Abstract: front page image
(EN) The present invention in one aspect relates to a circularly polarized antenna having a conductive ground layer, a conductive patch and a dielectric substrate formed between the conductive ground layer and the conductive patch. The conductive patch formed in a square shape with four equal sides and has four square slots with each formed in the central portion of each side, and two rectangular slots orthogonally formed in the central area of the square such that one rectangular slot is aligned with one diagonal of the square, the other rectangular slot is aligned with the other diagonal of the square, and the junction of the two rectangular slots is coincident with the geometrical center of the square.
(FR) La présente invention concerne, dans un de ses aspects, une antenne polarisée de façon circulaire qui comporte une couche de mise à la terre conductrice, une plaque conductrice et un substrat diélectrique constitué entre la couche de mise à la terre conductrice et la plaque conductrice. La plaque conductrice de forme carrée, aux quatre côtés égaux, possède quatre fentes carrées, chacune formée dans la partie centrale de chaque côté, et deux fentes rectangulaires, formées perpendiculairement dans la zone centrale du carré, de sorte qu'une fente rectangulaire soit alignée avec une diagonale du carré, que l'autre fente rectangulaire soit alignée avec l'autre diagonale du carré ; et que la jonction des deux fentes rectangulaires coïncide avec le centre géométrique du carré.
