Abstract
(EN) Provided is a circularly polarized antenna device that is inexpensive, and that can achieve downsizing and weight saving. This circularly polarized antenna device comprises a circuit board 10, a circularly polarized antenna 20, and a series power feed circuit 30. The circularly polarized antenna 20 includes four linearly polarized antenna elements 21 to 24 erected on the circuit board 10 and respectively connected to feeding points 11 to 14, and is configured to be able to receive circularly polarized waves. The series power feed circuit 30 for feeding power to each feeding point in series has transmission lines 31 to 33 and an impedance converter 34. The transmission lines and the impedance converter each have a characteristic impedance that is adjusted so that received signal amplitudes of the linearly polarized antenna elements are substantially equal, and the line length of each transmission line is configured so that phase differences between the linearly polarized antenna elements are substantially equal.
(FR) L'invention concerne un dispositif d'antenne à polarisation circulaire qui est peu coûteux, et qui permet d'obtenir une réduction de taille et une économie de poids. Ce dispositif d'antenne à polarisation circulaire comprend une carte de circuit imprimé 10, une antenne à polarisation circulaire 20 et un circuit d'alimentation en énergie en série 30. L'antenne à polarisation circulaire 20 comprend quatre éléments d'antenne à polarisation linéaire 21 à 24 montés sur la carte de circuit imprimé 10 et connectés respectivement à des points d'alimentation 11 à 14, et est conçu pour pouvoir recevoir des ondes à polarisation circulaire. Le circuit d'alimentation en énergie en série 30 pour alimenter en energie chaque point d'alimentation en série a des lignes de transmission 31 à 33 et un convertisseur d'impédance 34. Les lignes de transmission et le convertisseur d'impédance ont chacun une impédance caractéristique qui est réglée de telle sorte que les amplitudes de signal reçues des éléments d'antenne à polarisation linéaire sont sensiblement égales, et la longueur de ligne de chaque ligne de transmission est configurée de telle sorte que les différences de phase entre les éléments d'antenne à polarisation linéaire sont sensiblement égales.
