Ultra-wideband wireless communication technology is brought, in the coal mine communications in this paper in order to raising the safe level of communication in coal mine. Ultra-wideband wireless communication is a system which is transmitted by the extremely narrow pulse transmission. An avalanche transistor is the core of extremely narrow pulse circuit. Narrow pulse wave form can be simulated by multisim software. Acquiring the results of simulation is the extremely narrow pulse whose pulse amplitude ranging from 10 v to dozens v and pulse width is about 3 seconds. In addition to this circuit carries on the theoretical analysis, the results is quite consistent with the simulation value in this paper.

Matrix Analysis and Pulse Transmission of Antenna Array for MIMO UWB Systems This paper presents a theoretical matrix analysis of antenna structure consisting of two double-element planar antennas for ultra-wideband (UWB) application in 2*2 MIMO indoor communication systems. The structure and characteristics of pla-nar two-element UWB antenna are presented. Two matrix models of MIMO antenna system are represented in the paper. A stan-dard MIMO signal transmission matrix without taking into con-sideration the coupling between antennas is described. A new ap-proach to a full electromagnetic analysis based on the scattering matrix of the MIMO spatial antenna array is proposed. Func-tional power parameters for the whole MIMO UWB transmit-receive antenna structure are introduced. Results of computer si-mulations of different matrices describing a MIMO antenna sys-tem and the transmission propagation pulses are presented.
