Reconfigurable antennas have received much attention in the past years playing an important role in the design of smart and adaptive systems. They have been benefited from recent improvements in the performance of the existing switching technologies. In particular, integrating active devices such as MEMS switches or solid state switches in antennas and microwave circuits have been proved to be useful...
The idea of this paper is to use simple symmetrical structures offering the possibility of pattern diversity or beam switching by using various feed points. Therefore, this paper focuses on a Sierpinski shaped patch antenna, offering the possibility to adjust the main beam of the antenna in three directions by using three different feed points in one structure. In contrast to the investigations in...
Multiple-input multiple-output (MIMO) technology is a technique which can increase capacity by exploiting multiple antennas in transceivers without the need for extra spectrum or transmit power. This technique is expected to be employed in handheld devices as high bit rate intensive applications become more popular, such as internet access, high definition signal transmission or on-line gaming. However,...
