Description/AbstractThis paper provides the essential tools for deriving quickly the quasi-thermal noise spectrum or the impedance of a given electric antenna near the plasma frequency, for calibration or diagnosis in space plasmas. The authors give simple analytical expressions and numerical results for either wire or sphere dipoles in an isotropic plasma with one or two Maxwellian electron populations. They include the contribution of the particles collected and/or emitted by the antenna surface. They also indicate some modifications brought about by using more complicated antenna geometries, and a drifting or a magnetized plasma. Finally, they give some conclusions for antenna design or data interpretation in plasma wave experiments.
