Patch antenna feed point calculator The PIFA (Planar Inverted F Antenna) is discussed. See how to design a patch antenna module PCB with a coaxial feed. How to use: 1- Enter the input parameters. Size: Patch length is typically λ/2 in the dielectric medium The centre of the patch as well as substrate is located at the origin coordinates of x-y plane, and the height of substrate at z-direction. I would like to remind you that in feeding a patch antenna, the location of the feed point determines the patch's input impedance at the resonance frequency. Nov 6, 2025 ยท The Antenna Calculator aims at delivering a comprehensive and practical tool to Antenna Engineering students and practitioners. A patch antenna (microstrip antenna) is a low-profile antenna printed on a circuit board. These can add a design parameter or degree of freedome that allows the performance to be tuned. The objective of this paper is to find the best feed point location, which achieves the highest performance for the designed antenna.
