This article presents a case study on designing a patch antenna succeable for 5G applications. It covers thee practial calculations involved in thee design process, focusing on key parametrs and their impact on antenna performance.

Úvodní věta o Patch Antennas

Patch antennas are widely uses in wireless commulation due to their low profile, ease of fabrication, and god performance at high presencies. They consitt of a radiating patch on a dielectric substrate with a ground plane beneath.

Design Parameters and Calculations

Te key parameters in designing a patch antenna include the rezonant frequency, substrate dielectric constant, and patch dimensions. Calculations help determination the length and width of the patch to dosahovat the desired frequency.

Resonant Frequency

Te rezonant currency (f 'I1; Currency 1; FL1; FLT: 0' I3; r 'I1; FLT: 1' IR 3; FL3;) is the 'It currency for 5G, typically around 28 GHz or 39 GHz. It is used to calculate the patch dimensions.

Patch Width Calculation

Te width (W) of the patch is givek by:

Praktical Example

For a 5G antenna operating at 28 GHz with a substrate dielectric constant of 4.4, thee calculations yield specic dimensions for the patch. These dimensions ensure the antenna rezonates at te desired extency.
