The objective of this paper is to analyze the performance of electromagnetic band gap (EBG) antenna for base station applications through simulation. The proposed analysis is carried out using the high frequency structure simulator (HFSS). In our method, to overcome several intrinsic limitations of patch antennas such as constrict bandwidth, low gain, excitation of surface waves, the EBG concep...

On a multi-antenna downlink channel, separation of multiple users by transmit beamforming enables simultaneous transmission from the base station to the users, resulting in very high throughput. This paper proposes and analyzes a practical scheme for joint orthogonal beamforming and scheduling, which is enabled by feedback of quantized channel state information. In this approach, the base stati...

The impact of base station antenna height and antenna tilt on SINR in LTE systems have been discussed in this paper. Vienna LTE system level simulator has been used to obtain the results for studying the performance of LTE systems. Results highlight the point that changes in antenna height and tilt angle results in variations in the signal coverage and path loss of the network which in turn var...

In this paper, we use the shooting and bouncing ray/image (SBR/Image) method to compute the path loss for different outdoor environments in the commercial area of Taipei. Three types of antenna arrays such as L shape, Y shape, and circular shape arrays are used in the base station and their corresponding path loss on several routes in the outdoor environment are calculated. Moreover, the geneti...

Wireless systems have recently been becoming faster and more intelligent. However the high speed access and intelligence make the power consumption of wireless systems high. In the WiMAX system, the MS transmission power is controlled in order to avoid exceeding the BS’s total receiving power from an antenna. Conventional wireless network design has long used base site sectorization and single,...
