Summary:
This paper presents an analysis of the mutual interactions between holding angle and broadcasting waves polarization on the sensitivity of a 4-branch MRC array used for a digital broadcasting portable TV set. First, we have measured a way of holding a portable TV set in order to investigate statistical properties of the holding angle. Characteristics of broadcasting waves polarization are also quantitatively examined through propagation measurements. Based on the measured results, the sensitivity of an MRC array was examined to clarify the mutual interactions in terms of the radiation power ratio (RPR). The results show that the holding angle has a significant impact on the sensitivity of an MRC array, and that there is a possibility of achieving a high-performance MRC array antenna by optimizing the RPR characteristics of an MRC array.
