TL;DR: In this paper, a compact-size coplanar waveguide (CPW) bandpass filter (BPF) is proposed, which reduces the dimension of the circuit by 66.67% at 2.45 GHz.
Abstract: A compact-size coplanar waveguide (CPW) bandpass filter (BPF) is proposed. In this study, we use the bended stub with novel folded skill to improve the three parallel coupled-lines structure of BPF for N = 1. It gets the sharp transition band (TB) and reduces the dimension of the circuit by 66.67% at 2.45 GHz. Its center frequency can be shifted easily by adjusting the interfaces of SS and S'S' simultaneously. It is very useful for applications in the wireless communication systems.

TL;DR: In this article, a novel shunt-stub Wilkinson power divider with uniform impedance line is proposed, which is quite suitable for unequal power dividers, especially for the case of high distribution ratio and large power capability.
Abstract: A novel shunt-stub Wilkinson power divider with uniform impedance line is proposed. Compared with conventional Wilkinson power divider, the output distribution ratio of this novel divider is controlled by the length of shunt stubs. It is quite suitable for unequal power divider, especially for the case of high distribution ratio and large power capability. Explicit deductive equations, equivalent circuit models and design parameters for this novel shunt-stub power divider are derived. Finally, the proposed structure is used to construct three power dividers whose distribution ratio are, respectively, 6:1, 4:1 and equal split. Measured results show good agreements with simulations and denote the applicability in practical engineering.

TL;DR: An analytical approach, based on the Green's function method, is developed in order to investigate electromagnetic wave transmission across SPPs MIM waveguide networks and shows excellent computational efficiency in contrast with solving Maxwell equations numerically.
Abstract: Metal-insulator-metal (MIM) surface plasmon polaritons (SPPs) waveguides with side-coupled resonators have been widely studied through various approaches. However, few methods are both physically transparent and complete. Here, an analytical approach, which is based on the Green’s function method, is developed in order to investigate electromagnetic wave transmission across SPPs MIM waveguide networks. The proposed method is applied in order to model different MIM-waveguide geometries with weakly-coupled side stubs, comparing to the geometries with strongly-coupled stubs. The weak coupling between the backbone and stubs is taken into account by the electromagnetic field leakage at metal-insulator interface. Analytical expressions for transmittance in cases of single stub and cavity are obtained straightforwardly. Our method shows excellent computational efficiency in contrast with solving Maxwell equations numerically.

TL;DR: In this paper, a reconfigurable dual-mode ring resonator matched bandstop filter with PIN diodes as switching elements is presented. But the performance of this filter is limited to 1 GHz.
Abstract: This paper demonstrates a reconfigurable dual-mode ring resonator matched bandstop filter. The dual-mode ring resonator structure is composed by two degenerate modes or splitting resonant frequencies using a perturbing stub. The reconfigurable dual-mode ring resonator matched bandstop filter is realized by using PIN diodes as switching elements. This reconfigurable filter provides two states of operation; allpass and bandstop response. Frequency of 1 GHz is chosen to demonstrate this operation. The theoretical analysis together with simulation and measurement results are presented in this paper. As a result, this filter can be reconfigured between allpass and bandstop using PIN diodes at 1 GHz.

TL;DR: An antenna on a printed circuit board (PCB) with a compensating capacitor is discussed in this paper, where the antenna has a radiator disposed over a first surface of the PCB, where the tuning section includes a bending portion.
Abstract: An antenna on a printed circuit board (PCB) with a compensating capacitor. The antenna has a radiator disposed over a first surface of the PCB. Wherein the radiator includes a signal feeding section and a tuning section coupled together at a joint. The tuning section includes a bending portion. Also and, a ground layer with or without a protuding portion is disposed on a second surface of the PCB, wherein the bending portion of the tuning section is overlapping with the ground layer to form the compensating capacitor. In addition, the radiator can also have a short circuit stub section, electrically coupled to the ground layer.
