This paper presents an antenna design method for a dual antenna with high isolation for mobile stations (MS) and includes a verification method for improving the correlation performance of an MS that uses a proposed Multiple-Input Multiple-Output (MIMO) antenna by using MIMO OTA channel models. The large scale parameters for the MIMO OTA channel models are important because they determine the fixed geometrical parameters to be used for channel impulse response realization. The correlation performance of an MS has a strong relation to the Cross Polarization Discrimination (XPD) of the second branch antenna both numerically and experimentally. This study applies modern technology to implement MIMO antenna switch high isolation by selecting Band 5 to have low frequency, fabricated antenna samples that have several XPD values, thereby comparing their characteristics.
This article empirically analyzes a model of knowledge transfer activation based on trade in knowledge market perspective. We aim to provide insights into trade in the knowledge market through an empirical analysis. Using a research model with a theoretical basis on knowledge sharing culture and trade in knowledge market, we conducted an empirical study using data on enterprises' knowledge management systems (KMSs). The results revealed that 62.6% of the variance in knowledge transfer activation was explained by the items of knowledge organization, knowledge strategy, KMS, and knowledge reward through knowledge sharing culture and trade in knowledge market. This suggests that horizontal organization and a strategy that pursues an organization's objectives positively impact knowledge sharing culture, while knowledge technology (KMS) and reward positively affect the trade in knowledge market. We therefore conclude that trade in knowledge market is an important factor to activate knowledge transfer. This article contributes to lay the foundation for future work on empirical study of knowledge transfer based on trade in knowledge market.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
