The conformal application does not take up additional space that the missile would have been cramped. In order to enhance the received signal, the flexible printed board 1 is placed under the missile hull, with the telemetry antenna patch 2 located directly under the missile hull.

A telemetering antenna patch 2 is arranged in the middle of a flexible printed board 1, a pair of data chain antenna patches 3 are arranged on two sides of the telemetering antenna patch 2, and the telemetering antenna patch 2 and the data chain antenna patches 3 are arranged along the circumference of a missile body. The pair of data-link antenna patches 3 are connected by a data-link antenna feed network 4 for receiving a transmit signal, wherein the pair of data-link antenna feed networks 4 are fed in phase.

To ensure proper operation of the data chain antenna, the distance between a pair of data chain antenna patches 3 is greater than or equal to one-half of its operating wavelength. Due to the fact that the flexible printed board 1 is attached to the cylindrical surface of the missile body in a conformal mode, the pair of data chain antenna patches 3 on the two sides of the telemetering antenna patch 2 are bent inwards, and the distance between the pair of data chain antenna patches 3 is reduced.

In order to avoid mutual interference between the telemetry antenna and the data chain antenna, a telemetry antenna feed point 5 on the telemetry antenna patch 2 is located at the center of the flexible printed board 1, a data chain antenna feed point 6 of the data chain antenna feed network 4 is located on one side of the flexible printed board 1, and the telemetry antenna feed point 5 and the data chain antenna feed point 6 keep the maximum isolation distance under the space limit which can be met by a missile.

According to the invention, the data link antenna and the telemetering antenna are integrally designed on the flexible printed board 1, the flexible printed board 1 is arranged in a conformal manner with the missile body, and under the premise of ensuring the antenna performance, the narrow space of the missile is not additionally occupied, so that the space occupation of the data link antenna and the telemetering antenna on the missile is saved, and the manufacturing cost of the antenna is reduced.
