In a microwave module including a transmitting portion circuit and a receiving portion circuit, the transmitting portion circuit and the receiving portion circuit are respectively constructed by transmission lines of different kinds in which polarization planes are orthogonal to each other, and are constructed on the same surface of the same substrate. For example, one of the transmitting portion circuit and the receiving portion circuit is constructed by a microstrip line, and the other is constructed by a coplanar line. Further, one of the transmitting portion circuit and the receiving portion circuit is constructed by a microstrip line, and the other is constructed by a slot line. By this, there is obtained a microwave module in which mutual interference by an electromagnetic field between element circuits in the module can be suppressed, the circuits can be arranged close to each other without requiring a shielding member, and miniaturization of the module can be realized.
L'invention concerne un module d'émission-réception à hyperfréquence qui comprend un circuit d'émission et un circuit de réception. Le circuit d'émission et le circuit de réception sont constitués de différents types de lignes de transmission formant angle droit avec un plan de polarisation et disposés sur le même côté d'une carte. Par exemple, le circuit d'émission ou le circuit de réception est constitué d'un microruban et l'autre est constitué d'une ligne coplanaire ou d'une ligne microfente. Cela supprime l'interférence de l'un avec l'autre due au champ électromagnétique entre des circuits constitutifs dans le module. Les circuits sont arrangés serrés sans nécessité de blinder le matériau, et le module à hyperfréquence est miniaturisé.
