Abstract (en)
Directional antenna (100), comprising at least:- a first radiating element (1) and a second radiating element (2) arranged spaced apart from each other at a predetermined first distance (D1);- a supply circuit (5) which is connected to and is adapted to supply said first and second radiating elements (1, 2) with a feeding signal to be radiated, wherein said supply circuit (5) comprises at least one conducting element (5a) having a first end (5b) connected to the first radiating element (1) and a second end (5c) connected to the second radiating element (2), said at least one conducting element (5a) having, with reference to the nominal operating frequency of the antenna (100), a predefined electrical length (d) measured between said first and second ends (5b, 5c) which is comprised between one fifth of a wave and three quarters of a wave, said supply circuit (5) being configured so that the signal fed in input into the first radiant element (1) is out of phase in time with respect to the signal fed in input into the second radiant element (2) by a first value comprised between thirty and one hundred and twenty sexagesimal degrees.
