A compact munition antenna system that includes a curvilinear transmit antenna on a top and bottom of a ring-shaped substrate, and a curvilinear receive antenna on the top and bottom of the substrate. The transmit antenna and receive antenna are positioned opposite one another on the substrate, and are separated by a pair of isolation barriers to reduce coupling of the two antennas. The munition antenna system may be mounted on a metal cylindrical portion of a guidance system in a nose section of the munition, using a vertical convex surface of the cylindrical portion and a horizontal surface of the munition as a reflector for improving antenna performance.

An antenna structure and an electronic apparatus are provided. The antenna structure includes a substrate, a first radiation part, and a second radiation part. The substrate has a first surface and a second surface opposite to each other. The first radiation part is disposed on the first surface. The first radiation part is an absorber material. The second radiation part is disposed on the second surface. The second radiation part is coupled to a feeding part. There is a distance between the second radiation part and the first radiation part, so as to excite a first resonance mode through the coupling of the second radiation part to the first radiation part. Accordingly, the specific absorption rate (SAR) value of the electromagnetic wave is reduced.
