Description

Fiberglass Radome is a structure that protects the antenna system from the external environment. It has good electromagnetic wave penetration characteristics in electrical performance, and can withstand external harsh environments in mechanical performance. Outdoor antennas are usually placed in the open air, and are directly affected by storms, ice, snow, sand, dust, and solar radiation in the natural world, resulting in reduced antenna accuracy, shortened service life and poor working reliability.

Fiberglass Radome Applications:

  • Aviation Radome
    It is generally a shell structure. Depending on the specific situation, a vertical incidence radome or a streamlined large incidence radome can be used. In order to meet the requirements of aerodynamics, the radome must be made into a streamlined structure. However, when the antenna is scanned in the radome, the incident angle changes greatly, making it difficult to obtain the best electrical performance of the radome. If it is not streamlined, it is usually designed as a radome with an incident angle of less than 30°, and its shape can be cylindrical, spherical or parabolic. Although the aerodynamic performance of this vertical incidence radome is worse, the electrical performance is better.
  • Ground radome
    Usually truncated spherical (about three-quarters of the ball), can be divided into two types of inflatable cover and rigid cover. Rigid radome is divided into shell structure radome and space skeleton radome.
    Inflatable radome
    The spherical membrane is fixed on an air-tight platform with a pressure plate around the cutout, and the circumference is tightened with a rope or fixed by other methods, and the inside is inflated. It has the advantages of thin and uniform cover wall, good electrical performance, and suitable for wide-band operation; the cover is soft and easy to fold, light in weight, small in size, and convenient to transport, store, and install. The disadvantage is that it needs to continuously inflate into the cover to maintain the shape and necessary rigidity of the cover. If the inflator fails, the cover will collapse and the antenna will be damaged. The United States has developed the largest inflatable cover with a diameter of 64.05 meters (210 feet) and is used as a radar antenna for the “Telstar” (Telstar).
  • Shell structure radome
    The cover wall is usually made into a curved shell, and the structural load is supported by the shell. Among them, the uniform single-wall shell structure is limited due to the consideration of operating wavelength and size; the foam plastic shell structure is due to the low dielectric constant and loss tangent of the material, and the thicker cover wall is allowed to be used electrically. Structural load requirements. The connection between the foam blocks can be glued to form a uniform overall shell, which has good electrical performance and is suitable for high-frequency and wide-band work; the sandwich shell structure is usually A-type sandwich structure. It consists of two symmetrical high-strength-density skins and a low-density core. Its advantage is that its strength-to-weight ratio and stiffness-to-weight ratio are large, and it is suitable for large ground radomes with a certain wavelength. But the disadvantage is that the working frequency band is narrow, the manufacturing is complicated, and the cost is high. When the A-type interlayer cannot meet the requirements, a multi-layer interlayer structure composed of odd-numbered layers can be used. The 44.4-meter-diameter sandwich radome successfully developed by China in 1972 adopted the A-type sandwich shell structure.
  • Space skeleton radome
    It is composed of a metal (or dielectric) spherical grid skeleton and a dielectric sheet (or film) covering it. The structural load is mainly borne by the grid skeleton. The design principle of the grid skeleton is to minimize the electrical shielding of the bar section while ensuring the mechanical performance. The strength and rigidity of metal are greater than that of dielectric materials, so metal skeletons are often used. Its advantages are that it is suitable for high-frequency and wide-band operation, easy to manufacture, relatively inexpensive, and suitable for large-scale ground antennas. The world’s largest metal space skeleton radome was built in 1964, with a diameter of 45.75 meters (150 feet), and is used for Haystack radar antennas in the United States.

Fiberglass Radome Features:

  • Strength – Stronger than steel shapes, pound-for-pound in lengthwise direction.
  • Corrosion Resistance – Resists most acids, caustics and salts.
  • Lightweight – Weighs 75% less than structural steel.
  • Low Maintenance – does not require constant de-rusting and repainting.
