The Filtering Performance of a Kind Antenna Model

This paper investigates the filtering performance of a new kind of compact antenna model, the cube antenna model. At first, the explicit expression for the signal to interference-plus-noise ratio (SINR) is obtained in terms of the parameters of the signal, interference, and noise. Then the filtering performance is simulated with Matlab simulation software. The results show that this antenna model has an excellent filtering performance in Polarization Domain, which makes up the limitation of the traditional Adaptive Array Antenna (AAA). Comparison with the polarization-sensitive-array (PSA) presents that the cube antenna model does not only performs well in Space Domain but also more even in different directions. Moreover, this compact structure can be used in a much smaller volume. All these results demonstrate that the cube antenna model has an outstanding performance both in Space and Polarization Domains. as illustrated by the portions given in this document.
