So if I measure the null-to-null spacing in the S11 plot from a non-50 ohm transmission line and then calculate the delay using your formula given earlier: delta f in GHz) = 1/(2*Td) is Td also the group delay? Will a non-consistent group delay issue show up as variation in the measured S11 null-to-null spacing?
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
