Featured Examples

Design and Analyze Curved Reflectors

Design and analyze the curved reflectors. Curved reflectors are an upgraded version of rectangular reflectors. The curved surface on these reflectors reflects and focuses waves, which provides a stronger signal. Some of the notable characteristics of the curved reflectors are high gain, low cross-polarization, and reasonable bandwidth.

Reflector Backed Equiangular Spiral

The spiral antenna is an inherently broadband, and bidirectional radiator. This example will analyze the behavior of an equiangular spiral antenna backed by a reflector [1]. The spiral and the reflector are Perfect Electric Conductors (PEC).
