CROSS-SHAPED ANTENNA ARRAY

摘要

SOLUTION: A cross-shaped antenna array 1 includes: a first linear array 10 of a first radiation element 20; a second linear array 11 of a second radiation element 21 disposed to be substantially vertical to the first linear array 10; a common radiation element 22 disposed at an intersection point 12 between the first linear array 10 and the second linear array 11; and feed ports 30, 31, 32, 33 for receiving a feed signal.EFFECT: An antenna beam with various polarization (such as vertical/horizontal linear polarization and circular polarization) can be generated.SELECTED DRAWING: Figure 1
