Antenna performance parameters can be categorized into two groups: circuit parameters and radiation parameters. Circuit parameters refer to the impedance matching properties such as reflection coefficient magnitudes (|S_ii|) and isolation (|S_ij|) between the antenna ports. Antenna radiation parameters refer to radiation patterns, gain, directivity, antenna efficiency, polarization, effective length and effective aperture, antenna temperature, etc. Readers should refer to the well‐known text book by C. A. Balanis, Antenna Theory: Analysis and Design (Fourth Revised edition), Wiley publications [1] for detailed discussion and learning about these antenna performance parameters.
