Final answer:
To design a microstrip patch antenna for a WLAN application at 2.45 GHz, optimize the dimensions of the ground plane, patch, feed, and matching cuts to achieve a resonance frequency of 2.8 GHz.
Step-by-step explanation:
To design a microstrip patch antenna for a practical WLAN application operating at 2.45 GHz, the important dimensions that need to be optimized include the length and width of the ground plane, patch, and feed, as well as the width and length of the two matching cuts on each side of the feed. The resonance frequency of the antenna needs to be 2.8 GHz. To achieve this, you can vary the dimensions mentioned above and use simulation tools or empirical formulas to determine the optimized values. For example, the length and width of the patch can be adjusted to achieve the desired resonance frequency.
