摘要
Wireless world initiative new radio (WINNER) delivers a 3D cross-polarized channel model for B3G/4G system designs. Comprehensive radiation characteristics of polarized antenna are crucial in generating channel coefficients. Being currently supported within WINNER channel model, field patterns are technically obtained by chamber measurement. However, in some channel related performance analysis scenarios, design insight can be crystallized better by starting the derivations with theoretical co-pol and cross-pol components. Specifically, these two components are mathematically linked with field patterns through the proposed polarization projection algorithm. In this paper, we focus on revealing the physical significance of polarization transform between the antenna plane and the propagation plane. In practice, it makes retrieving the field patterns by electromagnetic computation possible. Meanwhile, the impact imposed by distinct antenna orientations is geometrically illustrated and consequently incorporated into the proposed algorithm. The result is analytically verified by the closed-form expression of the dipole field pattern and we find that its 2D degenerative case is aligned with that defined in 3GPP TR 25.996. The benefit is to significantly reduce the cost on generating channel coefficients in WINNER channel simulations.
