Aiming to the problems that excessive reduction of airborne telemetry antenna’s size will cause a sharp deterioration of the antenna’s bandwidth and gain, this paper proposed that using a high-impedance surface in the airborne telemetry antenna. As the size and bandwidth of the high-impedance surface is far from being able to meet the application requirements, this paper designed a new high-impedance surface which can be applied to the telemetry transmitter antenna, and reduced the profile size of the telemetry antenna and increased the gain of the antenna at the same time. In addition, based on the equivalent circuit model, we have resolved the contradictory situation of small size and wide band gap in the high-impedance surface design. The results show that the low profile, high gain and wide bandwidth of the telemetry antenna can be achieved by using the new high-impedance surface. The antenna structure and design ideas presented in this paper can significantly improve the performance of airborne telemetry antenna.
