Abstract : A multifrequency antenna for a missile is realized by an arrangement in which four microwave antennas are located under a narrow circumferential slot in the skin of the missile forming four separate antennas each with its own input connector. Each antenna consists of a probe fed annular quarter wavelength microwave cavity which radiate out of a top wall end slot. The cavity antennas are fed by a stripline distribution network directly under the antennas. Two L band antennas are positioned directly adjacent the inner surface of the missile skin and an S band antenna and a C band antenna are positioned beneath the L band antennas. A radome covers the circumferential slot. (Author)
