“…Even more, there is a constant and intensive development of adaptive antenna models [13][14][15]. In addition to the aforementioned benefits, extended range and gap filling can be dealt with, when an adaptive antenna is implemented at the base station.…”

Abstract-Mobile broadband communication is experiencing rapid growth in the following sections: technology, range of services and marketing target groups. This growth has driven research and development activities towards advanced high-data-rate wireless systems, with improved network performance. A typical example of technology thrust in wireless communications is the use of adaptive antennas at the transceivers, in association with advanced array signal processing. Although the mass deployment of adaptive array systems has not achieved the desired levels yet, there are many examples of improved cell coverage, link quality and system capacity at several networks. The performance of a six-beam switched parasitic array, in terms of carrier-to-interference ratio (CIR) measurement at the uplink direction, is presented in this paper. The switched parasitic array is designed with the aid of the method of genetic algorithms and the simulation results are compared with respect to those obtained when an omni directional antenna is used instead. The calculated CIR improvement reveals the superiority of the adaptive system compared to the conventional one.

“…However, with the multiplication of the number of access points and users, the capacity of wireless networks is becoming interference-limited rather than noise limited. The use of multi-sector antennas, comprising several narrow beams, can help to solve the interference issue while improving the wireless range or/and bit rate [1][2][3][4][5].Various multi-sectored antennas have been designed and produced in the past recent years based on an omnidirectional antenna by altering the environment [1][2][3] or the power supply [4]. Another widespread technique consists in using a dedicated antenna for each sector [5][6][7], space division into multiple sectors.…”
