Abstract: A wide-band flexible radome for a microwave antenna. The periphery of the radome is fixed on an enclosure disposed around the antenna and opposite to a reflecting surface of the antenna. The radome is formed by combining an outer polymer layer and a composite fiber textile structural layer having shielding and wave-absorbing wires mixed therein, and a tensioning element for connecting to a traction mechanism is arranged on a side of the radome facing the reflecting surface of the antenna. The traction mechanism is connected to the inner wall of the enclosure, and a tractive force capable of deforming the radome into a concave surface acts on the radome via the tensioning element. The radome of such a structure has good wave permeability, and it is not necessary to select a radome thickness according to the operating wavelength of the antenna. A radome having uniform thickness can achieve lower antenna insertion loss in a plurality of frequency bands and can meet the needs of multi-band microwave antennas. The radome achieves versatility over a wide frequency range, overcoming the disadvantage of conventional radomes made from materials such as ABS that exhibit performance differences in different frequency bands.
