Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

An antenna array is a set of separate radiating or receiving elements arranged at fixed positions in space so that their individual waves combine, reinforcing in some directions and cancelling in others to form a directional beam. Yagi's 1928 Beam Transmission of Ultra Short Waves showed how arranging driven and parasitic elements as an array produces such a beam, and Balanis's later Antenna Theory gave the general treatment of the array factor and element spacing, including the phased array whose beam is steered by adjusting each element's feed. The referent is a physical arrangement of hardware whose geometry and timing shape a wave in space, not a body of summoned jurors, a block of indexed memory, or a surface of DNA probes.[1][2]
In computing an array is a block of memory holding a fixed sequence of elements of the same type, each reached directly by an integer index that gives its offset from the start, so any element can be read or written in constant time. Knuth's 1968 The Art of Computer Programming, Volume 1 gave the standard formal account of arrays and their address arithmetic, treating the array as a mapping from index positions to storage locations. The referent is an abstract and physical layout of data in a machine, measured in elements and bytes, and it is not a panel of jurors, an arrangement of antennas, or a grid of biological probes.[3]
A DNA microarray is a small solid surface, such as a glass slide, carrying thousands of known DNA fragments fixed in an ordered grid of spots, where each spot binds the matching molecules from a sample so that many genes can be measured at once. Schena, Shalon, Davis, and Brown's 1995 Quantitative Monitoring of Gene Expression Patterns with a Complementary DNA Microarray introduced this grid and used it to read the activity of many genes in parallel. The referent is a physical grid of molecular probes read by fluorescence and quantified per spot, and it bears no relation to a jury panel, an antenna array, or a memory array beyond the shared name.[4]
