A foaming material is charged between a spherical lens and a radome, to form a foaming material layer, thereby to connect the both and support the spherical lens from the side of the radome, in order to provide an easily manufacturing and assembling method having excellent electrical properties, when providing an antenna capable of tracking a plurality of communication satellites and being installed in compact in a relatively small space. The foaming material layer is set at the same dielectric constant as that of the spherical lens or lower than that. Since the radome supports the spherical lens, any special supporting instrument is not necessary. Electrical deterioration occurs to the radome only, not to the supporting instrument. Generally, the radome is little affected by the electrical deterioration and the permeability of the electric waves is uniform, the permeable electric waves are hardly affected.

1. An antenna comprising:a spherical lens for concentrating electronic waves; a plurality of transmitting and receiving modules of moving independently at a substantially constant distance from a bottom hemispheric surface of said spherical lens, for forming electric waves toward the center of said spherical lens and its supporting/driving mechanism; and a radome for covering at least a top hemispheric surface that becomes an electric beam forming surface of said spherical lens; wherein a foaming material layer is interposed to integrate said spherical lens and said radome and said spherical lens is supported by said radome.
