-            The dataset contains simulation results for antennas. Let's break down the key points from the data:
-
-            - **Frequency Range**: The antennas were tested across a frequency range from {frequency_range[0]} GHz to {frequency_range[1]} GHz.
-            - **Gain (dB)**: The antenna gain ranges from {gain_range[0]} dB to {gain_range[1]} dB. This indicates how much power the antenna is capable of directing in a particular direction.
-            - **Efficiency**: The efficiency of the antennas ranges from {efficiency_range[0]}% to {efficiency_range[1]}%. Higher efficiency is crucial for maximizing performance by minimizing energy losses.
