What is the significance of effective length of patch?

An important factor that greatly affects a microstrip patch antenna's electrical performance is its effective length. This parameter affects the frequency at which the antenna radiates electromagnetic energy efficiently and is crucial in defining the resonant frequency of the antenna. The effective length plays a crucial role in attaining appropriate impedance matching since it affects the microstrip antenna's total impedance. Engineers can control and modify the form and orientation of the radiation pattern in accordance with design requirements since changes in the effective length also have a significant impact on the radiation pattern. Furthermore, the effective length is affected by the substrate material's dielectric characteristics and is intimately linked to the antenna's gain and bandwidth.
