Abstract (en)
[origin: EP2432072A1] The balun has first and second transmission lines (31, 33) that are dimensioned such that equivalent electrical lengths of the lines and equivalent electrical lengths of line segments (36A, 36B) of third and fourth transmission lines (34, 35) are equal to quarter of wavelength of a predetermined frequency. The first and second lines are dimensioned to allow predetermined impedance transition between an asymmetrical connection point (31IN) and symmetrical connection points (36OUTA, 36OUTB). Another asymmetrical connection point is connected to a ground plane. An independent claim is also included for a network antenna device comprising radiating elements.
