“…Adding an open or short stub network to the WPD arms is a very common technique in broadening the BW without adding an extra length for the PD. For instance, a single stub network was used in [26][27][28][29], double stubs in [30,31], and triple stubs in [32]. Furthermore, different shapes of stubs can be used other than the conventional rectangular stub like radial stub [33] and triangle stub [34].…”

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.

“…Using open-ended stubs [17][18][19][20][21][22] or a compact resonant cell [23] in the main structure of the WPD are other techniques for harmonic suppression and size reduction. However, both wide-band and harmonic suppression merits are not realized simultaneously in the cited works.…”

In this paper a Wilkinson power divider (WPD) is presented with ultrawide-band operation and harmonic suppression. This WPD is designed using coupling lines and meandered open stubs at main branches. The center frequency of the presented WPD is 4.25 GHz, which is fabricated and measured on RT/Duroid substrate with dielectric constant of 2.2. The proposed WPD provides good filtering band with high attenuation level. The 15 dB return loss operational bandwidth (BW) of the WPD is obtained between 3.2 GHz and 5.3 GHz, which shows 50% operational bandwidth.
