Rectangular Microstrip Patch Antenna Design for Artificial Intelligence Applications

Abstract

At 882 MHz, a simple rectangular microstrip patch antenna was implemented especially for industrial robotic applications. FR4 was the dielectric substrate material chosen with 4.4 as the dielectric constant. The projected antenna has been modeled using the finite element method (FME). Later, the antenna was fabricated and tested with a vector network analyzer. The antenna feed line (transmission line) at various distances from its right edge was investigated for good impedance matching in the resonant frequency band. Finally, to convert antenna load impedance (𝑧𝐿) to a 50𝛺 characteristics impedance, a quarter wavelength transformer was used. After determining congruence between FME-based and antenna-measured results, the radiation pattern of the proposed antenna was measured practically at the H and E- planes at 870MHz, 880MHz, and 890MHz.
