A two-dimensional (2D) diffraction model for the calculation of the diffraction field in 2D space and its applications to terahertz parallel-plate waveguide power splitters are proposed in this paper. Compared with the Huygens-Fresnel principle in three-dimensional (3D) space, the proposed model provides an approximate analytical expression to calculate the diffraction field in 2D space. The di...

In wireless communication systems antenna diversity is an important technique to combat multipath effects of fading to improve the system performance and to increase the channel capacity. This paper explores receiving antenna diversity issues for Orthogonal Frequency Division Multiplexing (OFDM) in Rayleigh fading environment using maximal ratio combining (MRC). The performance of MRC for OFDM ...

Antenna is a means for radiating or receiving or transmitting energy an antenna is used in an advanced wireless system is usually required to optimize the radiation energy in same direction and suppress it in others. A microstrip patch antenna, also referred to as patch antenna is a narrowband, widebeam antenna fabricated by etching the antenna element patch in metal trace bonded to an insulati...

This paper represents design methodology of novel phased array antenna and its radiation pattern of 100 elements linear phased array for highly efficient microwave power transmission (MPT) which will be focused on ground based receiving station for microwave power transmission from Space Solar Power Satellite (SSPS) system. Taking different ratio between antenna element spacing, d and wavelengt...

Channel capacity of indoor Multi-input Multioutput Space Division Multiplexing (MIMO-SDM) with antenna selection diversity is analyzed using the ray tracing method. A large number of receiving antennas are divided into several blocks. Each block is corresponding to a receiving MIMO channel, and the number of transmitting channel is assumed to be equal to the number of receiving channel. The num...
