Abstract

1454554 Aerials INTERNATIONAL STANDARD ELECTRIC CORP 17 Dec 1973 [18 Dec 1972] 58386/73 Heading H4A A scanning phased array system has N aerial elements but only M phase shifters, M being less than N. As shown in Fig. 3, for a linear array, input to a terminal 17 of a distribution network 16 is divided into M outputs which are fed via respective phase shifters to the M inputs of a subarray interconnecting network 15. The network 15 has N output terminals, which are connected to respective ones of the N aerial elements. As shown in Fig. 5, there is provided in said network 15 a power divider associated with each input, e.g. dividers 24, 26 for the inputs from the phase shifters 28, 29. Each divider has a direct feed to a main aerial element contained in a first group, e.g. the elements 19, 21, and has branch feeds for aerial elements which are at the sides of the main aerial elements, and which are contained in a second group. Coupler means are provided for combining the branch outputs from the power dividers associated with each pair of adjacent main elements for feeding those elements of the second group which are disposed between said pair of main elements. Thus, a coupler means 25 combine branch outputs from the power dividers 24, 26 to feed an element 20 which is between the elements 19, 21. Each main element together with the second group elements on each side of it forms a subarray, and it is shown that a limited scanning may be achieved without grating lobe formation. In another embodiment, a first group of main aerial elements 30 to 36, Fig. 7, are located at the centre and vertices of a hexagon and a second group of elements 37 to 48 are located one between each adjacent pair of main elements. Phase shifters feed power dividers associated with each main element. Each power divider has a direct output to its main element, and branch outputs to coupler means associated with each element of the second group adjacent said main element. Each coupler means therefore receives two inputs, which are combined to feed the associated one of the elements 37 to 48.
