摘要： A surface-mountable antenna is mounted on a substrate at one surface of its dielectric substrate, and is supplied with an RF signal by a feeding part which is provided on the substrate. The dielectric substrate is provided with one feeding through hole and at least one auxiliary through hole in parallel with each other, while a radiating electrode is formed on the inner peripheral surface of the feeding through hole. Further, end electrodes are formed on a surface of the dielectric substrate around the feeding and auxiliary through holes respectively, while an auxiliary electrode is formed on the inner peripheral surface of the auxiliary through hole. Due to this structure, it is possible to provide an antenna which is surface-mountable, has a high gain and controllable directivity.

摘要： An antenna device includes a signal-band separating circuit that is interposed between a communication antenna and a ground portion that are disposed on a circuit board. The communication antenna is connected to a communication circuit by a signal line via a signal-band separating circuit. A telecast-receiving antenna is connected to a broadcast circuit by a signal line. The signal-band separating circuit transmits signals in a frequency band for communication between the communication antenna and the communication circuit, and transmits signals in a frequency band for telecasts between the communication antenna and the ground portion. The antenna length (electrical length) of the telecast-receiving antenna is extended by adding the antenna length of the communication antenna in addition to the antenna length of the ground portion, thereby improving the antenna gain during telecast reception.

摘要： A circularly polarized antenna apparatus includes a radiating electrode and a ground electrode which are provided on a dielectric substrate. A degeneracy-splitting elements is also provided on the substrate to cause two resonant currents split between degenerate modes to be excited in the radiating electrode. The radiating electrodes includes a primary radiating electrode on a principal surface of the substrate, and secondary radiating electrode on side surfaces of the substrate, thus increasing the area of the radiating electrode. Therefore, the conductor loss of the primary radiating electrode is reduced and the antenna gain is increased.

摘要： In a feeding radiation electrode of a surface mount antenna, a series inductance component such as a meander pattern is formed locally in a maximum resonance current part in a high-order mode (second-order mode) so as to locally form a series inductance component therein thereby making the maximum resonance current part have a greater electrical length per unit physical length than the other parts. This makes it possible to control the difference between the resonance frequency in a fundamental mode and the resonance frequency in the high-order mode over a large range. Furthermore, it is possible to vary the resonance frequency in the second-order mode independently of the resonance frequency in the fundamental mode by varying the number of lines or the line-to-line distance of the meander pattern thereby varying the value of the series inductance component. Thus, it is possible to easily and efficiently design a surface mount antenna having a frequency characteristic which satisfies requirements needed in multi-band applications without having to change the basic design.

摘要： A multi-band surface-mounted antenna is formed by disposing a feeding element and a non-feeding element with a distance therebetween on a dielectric base member. The feeding element is formed by extending a feeding radiation electrode from a feeding terminal. The non-feeding element is a branched element formed by branching and extending a first radiation electrode and a second radiation electrode of the non-feeding side from a ground terminal side. The single surface-mounted antenna includes the three radiation electrodes. Thus, the antenna can be easily adapted to multi-bands. In addition, the resonance waves of the three radiation electrodes can be controlled mutually independently. As a result, only a frequency band selected from a plurality of required frequency bands is brought into a multi-resonance state so that the frequency band can be broadened.

摘要： A circularly polarized antenna device in which a recess is formed in the bottom surface of a dielectric base, and in which a feeder circuit is formed on an area of the top surface of a feeder circuit board covered by the recess. A shield for the feeder circuit is provided inside the recess. A feeder electrode is formed on an outer peripheral side surface of the dielectric base so as to be separated from a radiation electrode. A feeder wiring pattern which connects the feeder circuit and the feeder electrode so that they are in electrical conduction is formed on the top surface of the feeder circuit board. Electrical power supplied to the feeder electrode from the feeder circuit through the feeder wiring pattern is transmitted to the radiation electrode by capacitive coupling. Since the feeder circuit and the shield are accommodated inside the recess of the dielectric base, it is possible to restrict the bulkiness of the circularly polarized antenna device, and, thus, to make it thin. The invention aims at making the circularly polarized antenna device thinner.
