 note = {3種のアンテナ設置位置にて偏波特性を測定した．この測定により，XPD特性の車載受信アンテナの設置状況への依存性を明らかにした．また，2つの偏波を理想的に受信して利用できると仮定した利得を評価した．これは，最大比合成のダイバーシチ利得に相当する．そのため，実測データを用いて，空間ダイバーシチと偏波ダイバーシチの利得を評価した．これらを踏まえて，アンテナ設置状況に着目した水平偏波の有効性について考察する．, We carried out measurements of the received power at three different antenna positions. By the measurement, we clarified the dependency of the XPD characteristics on the installation situation of a receiving antenna in a vehicle. We also evaluate the gain where the dual polarizations are ideally received and utilized. It is equivalent to the diversity gain of the maximal ratio combing. Therefore, using the measured data, we evaluated the gain of the space diversity and the polarization diversity. Based on these considerations, we discuss the effectiveness of the horizontal polarization focusing on the antenna installation situation., application/pdf},
