“…The proposed PD has a better harmonic suppression of up to 4 f o (7.2 GHz) with center‐feed compared with other PDs as shown in Table 1. Some PDs 18–22 may have slightly smaller size but they do not suppress any harmonics above 2 f o . They are comparatively smaller as they do not include the coaxial to microstrip transition that supports wide impedance bandwidth and harmonic suppression.…”

In this paper, a center‐fed four‐way power divider with wideband harmonic suppression is proposed. A distinguishing feature is the use of sectorially modified Gielis curves (SMGCs) for open stubs, shorted stubs, and stub‐loaded coupled‐line structures, providing more degrees of freedom in the designs to suppress the wideband harmonics. The expressions for the SMGCs, along with the ABCD matrix elements of the stub‐loaded coupled‐line structure having different even and odd mode electrical lengths (θec ≠ θoc) are another distinguishing features presented in this work. The novelty is to use two stages (first and second) with a combination of open, shorted, coupled‐line stubs and tapered transmission lines to achieve good impedance matching and wideband harmonic suppression for center‐fed antenna arrays. The proposed center‐fed four‐way power divider achieves a wideband harmonic suppression of up to 4fo and a relatively wide −10 dB impedance bandwidth of 52%. The proposed power divider is used in a horizontally‐polarized antenna array for wireless L‐band applications.

“…In order to solve this problem, integrating a power divider and a bandpass filter into a single component, namely, filtering power divider (FPD) to realise both functions of specified power division/combination and frequency selectivity simultaneously has become popular. Up to now, many efforts have been made on exploring different FPD designs, such as Wilkinson/Gysel power divider‐based FPDs [1–5] and coupled line prototype‐based FPDs [2, 6–10], substrate integrated waveguide resonant cavity FPDs [11–13], microstrip‐to‐slot transition integrated FPD [14], to name a few.…”
