The basic scattering theory of single-port antenna is illustrated in both the frequency-domain and time-domain clearly

in this paper.The polarizations of detecting antenna

detected antenna

and receiver antenna are included in the analytical course.The structural mode scattering and the antenna mode scattering are separated in the time-domain intuitively.Based on the analysis procedure above

some basic approaches of controlling antenna scattering are given.This work will serve as a good candidate for the future design of antennas with a requirement of scattering control.
