Multibeam Antennas With Polarization and Angle Diversity
نویسندگان
چکیده
A 10-GHz discrete cylindrical lens array with multiple beams is designed and characterized as a receiving angle-diversity array for wireless communications in a multipath environment. The array also has dual-orthogonal polarization and therefore built-in polarization diversity. The array is designed for wide-angle scanning between 45 and 45 and measured scanning patterns are presented. The polarization isolation between the two channels is about 30 dB at boresite and about 10 dB for a 30 scan angle. The addition of the lens array at the very front end of a link shows significant reduction of multipath fading peak-to-null ratio.

This paper considers transmit diversity schemes applied to cross-polarized linear antennas at cellular basestations, with a single linearly polarized antenna used by the mobile station receiver. The performance of SpaceTime Block Code (STBC) and Time-Delay Transmit Diversity (TDTD) is analyzed as a function of the relative orientation of the transmit and receive antennas. It is shown that power...
متن کاملDesign and Efficient Analysis of Large Reflectarray Antenna
In recent years reflectarray antennas have received considerable attention due to their unique capabilities. However, due to their large size, analyzing the performance of these antennas using traditional full wave finite-difference and finite-element techniques requires considerable computational resources. In this paper, we present an efficient method to accurately analyze these class of ante...
متن کاملMiniature Multielement Antennas for Diversity Wireless Communications
We present a new reconfigurable broadband miniature antenna architecture that is able to change its working frequency, polarization, or radiation pattern to get single broadband or dualband behavior for a single widebeam or multibeam diversity configuration. First the basic so-called “dime” geometry is introduced. Numerical and experimental results for a prototype at 5.2 GHz are presented. Base...
متن کاملMultibeam antennas for indoor wireless communications
A multibeam beamformer in combination with a decision feedback equalizer is considered for the base station in a single-cell 100-Mb/s TDMA/TDD QPSK indoor wireless network at 24 GHz. The outage rate in terms of required SNR/bit/antenna is estimated using a statistical, clustered propagation model and for beam selection diversity and two-beam combining.
متن کاملDesign of dielectric lens antennas by multi-objective optimization
Lens antennas are a promising device for realizing the anti-collision radars needed in intelligent transport systems (ITS) and multibeam antennas for satellite communication. They have simple structure, high gain and no feed blockage. Especially if the operating frequencies are above the microwave band, the resulting apertures with several tens of wavelengths, become practical. In advance ITS a...
