Conformal antennas have the characteristics of miniaturization,low profile,large antenna aperture,etc.,and are one of the key development trends of future antennas.The conformal antennas represented by pneumatic integrated antennas and ultra-wideband narrow beam antennas have become current research hotspots in the field of aircraft antennas.Current manufacturing processes of conformal antennas mainly include printing,transfer printing,laser processing,etc.,and large-area conformal manufacturing of antennas can be achieved by using appropriate processes.This review discusses the advantages of conformal antennas on different aircraft carriers.For example,printed low-profile airborne antennas can realize the requirement for aerodynamic-stealth integration of fighter aircraft,and can also meet the needs for small ultra-wideband antennas.Flexible antennas can be applied for inflatable and deployable antennas in satellites.The key technical problems of the current conformal antennas are explained,and future development of the conformal antennas in the aerospace field is also discussed.
