In this comprehensive guide, we walk through the engineering workflow for designing a Rectangular Microstrip Patch Antenna.
Using a target frequency of 2.4 GHz and common FR-4 substrate parameters, we demonstrate how to translate electromagnetic theory into physical dimensions.
We cover the complete "Big Four" calculation steps:
Width (W): Optimizing for radiation efficiency.
Effective Permittivity (epsilon_{reff}): Accounting for fringing fields in air.
Length (L): Calculating the resonant dimension
Inset Feed (y_0): Using the cos^2 model to achieve a perfect 50 Ohm impedance match.

Whether you are preparing for an RF engineering exam or building a custom WiFi antenna, this video provides the mathematical foundation and practical tips needed for success.
