Single Front-End MIMO Architecture with Parasitic Antenna Elements

Single Front-End MIMO Architecture with Parasitic Antenna Elements

In recent years, wireless communication technology has been studied intensively. In particular, MIMO which employs several transmit and receive antennas is a key technology for enhancing spectral efficiency. However, conventional MIMO architectures require some transceiver circuits for the sake of transmitting and receiving separate signals, which incurs the cost of one RF front-end per antenna...

Aerial Degrees of Freedom of Parasitic Arrays for Single Rf Front-end Mimo Transceivers

The beamspace domain of parasitic antenna arrays is explored in this paper, providing the aerial degrees of freedom available for use in Multiple Input-Multiple Output (MIMO) systems. The beamspace representation allows for the design of an alternative MIMO architecture based on single radio-frequency (RF) chains, and facilitates the inclusion of MIMO transceivers in devices with strict size li...

A Stochastic Approach to Design MIMO Antenna with Parasitic Elements Based on Propagation Characteristics

This paper proposes a channel capacity maximization method for Multiple-Input Multiple-Output (MIMO) antennas with parasitic elements. Reactive terminations are connected to the parasitic elements, and the reactance values are determined to achieve stochastically high channel capacity for the environment targeted. This method treats the S-parameter and propagation channel of the antenna, includ...

An antenna solution for MIMO channels: the switched parasitic antenna

We investigate the switched parasitic antenna (SPA), which is a novel technique for electronically directing the radiation pattern, in a MIMO system. The correlation between the received signal modes are shown to be sufficiently low to yield a diversity gain. The capacity limit using the SPA is investigated for different SPA configurations and it is found that the capacity is comparable with an...
