Definisyon: vòltaj antèn siyal opinyon ak rapò siyal kounye a, li te ye kòm enpedans nan opinyon antèn. Rin gen yon eleman resistive nan enpedans nan opinyon ak eleman reaktans Xin, sètadi Zin lan = rin + jXin. Eleman reaktans nan antèn lan ap diminye prezans la ki gen pouvwa siyal soti nan feeder nan fè ekstraksyon a, se konsa kòm yo fè eleman nan reaktans se zewo, se sa ki, osi lwen ke posib yo enpedans nan opinyon antèn se piman resistive. An reyalite, menm desen an, debogaj antèn trè bon, enpedans nan opinyon gen ladan tou yon ti valè reaktans total.

Definition: antenna input signal voltage and signal current ratio, known as the antenna input impedance. Rin has a resistive component of the input impedance and reactance component Xin, namely Zin = Rin + jXin. Reactance component of the antenna will reduce the presence of signal power from the feeder to the extraction, so as to make the reactance component is zero, that is, as far as possible to the antenna input impedance is purely resistive. In fact, even the design, debugging very good antenna, the input impedance also includes a small total reactance values.
