Antenna transducers are those devices used to convert the radio frequency fields into alternating currents and vice versa. It consists of multiple components such as receiving antenna, transmitting antenna and a transducer. The radio frequency field is generated by the transmitting antenna that is transferred to the receiving antenna which converts these RF into AC with the help of a transducer. The growing trend of automation in flight control and increase in defence expenditure and R&D activities to develop ATR, capable of withstanding harsh conditions and providing long-range capabilities at low power consumption are some of the factors that have supported long-term expansion for Antenna, Transducer and Radome Market.
