Obstacle Detection with 77 GHz Automotive Radar

One of typical applications of EM tools in automotive radar industry would be accurate prediction of radiation pattern of automotive radar antenna mounted on the front part of a car. Also, near field distribution in front of the car shell (usually in presence…

Determining a resonant frequency of a cavity is a frequent task in analyzing various microwave systems. Due to the shape and interior structure of the cavity, it is often not possible to perform resonant frequency calculations by applying analytical formulas. In such cases, direct…

Simulation of reflector antennas can be very challenging for MoM codes. Despite that, WIPL-D Software, as MoM code based on SIE, appears to be very suitable and efficient tool used for simulating large reflector antennas. Reflector, as part of the…

This paper presents the procedure for the design of Cassegrain reflector antenna. It contains theoretical consideration and foundation, as well as procedure for design in the WIPL-D software suite. Cassegrain reflector antenna consists of two parts: feeding conical horn with hyperbolic sub-reflector, and main parabolic…

This note explains how to analyze and optimize a general differential microwave circuit using WIPL-D design environment. Weather it is the circuit or EM component the differential/common mode analysis can be carried out within WIPL-D Microwave Pro by adequate connection of several transformer elements…

A magnetic antenna system, which has been patented by G. Wennerberg, could be efficiently used as a direction-finding antenna (DFA). This magnetic antenna system represents an improved magnetic antenna, especially suitable for mounting on an aircraft as it does not…
