Design of Broadband Polarization Diversity Antenna for Mobile Base Stations

Design and Analysis of Polarization Diversity Antenna for Mobile Terminals

© 2014 Won-Woo Lee and Byung-Ho Rhee 155 http://dx.doi.org/10.4218/etrij.14.0213.0280 This letter presents an antenna design method for an orthogonally-polarized dual antenna for use in mobile stations (MSs) and includes a verification method for improving the link-level throughput performance of an MS that uses a proposed multiple-input multiple-output antenna. The link-level throughput perfor...

Exploiting Phase Diversity for CDMA2000 1X Smart Antenna Base Stations

A performance analysis of an access channel decoder is presented which exploits a diversity gain due to the independent magnitude of received signals energy at each of the antenna elements of a smart-antenna base-station transceiver subsystem (BTS) operating in CDMA2000 1X signal environment. The objective is to enhance the data retrieval at cellsite during the access period, for which the opti...

An Electrical Beam Tilt Array Antenna for Mobile Base Stations

A base station antenna is an RF component capable of critically affecting performance of a cellular system. Down tilting base station antennas is used in mobile communication to prevent co-channel interference. In this paper, we introduce antenna configuration for electrical downtilt. Here a genetically optimized technique is employed. Printed circuit dipoles are employed as radiation elements.

Safety Issues of Mobile Phone Base Stations

Optimum Design of Doherty RFPA for Mobile WiMAX Base Stations

RF power amplifiers in mobile WiMAX transceivers operate in an inherently nonlinear manner. It is possible to amplify the signal in the linear region, and avoid distortion, using output power back-off; however, this approach may suffer significant reduction in efficiency and power output. This paper investigates the use of Doherty techniques instead of back-off, to simultaneously achieve good e...
