Radar and Radio Systems Coverage Optimization

Radomes are a key part of antenna systems, which can seriously degrade transmitted and received signals. Modeling and simulation time for complex radomes can extend from days to weeks, and that also includes FSS structures embedded into them.

Safe and compliant electronic system design is important across all industries. Conforming to EMC regulations while reducing development costs and time requires the implementation of simulation throughout the product design lifecycle. With increased adoption organizations reduce design iterations and costly laboratory testing while meeting targets.

This insight aids in choosing the locations of the excitations on the antenna and of the antennas on the platform. Furthermore, knowledge of the coupling between excitations and modes enables the design engineer to synthesize the desired antenna pattern by exciting a linear combination of modal patterns. This webinar presents the applicability of CMA to antenna design with examples.
