Abstract

A directional coupler for radio frequency application, comprising: an input ( 110 ) for receiving a radio frequency input signal; a port ( 120 ) for delivering a radio frequency output signal; a first elongated conductor ( 150; 150:1 ), suspended in air between two ground planes, for connecting the input ( 110 ) with the port ( 120 ); the first conductor ( 150 ) comprising a sandwich structure with a first upper conductive strip ( 150 A), a first intermediate layer comprising a dielectric material and a first lower conductive strip ( 150 B); a second elongated conductor ( 200; 200:1 ), suspended in air between two ground planes, the second elongated conductor ( 200:1 ) comprising a sandwich structure with a second upper conductive strip ( 200:1 A), a second intermediate layer comprising a dielectric material and a second lower conductive strip ( 200:1 B); said first elongated conductor ( 150; 150:1 ) and said second elongated conductor ( 200; 200:1 ) being substantially parallel; said first upper and lower conductive strips and said second upper and lower conductive strips, respectively, having conductive interconnections ( 190, 210, 158 ).
