<p>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. <IMAGE></p> |
