The plane surface super wide band antenna which possesses the circuit which is unified

摘要

(57) Abstract The plane surface super wide band (UWB) antenna which offers the unification of the electronic circuit is disclosed. The antenna has the 1st balance element which is connected to the terminal in on the one hand end. The 2nd balance element is connected to the other terminal in the end of one side. The 2nd balance element in order the optional point of planes of symmetry and the like for the planes of symmetry which are distance to exist vis-a-vis all mirror points on the 1st and 2nd balance element, has the form which reflects the form of the 1st balance element. Each of the balance element is produced from material of abbreviation conductivity. The ground element of form of triangle is arranged with the 1st balance element and the 2nd balance element which possess the axis of symmetry of planes of symmetry in addition in order for base of triangle to face to the terminal, orientation is done. Therefore, each of the ground element and the balance element forms the gap of two taper conditions, these spread, as the taper section from the terminal extending is present in outer part direction, focus with apex of the ground element. Under this constitution, it is possible to accommodate the UWB electronic circuit whose sensitivity is high around the ground element loss and dispersion of the transmission circuit are removed with this, in addition the system wringing becomes smallest. The resistant loop which is connected between the 1st and 2nd balance element raises the frequency response low, improves VSWR. Low connected method of the element array which offers frequency which is stipulated by the margin array size which is rubbed from element size cutoff is disclosed.
