Abstract
This invention relates to utilizing a larger number of lower power transmit/receive modules in a phased antenna array in order to utilize cheaper and simpler transmit/receive modules whilst retaining comparable power per unit area as can be achieved through using conventional high powered transmit/receive modules. The advantage of this arrangement is that cheaper antenna arrays can be constructed without limiting the capability and/or performance of a system incorporating such an array when compared to a conventional solution.
Claims10
A high-power phased array antenna comprising:
- an array of radiating elements;
- and
- a low power communication module connected to each radiating element, and
- at least one combining element that receives an output of each low-power communication module and communicates with a processor of the array,
- wherein said radiating elements are spaced apart horizontally and vertically in the array by predetermined amounts D1 and D2, respectively, wherein D1 and D2 are directly proportional to each of a power requirement value of the array antenna and a power per unit area value for achieving the power requirement, and
- wherein a power density of said low-power communication modules is directly proportional to each of the power requirement of the array antenna and the spacing of said radiating elements, and indirectly proportional to a power value of each low power communication module.
