Design patch antenna

To get the design results of a patch antenna use the method design(freq, er, h) by passing your resonant frequency (Hz), dielectric constant and thickness of the cavity (m) values as arguments.

Example code:

import patch_antenna as pa

# resonant frequency in Hz
freq = 2.4 * 10 ** 9

# dielectric constant
er = 4.4

# thickness of the cavity in meter
h = 1.6 * 10 ** -3

result = pa.design(freq, er, h)

print(result)

Output:

{'frequency': 2400000000.0, 'patch_width': 0.0380099749575278, 'patch_length': 0.0294215930843705, 'feeder_width': 0.015203989983011122, 'feeder_length': 0.015449608708025277, 'inset_gap_width': 0.007601994991505561, 'inset_length': 0.010914409094654586, 'ground_length': 0.05447120179239577, 'ground_width': 0.06281396494053892, 'input_edge_impedance': 321.50075290241097}

Write as Gerber file

pa.write_gerber(freq, er, h, 'patch_design_2.4GHz_4.4_er_1.6_h.gbr')

This will write the design in gerber file format. (Currently it will support only for normal feed type).

Future:

• Generating gerber files for inset feed type too.
