International Conference on Microwave and Millimeter Wave Technology Proceedings

作者： Gui Wang Rushan Chen Wanchun Tang School of Electronic Engineering and Optoelectronic Technique Nanjing University of Science and Technology of PLA Nanjing China

Coplanar waveguides on silicon substrate were simulated. Using MEMS (micro-electro-mechanical system) technology, the V-shaped and W-shaped groove coplanar waveguides were implemented on silicon substrate, and its characteristic impedance was 30Ω, 50Ω, 75Ω and 100Ω respectively. In addition, the characteristic impedance of coplanar waveguide (CPW) was analyzed, and the conclusion was used to guide the design of MEMS CPW. According to the measurement results, insertion loss of coplanar waveguides was below 1dB/mm. If it is fabricated with lower resistivity metal, the insertion loss will be decreased.

In this paper, parallel-distributed block latency insertion method (block-LIM) is proposed for the fast transient simulation of the large scale circuit which includes lots of coupling elements such as mutual inductance and mutual capacitance. First, the block-LIM formulation for the network with mutual inductance and mutual capacitance is shown. Next, the parallel-distributed block-LIM is described. Finally, some numerical results are shown and it is confirmed that the proposed technique is useful and efficient for the simulations of the tightly coupled transmission lines.

The design of transmission lines (TL) is usually based on conservative aspects, in order to meet with safety standards and avoid the deterioration of line construction materials. With the increasing demand for energy, the idea of improving the transmission capacity of already existing lines, designed in a high safety manner, is attractive; instead of duplicating or constructing new ones. A piece of equipment for monitoring current and temperature in 138 kV transmission lines using photonic power and data communication is presented; providing information for a sag-current relation, and consequently a safer ampacity sizing, while a full operation of the line is being carried out. The power supply for the sensors and data processing circuits in high voltage area is provided by photonic energy, transmitted through an optical fiber. Likewise, the measured results are sent to the low voltage area using another optical fiber, achieving good electrical safety.

Basic left-handed transmission line (LH-TL) characteristics made on PCB is an important future issue for the application of the EMC field. In this paper, possibility of transmission line with negative group delay characteristic in an integrated circuit is investigated experimentally and numerically. The measured and simulated results demonstrated the usability of the LH-TL. The experimental results indicate some negative group delay characteristic but the differences with the calculation is still existed at higher frequencies.

This paper deals with the development of a time-domain full wave simulation tool for Very Low Frequency/Low Frequency antennas taking into account the surrounding components such as insulators. To overcome very large multi-scale problems involved with VLF/LF radiating structures, an efficient 3D arbitrarily oriented wire node was implemented in the TLM method in. The implementation of insulators as lumped component in this 3D wire model is now proposed. The insulator electric parameters were derived from simulation results of the field distribution along insulators, presented in.

To address the problem of lightning struck on overhead transmission lines, a kind of jet stream interrupter gap lightning protection device (JSIGLPD) installed in the overhead transmission lines was developed. When lightning struck on the transmission line and cause AC flashover of insulator strings, the device is able to quickly cut off the frequency freewheeling, and effectively protect the insulator strings against ablation of frequency electric arc. The JSIGLPD can achieve the function of limiting the external over-voltage on insulators and avoiding frequent tripping of circuit breaker. This paper studied the movement characteristics of electric arc under the conditions of jet stream based on the chain arc model and shock wave theory, and discussed the arc quenching process.

An overhead transmission line temperature-rising method based on parallel capacitor compensating reactive power source is proposed. The method is based on the characteristics of sinusoidal AC and the theory of parallel capacitor compensating reactive power source within electric power grid. The theoretical derivation and wiring diagram of this method is given in this paper. The novel temperature-rising method is based on inputting reactive current at the terminal of transmission line. The probable conditions of system resonance caused by parameters variation during the overhead transmission line temperature-rising operation is analyzed theoretically and the resonance suppression measures and methods are given. Through the on-site thermal experiment of lOkV power transmission line, the real-time data of the current I, active power P and reactive power Q are obtained, which verifies the theoretical efficiency and feasibility of the temperature-rising method.

Left-handed materials are commonly analyzed by using frequency-dependent parameters that include regions of negative permittivity and negative permeability in Maxwell's equations. An alternative approach is presented where both right-handed and left-handed behavior are supported by augmenting Maxwell's equations with additional terms. The proposed equations exhibit typical metamaterial behavior, including frequency bandgap and dispersion.

Transmission line model for meander antennas

Transmission line model for meander antennas

European Conference on Antennas and Propagation, EuCAP

作者： O. Losito M. Gallo V. Dimiccoli D. Barletta M. Bozzetti ITEL Telecomunicazioni S. r. l. Bahia Italy

Nowadays valuable and efficient numerical methods allow an empirical approach in the design of antennas for high-frequency wireless communication systems. Generally these numerical techniques apply either time- or frequency-domain algorithms demanding high computational efforts and long-time processing. Moreover, the initially assumed geometrical configuration can strongly affect the numerical convergence efficiency. With reference to a meander antenna, this paper highlights the computational improvement achievable by applying a transmission line model to the definition of an initial geometry, to be numerically optimized, the sizes of which are nearly to the final ones.

Microwave, MTT-S International Symposium

作者： Charles J. Trantanella Custom MMIC Design Services Westford MA USA

In this paper, we present a novel power divider with enhanced physical and electrical port isolation as compared to a standard Wilkinson divider. We obtain the improvement by placing the isolation element between the λ/4 high impedance transmission lines at an arbitrary phase angle, Θ, instead of Θ=90° as in the standard Wilkinson divider. As a result, the outputs of our new divider are both physically and electrically isolated. We first develop the theoretical relation between Θ and the required isolation elements. We then demonstrate the performance of our new divider in MMIC form by comparing its simulated and measured performance to a conventional Wilkinson power divider.
