Bibliographical note
Funding Information:The first project was a joint venture between BGU and Technion [1] supported by the Information Super-Highway in Space consortium associated with the Israeli Trade and Industry Ministry. This work involved the development of a fixed-beam, dual-frequency (Ku-band) circular array with dual circular polarization based on printed elements fed by a radial network. The radial line-feeding network was chosen to reduce the antenna losses encountered with a standard microstrip conformal network and is based on two stacked circular patches fed in tandem by a single pin, as shown in Figure 1(a). Circular polarization was achieved for each circular patch by introducing two indents in the patch. To reduce mutual coupling among the array’s elements through surface-waves coupling, the elements were truncated to a square 12 mm × 12 mm, as shown in Figure 1(b). The elements in the array are arranged in concentric circles and fed through pins embedded in the radial line. The radial line is fed through a probe at its center. A prototype of the array with eight rings and a diameter of 30 cm has been built [Figure 1(c)].
