摘要： In a coaxial connector, signal lines are switched over by mounting and dismounting a probe having a central contact, and fixed yoke terminals, a movable terminal, and a permanent magnet constitute a magnetic circuit. When the probe is dismounted, the contact portions are connected by the magnetic force of the permanent magnet. When the probe is mounted, the contact portions are disconnected against the magnetic force such that the central contact pushes a protrusion portion of the movable terminal.

摘要： A signal reception circuit includes a main antenna which receives signals in at least two predetermined reception frequency bands. A sub-antenna receives a signal in one of the reception frequency bands of the main antenna. A filter for interrupting a signal in the same frequency band as the reception frequency band of the sub-antenna is provided on a transmission line of a reception signal of the main antenna. A filter reflection signal in the same frequency band as the reception frequency band of the sub-antenna is induced in the sub-antenna, due to the antenna coupling thereof. The phase of the filter reflection signal is adjusted by a phase shifter between the main antenna and the filter, so that the induced signal of the sub-antenna is in phase with the reception signal of the sub-antenna. As a result, the level of the composed signal of the induced signal and the reception signal and is to be transmitted from the sub-antenna to a signal processing unit is greatly improved.

摘要： A surface mount antenna includes a substrate and a radiation electrode (having a predetermined resonance frequency) disposed on the substrate. An electrode is formed to cover four continuously connected surfaces including the front surface, the front end surface, the rear surface and the rear end surface of each substrate. Then, a dicer is used to cut a slit on the radiation electrode formed on the surface of the dielectric substrate. Here, the slit is arranged in a direction intersecting a direction &agr; connecting the two end surfaces. Subsequently, the dielectric substrate is cut into a plurality of portions along the direction &agr;, thus producing a plurality of surface mount antennas each including a substantially rectangular substrate and a radiation electrode formed essentially surrounding an outer circumference of the substrate.

A feed line is connected between a first feed point and a predetermined position between the first end and the second end of the first radiating element. The second radiating element has a first end that is a second feed point, a second end that is connected to the ground point, and resonates in a substantially ½ wavelength mode in a second communication frequency band. A distance from the ground point to the second feed point is longer than a distance from the ground point to the first feed point.

摘要： A circularly polarized microstrip antenna includes a dielectric substrate having only an emitting electrode for generating circularly polarized waves on a front surface of the dielectric substrate and a coplanar signal line for feeding the emitting electrode and a ground electrode on a back surface of the dielectric substrate. The ground electrode covers the entire area of the back surface of the dielectric substrate excluding a region in which the signal line is provided. The signal line extends from an edge of the back surface of the dielectric substrate to an intermediate position between the edge of the back surface of the dielectric substrate and a center position O of the emitting electrode on the back surface of the dielectric substrate. Thus, a circularly polarized microstrip antenna whose circular polarization characteristic can be easily improved and whose manufacturing cost and size can be easily reduced is provided.
