division ratio PD was proposed in [22] with two varactors for controllability.…”

This paper presents a single stage 2-way Wilkinson Power Divider (WPD) suitable for Internet of Things (IoT) low frequency applications in the band from 200 MHz to 1 GHz. It is realized using a meandered line, and an open shunt stub matching network is added to get a compact structure. Moreover, a Vertical Periodic Defected Ground Structure (VPDGS) is added below each arm in order to improve the performance at the center frequency without adding extra length to the divider. The size of the proposed power divider is 30 × 15.3 mm 2 (0.082λ g × 0.041λ g ). The fabricated power divider achieves a fractional bandwidth of 107%, an input return loss of better than 10 dB, an output return loss of 20 dB, an isolation of better than 10 dB, and maximum exceeded insertion loss of 0.9 dB. The proposed compact power divider is implemented on Rogers RT/Duroid 5880 with thickness 0.254 mm in order to bend on any conformal surface.

“…The couplers are basically power dividers/ combiners with equal or unequal power division and with or without phase shift. Branch line couplers [1,2], power dividers [3][4][5][6][7] and hybrid ring couplers [8,9] are the some of the power dividing/ combining devices. The rat-race coupler is one of basic building blocks used in RF and microwave circuits.…”

In this paper, design and development of compact Rat- Race coupler is presented. The device is designed with commercially available semi rigid coaxial cable. The semi rigid coaxial is modified for desired impedance to suit the requirement of Rat- race hybrid coupler. The physical structure of the coupler is in rectangular form instead of the conventional ring form. With this structure, all the ports are available in line on the same side. This eases the integration of the device with other modules or devices in the system. The total area occupied the coupler is reduced drastically by meandering the transmission line. The shielded transmission line provides better port isolation and less radiation loss. Design, implementation and measured results are presented.
