Miniature Multi-Element Antenna for Wireless Communications
We present a novel broad-band miniature antenna and employ it in a multi-element geometry with diversity capabilities for wireless communications. This antenna (diameter 0.2 and thickness 0.06 ) consists of two stacked circular patches that create two cylindrical slots resonating at two slightly different frequencies, fed by a strategically positioned coaxial probe. An extensive parametric stud...
متن کاملReconfigurable Miniature Multielement Antenna for Wireless Networking
Abstract 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. Two antenna geometries are considered. A single element antenna, the socalled dime antenna, is introduced. A prototype dime anten...
متن کاملA Packaged Miniature Antenna for Wireless Networking
A novel miniature antenna structure (approaching the smallest fundamental size limits) having numerous qualities such as low cost, efficient circuit (broad bandwidth) and radiation characteristics (suitable for wide angular coverage) has been developed. Owing to its very small size and radiation performance, it is compatible for packaging constraints and can be easily integrated in a big variet...
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 کاملMultiple-Antenna Techniques for Wireless Communications
multiple-input multiple-output (MIMO) techniques to improve the robustness and performance of wireless links. Here, the term multiple-input multiple-output refers to the use of an array of antennas for both transmitting and receiving. MIMO approaches show promise of enabling better wireless communications because they mitigate problems inherent in ground-to-ground links, which are the most comm...
