 This example considers the input impedance of a planar bowtie antenna in free space. The length and height of the bowtie are 100mm, giving a flare angle of :math:`90^\circ`.

-For the MoM, the bowtie antenna was created in MATLAB using the ``bowtieTriangular`` class:
+A Gaussian waveform with a centre frequency of 1.5GHz was used to excite the antenna, which was fed by a transmission line with a characteristic impedance of 50 Ohms.
+
+The module ``plot_antenna_params`` from the ``tools`` subpackage was used to calculate and plot the input impedance from the FDTD model.

+
+The bowtie antenna was created using the antenna toolbox in MATLAB, and the ``bowtieTriangular`` class.

-:numref:`antenna_bowtie_fs_zin_results` shows the input impedance (resistive and reactive) for the FDTD (gprMax) and MoM (MATLAB) models.
+:numref:`antenna_bowtie_fs_ant_params` shows the input impedance (resistive and reactive) for the FDTD (gprMax) and MoM (MATLAB) models. The frequency resolution for the FFT used in both models was :math:`\Delta f = 33.33~MHz`
