Compact UWB MIMO Ground Linearly Tapered Slot Antenna Decoupled by a Stepped Slot

A very compact ultra-wideband (UWB) multiple-input-multiple-output (MIMO) ground linearly tapered slot Antenna (LTSA) is presented in this paper. On a cost-effective FR4 substrate, it consists of a ground plane and two microstrip feedlines. Its overall dimension is only 22 × 26mm2. To miniaturize the dimension of the antenna, two linearly tapered slots on the ground plane act as the main radiat...

Novel Resonant Converter Topology Realized by Adjusting Transformer Parameters

This paper shows a new direction as to how the transformer parameters may be best utilized and presents the performance and control of novel DC/DC and AC/DC converter topologies. All the three inductances of a transformer have been utilized to realize a CL topology having excellent characteristics and requiring no external inductor. For half bridge topology the capacitor used for the purpose of...

Adaptive MIMO Antenna Selection

The performance of multiple-input multiple-output (MIMO) systems can be improved by employing a larger number of antennas than actually used and selecting the optimal subset based on the channel state information. Existing antenna selection algorithms assume perfect channel knowledge and optimize criteria such as Shannon capacity or various bounds on error rate. This paper examines MIMO antenna...

Compact MIMO antenna design

This paper provides experimental and implementation details for various forms of multiple-input multiple-output (MIMO) cube antennas. Slot dipole antennas are used as basic elements of these MIMO antennas. Experimental results show that especially at higher frequencies of various wireless applications the additional loss of the printed antennas increase and therefore implementation of such ante...
