Lefapheng la li-antenna tsa microwave, directivity ke parameter ea bohlokoa e hlalosang hore na antenna e lebisa matla joang ka tsela e itseng. Ke tekanyo ea bokhoni ba antenna ba ho tsepamisa mahlaseli a maqhubu a seea-le-moea (RF) ka lehlakoreng le itseng ha ho bapisoa le radiator ea isotropic e loketseng, e khantšang matla ka mokhoa o ts'oanang ka nqa tsohle.

Directivity vs. Gain
Hangata Directivity e ferekanngoa le phaello, empa ke likhopolo tse fapaneng. Leha directivity e lekanya bongata ba mahlaseli, phaello e ela hloko katleho ea antenna, ho kenyeletsoa tahlehelo ka lebaka la lisebelisoa le ho se tsamaisane hoa impedance. Ka mohlala, antenna e phahameng-directivity e kang parabolic reflector e lebisa matla ka har'a maballo a moqotetsane, e leng se etsang hore e be se loketseng bakeng sa puisano ea sebaka se selelele. Leha ho le joalo, phaello ea eona e ka ba tlase haeba tsamaiso ea lijo kapa **Waveguide Adapter** e hlahisa tahlehelo e kholo.
