Novel Antenna System Design Paradigm for High Performance Mobile Communications

Abstract:
|
State-of-the-art antenna design typically focuses on fulfilling some prescribed performance criteria, such as efficiency, bandwidth and directivity. Even though these may be derived from the antenna´s operating environments, there has been little attempt or motivation to explicitly consider antennas in optimizing system level performance.
However, increasingly challenging design goals in future wireless communication systems together with promising new technologies call for a more holistic approach in antenna system design. The so-called multiple-input multiple-output (MIMO) technology that utilizes multiple antennas in both transmitter and receiver is a case in point.
In this project, the main objective is to address two fundamental limitations in future mobile communications which employ MIMO technology using the new paradigm of optimizing antenna systems from a system perspective.
Firstly, apart from high correlation and mutual coupling among closely spaced antennas, user terminals are required to operate under a variety of propagation and user environments. Secondly, signals arriving at base station antennas typically have narrow angular spread, which result in high correlation.
A common strategy will be applied to mitigate these limitations: (1) understand the underlying physics and performance limitations based on theory, simulation and experiment; and (2) achieve near optimum system design using practical antenna system design
strategies.
