“…This characteristic significantly reduces the size of the structure [6]. SPDs are one of the most important power dividers used to provide a simple compact feeding network with negligible power loss for arrays of elements of any kind [8]. In another approach, in order to have an antenna array with the minimum beam deviation, a 3-way SPD has been designed with a relatively large distance between the output ports [9].…”

In this paper, extended composite right/left-handed (E-CRLH) structures are studied to design multiband microwave devices. As an example, a 3-way series power divider (SPD) is designed. The overall effects of the E-CRLH structures, as the feeding networks of the antenna arrays, on the antenna arrays main beam variations are investigated. We also design and implement two antenna arrays with N = 3 elements and the same inter-element distances each fed by a distinct 3-way SPD. The radiation patterns of the antennas are examined. Simulation and measurement results demonstrate that the desired main-beam squinting of the antenna array could be obtained by engineering the parameters of the feeding network instead of adjusting the inter-element distances.

Two filtering-response power dividers embedded substrate integrated waveguide (SIW) filter are presented in this paper. By employing different SIW resonators, single- and dual-band filtering response are achieved, respectively. The even- and odd-mode method and the coupled resonator theory are applied to analyze the presented power dividers. In addition, a novel isolation technique using multiple isolation resistors is proposed to improve the output isolation performance of the filtering-response power divider with multiple resonators. To verify the proposed circuits, the single- and dual-band filtering-response power dividers are designed, fabricated and measured. Reasonable agreement between the simulated and measured results is achieved. Moreover, the measured output isolation of the fabricated dual-band filtering-response power divider with multiple resonators is about 20 dB, which demonstrates the theoretical predication.

“…So this phase shifter occupies a large space and cannot be applied in an ultra-compact antenna array. In recent years, many phase shifters based on metamaterials including composite Right/Left Handed Transmission Lines (CRLH-TLs) are proposed to reduce their sizes [12,13]. For example, a miniaturized Gysel power divider and phase shifter is realized by using CRLH-TLs implemented with lumped elements [14], in which a size reduction at least 81.8% is achieved.…”

Abstract-In this paper, an interdigital resonator that can greatly decrease mutual coupling between adjacent patches is proposed to realize an ultra-compact microstrip antenna array operating in 2.4 GHz wireless communication system. Due to its remarkable performance of decoupling, the edge to edge distance between adjacent patches can be reduced to 0.08λ 0 and even less. Meanwhile, a miniaturized feeding network, which is composed of a CRLH-TL-based phase shifter and T-junction-based power divider, is used to feed the compact antenna array. The simulation results show that the proposed antenna array has an impedance bandwidth of 8.34%. We fabricate the antenna array to verify its performance. The experimental results are in good agreements with the simulations. Compared to the published designs, the proposed antenna array has an ultra-compact structure and hence can be used in space limited communication systems.
