This paper presents the synthesis and modelling of a planar antenna array based on patch antennas for use in wireless information and measurement systems. Current trends in the development of microstrip patch antennas have been analyzed, their design variants examined, and approaches to miniaturisation and principles for forming antenna arrays for wireless information and measurement systems discussed. A single patch antenna element for an operating frequency of 2.4 GHz was synthesized and modeled. Requirements for the planar antenna array of wireless information and measurement systems are formulated, and key constraints related to the operating frequency range, efficiency, dimensions, and electromagnetic compatibility with other system components are identified. A variant of a compact planar antenna array is proposed, and a three-dimensional model of the patch element and its feeding structure has been developed. Numerical analysis was performed using ANSYS Student 2025. This paper presents the results of the design and modelling of an 8×8 patch antenna array with coaxial feeders, designed to operate at a frequency of 2.4 GHz. A high gain of 22.44 dBi was achieved, and a narrow-beam radiation pattern with minimal side lobes was formed, ensuring efficient signal transmission. Studies have shown an operating bandwidth of approximately 33 MHz and stable performance within this band. Proper impedance matching has been confirmed (reflection losses less than -10 dB), indicating high power transmission efficiency.
