“…8(c) (f) are calculated as 15 mm, 1.2 mm, 11 nH, and 1 pF, respectively, along with the following formulae regarding the RH segment. (8) where w, t, and h mean the width and thickness of the metal signal trace, and the height of the microstrip-line substrate, in that order. This dual-band hybrid CRLH phase-shift line attains Φ 1 at f 1 and Φ 2 at f 2 as desired, and it is presented by the measured data in Fig.…”

A compact dual-band three-way metamaterial power divider is proposed that has three in-phase outputs. Fully printed composite rightand left-handed (CRLH) unequal and equal power dividers are first implemented for 900-MHz and 2.4-GHz bands with the power-division ratios of 2:1 and 1:1, respectively. An initial 1:1:1 power divider is then achieved by incorporating the input of the two-way equal block into an output of the unequal block, and trimming the interconnection parameters. The condition of an identical phase at the three outputs of the power divider is then met by devising a hybrid CRLH phase-shift line to compensate for the different phase errors at the two frequencies. This scheme is confirmed by predicting the performance of the power divider with circuit analysis and full-wave simulation and measuring the fabricated prototype. They results show agreement; the in-phase outputs as well as the desirable power-division are accomplished and outdo the conventional techniques.

“…Numerous research and design approaches have been carried out to meet challenging requirements, such as multiband, multiport, and shorter power dividers [2], [3]. The conventional dual-band power divider used harmonics [4], lumped elements [5], [6], and a multisection branch line [7].…”

“…The conventional design for this component uses quarter‐wave lines that operate at a single frequency. With ever increasing demand for multiband and multifunction mobile/handheld devices, several multiband design techniques have been proposed [3–5]. It is found that most previous research works have proposed new circuit topologies that are able to operate in several bands simultaneously, while their circuit sizes are kept small.…”

This article first presents a frequency‐selectable branch‐line hybrid coupler.To provide a frequency‐selection function, a dual‐band band‐pass transmission‐line transformer (TLT) with a frequency selective function is used. This is achieved by replacing a dual‐band TLT with a variable capacitively loaded spur‐line filter. The technique is demonstrated with a design at 0.8 and 1.75 GHz. Measured S‐parameter results confirm the validity of the technique. © 2013 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:1661–1663, 2013; View this article online at wileyonlinelibrary.com.
