<p>Structure and inexpensive construction method for a flat microwave antenna of the type intended in particular for direct terrestrial reception of televised satellite transmissions. The spacing between the power supply circuit and the earth planes is maintained, for the most part, by the very structure of the radiating slots. This objective is attained by providing for at least certain of the said radiating slots (20a, 20b) to be thick slots each having a wall (31a, 31b) substantially vertical over at least part of the periphery of the slot. <IMAGE></p> |
