摘要： A multifrequency inverted F-type antenna which can receive muntifirequency band radio waves without the enlargement of its shape. A cut-out part (12b) is formed in an emission conductor (12) one end of which is connected to a short-circuit plate (13) planted in a ground conductor (11) and which has a feeding point (12a) to form on the emission conductor (12) a first emission conductor (12-1) and a second emission conductor (12-2) which resonate at respective frequency bands different from each other. By this construction the radio waves of two different frequency bands, i.e. a first frequency band determined by the shape of the first emission conductor (12-1) and a second frequency band determined by the shape of the second emission conductor (12-2), can be received.

摘要： A multifrequency antenna, which may be used as a built-in antenna of a small and thin radio communication terminal, such as a mobile telephone, is able to receive radio waves of multifrequency bands without enlarging the shape thereof. The antenna is structured using a main mode resonance frequency and a high-order mode resonance frequency of a single-frequency plane antenna with a short-circuit plate. Specifically, a radiator conductor plate in an optional shape is arranged on a ground plate, and the radiator conductor plate is connected to the ground plate via the short-circuit plate. Power is supplied to the radiator conductor plate from a power-feeding source via a feeder cable. In the radiator conductor plate, a cut portion for shifting the high-order mode resonance frequency to the location at a predetermined distance from the short-circuit plate is formed, and the high-order mode resonance frequency is shifted into a desired band by this cut portion. Consequently, the multifrequency antenna operates at least at two frequencies: the main mode resonance frequency, and at least one high-order mode resonance frequency shifted by the cut portion. Thus, a small and thin multifrequency antenna can be realized at a low cost without a concomitant increase in both the mounting area and the mounting volume of the multifrequency antenna.

摘要： A flexible substrate having a meandering antenna element and a matching circuit formed thereon is wound within an antenna cap and mounted on a terminal body. A rod-like antenna is arranged extensible within the flexible substrate. If the rod-like antenna is withdrawn, a linear antenna element is coupled by a capacitive coupling with the matching circuit formed on the flexible substrate. Also, if the rod-like antenna is returned into the terminal body, the capacitive coupling between the linear antenna element and the matching circuit is released, and the meandering antenna element is coupled by a capacitive coupling with the matching circuit on the flexible substrate.

摘要： A patch having a circular shape for instance is formed on the main surface of a substrate in the shape of, for example, an equilateral triangle. The center of the main surface of the patch is at a position different from the center of the substrate. A grounding conductor is disposed on the backside of the substrate. Power is supplied to the patch through, for example, a microstrip line, triplate line, coplanar waveguide, slot line or the like. An antenna configured as described above has the center of the patch at a position different from the center of the triangle substrate, so that beams can be tilted in a desired direction by a single patch and a single feeder circuit.

摘要： A microstrip antenna is disclosed which comprises a ground conductor plate and a patch opposed to the ground conductor plate with a particular distance, a transmission feed line and a reception feed line being disposed between the ground conductor plate and the patch. Signals are fed from these feed lines to the patch by electromagnetic coupling. The angle made by the extended lines of these feed lines is nearly 90.degree.. When four patches are disposed in a square arrangement, the transmission feed line feeds signals in directions of first lines which pass through the center point of each patch in such a way that the directions are line-symmetrical with respect to a horizontal line and a vertical line which pass through the center point of the square arrangement. On the other hand, the reception feed line feeds signals in the directions of second lines which pass through the center point of each patch and intersect with each first line at right angle. As a result, the mutual coupling between transmission and reception can be suppressed to a low level. In addition, when the transmission feed line is radiately connected from the center point of the square arrangement to each patch, the length thereof can be reduced, thereby decreasing the transmission loss.
