Phase-controlled linearly-polarised strip-line antenna array - has impedance transformers and phase shifters and commutating diode switches

摘要

The phase-controlled, linearly-polarised, strip-line antenna array has N dipole elemental radiators formed on an integrated circuit board using strip-line techniques and bearing a given spacial relationship to one another. The dipoles are linearly polarised and each is coupled to the supply line over a strip-line impedance transformer with phase shifter. The main supply line is divided into four branches and each branch has a diode switch. The four diode switches are normally non-conducting and act as the array's commutator.
