We report on a combined approach to solve two known problems of traditional Explanation-Based Generalization (EBG) concerning utility and expressiveness. (1) Usually, for each training example a new rule is derived and added separately. Therefore, the overall performance of the associated inference system may degrade if the presented instances are numerous and not representative for the class o...

The traditional coplanar electromagnetic bandgap (EBG) structure is analyzed. The method is studied to lower the center frequency and broaden the bandwidth in this paper. A novel structure of U-bridged EBG power plane is proposed. The simulation and test results show that the bandwidth of the new structure is 4.32GHz, and the lower side cutoff frequency is at 380 MHz with the stopband depth at ...

Microstrip patch antenna becomes very popular day by day because of its ease of analysis and fabrication, low cost, light weight, easy to feed and their attractive radiation characteristics. Although patch antenna has numerous advantages, it has also some drawbacks such as restricted bandwidth, low gain and a potential decrease in radiation pattern. In recent years, attention to use Electromagn...

In Antenna Technology, Electromagnetic Band Gap (EBG) structures are one of the mostly used to improve gain antenna, suppress surface waves and band notching. UWB frequency spectrum more number small bands exists these cause electromagnetic interference, reject such EBG required. Due limited monopole antenna's ground plane, it is required have with in size single two or bands. The simulated res...

An important issue in antenna array design is reduction of mutual coupling. In microstrip antennas this reduction can be achieved by using electromagnetic band-gap (EBG) structures. These structures prevent the propagation of surface waves on the substrate of a microstrip antenna array. This paper presents a new configuration of a planar compact electromagnetic bandgap structure to reduce mutua...

This paper demonstrates the advantages of magnetic loading within the substrate of an electromagnetic bandgap (EBG) surface. A conventional EBG surface has been shown to act as an artificial magnetic conductor over a narrow bandwidth. This paper demonstrates that by magnetic loading of the substrate, increased operating bandwidth is achieved for each resonant frequency. In addition, previous re...
