Embodiment Construction
[0035] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0036] This embodiment provides a fractal array bionic ultra-broadband antenna, which specifically includes a substrate and a fractal array bionic radiation patch attached to the front of the substrate; the fractal array bionic radiation patch is composed of 25 photonic crystal batwing bionic An antenna array composed of small antennas arranged in a cross fractal array structure.
[0037] In this embodiment, the size of the small photonic crystal batwing bionic antenna is 2.0mm±0.01mm×2.0mm±0.01mm.
[0038] Such as figure 2 As shown, in this embodiment, the photonic crystal batwing bionic small antenna is composed of 9 pairs of parallel symmetrical oscillators, and the lengths of each pair of parallel symmetrical oscillators are 0.85mm±0.01mm, 0.70mm±0.01mm, 0.55mm± 0.01mm, 0.40mm±0.01mm, 0.25mm±0.01mm, 0.40mm±0.01mm, 0.55mm±0.01mm, 0.70mm±0.01mm, 0....
