New Circularly Polarized Matrix Antenna For Space Applications

International audiencethis paper presents a new electromagnetic approach of matrix antenna, specialized for circularly polarized space applications. The design of the proposed antenna matrix is based on small pixels which generate circular polarization field. The concept of the pixels is well demonstrated as a patent and verified for the use in antenna arrays. The design will be used for several space applications with directive and wide angle beams. Index Terms—antenna array, axial ratio, beam forming, Isoflux, Electromagnetic band gap material EBG, Frequency selective surface FSS

An agile electronically scanned EBG matrix antenna for monitoring target activity

International audienceTelecommunications, civil and military radars, RFID (Radio Frequency IDentification) and all the radiating systems are evolving towards the spatial agility that associates « range » and « coverage ». In this context, this article describes and demonstrates an experimental prototype to show the reliability and efficiency of the EBG matrix antenna theoretical aspect, for beam forming and beam steering applications

Organizational learning, innovativeness and performance of financial service firms in an emerging market: Examining the mediation effect of customer-focused strategy

Purpose -- The study investigates the extent to which organizational learning and innovativeness can improve the firms' performance through a customer-focused strategy. Design/methodology/approach – Data was collected from Indonesian financial service firms using a questionnaire-based survey. The 157 usable survey responses were analyzed to test the proposed hypotheses using SmartPLS. Findings – This study finds that both organizational learning and innovativeness have a positive effect on performance. The effect of organizational learning on performance depends on the variations of the customer-focused strategy. However, innovativeness does not mediate through customer-focused strategy to enhance performance. Theoretical implications -- As one of the types of dynamic capabilities, organizational learning and innovativeness are also important antecedents of performance. Practical implications -- In firms that implement business model innovation, managers should focus on resource flexibility. Where it is responsive, managers need to be concerned with ensuring various usage of existing resources to understand the performance effectively. Originality/value -- This study extends the business innovation model from the adaptability of customer-focused strategy. The findings confirm that organizational learning has a prominent role in meeting customer needs for a dynamic market
