Application of Impedance Extension Method to 2D Large-scale Periodic Array Antenna with Faulty Elements

چکیده
The impedance extension method (IEM) has been proposed so far, as a method for analysis of a huge-scale periodic array antenna for power transmission from space solar power systems (SSPS) to the earth[1][2]. Since the IEM is an approximate method based on active impedance properties of elements in the periodic array antenna[3], the IEM can only be applied to the periodic array antenna. However, periodicity of the array antenna can not be kept in the areas where antenna elements are broken due to the trouble in feeding circuits or feeding cables. In this paper, it is reported that the IEM is extended to be valid to a two-dimensional large-scale periodic array antenna with faulty elements.

Statistical Analysis of Huge-Scale Periodic Array Antenna Including Randomly Distributed Faulty Elements
On the huge-scale array antenna for SSPS (space solar power systems), the problem of faulty elements and effect of mutual coupling between array elements should be considered in practice. In this paper, the effect of faulty elements as well as mutual coupling on the performance of the huge-scale array antenna are analyzed by using the proposed IEM/LAC. The result shows that effect of faulty ele...

An extreamly large scale periodic array antenna is required for transmitting power from space solar power systems. Analysis of the huge-scale array antenna is important to estimate the radiation property of the array antenna, but a full-wave analysis requires too much computer memory and excessive CPU time. In order to overcome these difficulties, the impedance extension method is proposed as a...

This paper presents a new approach for design of the log-periodic dipole array antenna (LPDA) based on using of different design parameters in the LPDA elements to control the antenna behavior. In the proposed procedure, the design parameters can control the value of forward gain over the operating frequency range, and also adjust the gain flatness. Furthermore, this design procedure can decrea...
