Abstract (en)
[origin: JPH02222203A] PURPOSE: To obtain a compact constitution by allowing two radiating elements to have the same symmetrical axis, and allowing signals radiated by the two elements to have the same radiation opening. CONSTITUTION: This device is constituted of two radiating elements having the same vertical axis, for example, two guides 10 and 11, and the first guide 10 is excited with a high frequency, and interrupted against a low frequency generated in the second guide 11. In the first guide 10, a radio wave is excited by an attached or printed antenna 12, for example, resonator, and the second guide 11 is excited with a low frequency by a plane annular antenna 13 electrically connected (for example, welded) to the first waveguide 10. Then, only a basic mode is added to the radiation of the opening of the second waveguide 11 in each frequency band. Thus, the device can be made compact.
