A flattened antenna oscillator structure has a square frame with an opening in the middle of a lower side. Two vertical oscillator leads parallel to left and right sides are symmetrically arranged inside the frame. Lower ends of the vertical oscillator leads extend into the opening to form feeder contacts. The left and right sides of the frame have plural inward extending matching leads connected with the vertical oscillator leads. The pair of leads at the uppermost end is connected with the upper ends of the vertical oscillator leads. The layout of the antenna oscillator improves the anti-deformation ability of a whole antenna while combining different frequency bands and different frequencies, which improves the signal reception and receiving quality of the antenna oscillator. A variety of modulation structures are further arranged to maximize the receiving power of the antenna and reduce the loss caused by mutual interference between signals.
