Phased array antenna using MEMS phase shifter
This article presents a phased array antenna employing MEMS phase shifter. The proposed phased array antenna consists of eight square patch antennas operating at 10.4 GHz with a bandwidth of 400 MHz. Feed line for each patch passes through a MEMS phase shifter realized by a series of bridges above the transmission line. The distance between the bridge and the transmission line underneath it is ...
متن کاملFrequency-Domain Adaptive Antenna Array for Multi-Code MC-CDMA
MC-CDMA is an attractive multi-access method for the next generation high-speed mobile communication systems. The uplink transmission performance is limited by the multi-access interference (MAI) from other users since all users share the same bandwidth. Adaptive antenna array can be used to suppress the MAI and to improve the uplink transmission performance. In this paper, we propose a frequen...
متن کاملRobust Antenna Array Beamforming under Cycle Frequency Mismatch
Many algorithms exploiting the signal cyclostationarity have been shown to be effective in performing antenna array beamforming. However, these algorithms can not provide a unique weight vector for simultaneously extracting multiple signals of interest (SOIs) with distinct cycle frequencies (DCFs). They also suffer from severe performance degradation in the presence of a cycle frequency error (...
متن کاملModeling Frequency Reconfigurable Antenna Array Using Neural Networks
In order to avoid the computational complexities involved in analyzing reconfigurable antennas, neural networks are used as an alternate approach. The neural network finds the location of the operational frequency bands for any combination of switches connecting different radiating elements. The network outputs are compared with the experimentally measured results. © 2005 Wiley Periodicals, Inc...
متن کاملFrequency Domain Adaptive Antenna Array for Single-Carrier Uplink Transmission
In this study, we present a single-carrier frequency domain adaptive antenna array (SC-FDAAA) scheme for the uplink transmission and apply the SC-FDAAA scheme to single cell and cellular distributed antenna network (DAN) as well. It is shown by simulation results that the SC-FDAAA scheme can effectively suppress the interfering signals in a severely frequency selective fading channel both in th...
