Advantages of Antenna Radome | disadvantages of Antenna Radome
This page covers advantages and disadvantages of Antenna Radome and its basics. It mentions benefits or advantages of Antenna Radome and drawbacks or disadvantages of Antenna Radome.
What is Antenna Radome?
The protective enclosure which is transparent to EM waves and used to protect antenna from harsh atmosphere is known as antenna radome. Following figures depict horn antenna radome and parabolic antenna radome.
Various radome materials are used as per application of usage such as PVC, ASA, FRP, syntactic foams, prepregs, Epoxy/Fiberglass, Acetal, ABS, Nylon 6/6, Polyetherimide, polystyrene, polycarbonate etc. Radome material should be anti-temperature, water proof, anti-aging and weather resistant.
Benefits or advantages of Antenna Radome
Following are the benefits or advantages of Antenna Radome:
➨It protects antenna system from impact of rain, wind, sand, snow and solar radiation.
➨It maintains antenna performance to be stable and reliable.
➨It reduces wear and corrosion of the antenna system. Hence extends life of the antenna.
➨It reduces weight of the mechanical structure and reduces inertia and improves natural frequency.
➨Test and maintance persons can work inside radome and hence they are protected from external environment.
➨In high speed aircraft, it solves problems caused due to high temperature and aerodynamic load on microwave antenna system.
Drawbacks or disadvantages of Antenna Radome
Following are the drawbacks or disadvantages of Antenna Radome:
➨It affects electrical performance of antenna at microwave frequencies.
➨It absorbs and reflects radiation wave in microwave or radar antenna. This causes transmission losses.
➨Radome causes distortion of antenna main lobe.
➨Overall construction cost of antenna system increases.
