A coupling control capacitor element is connected between these two radiating patches and resonance control capacitor elements are connected between the radiating patches and the ground plate, respectively. Capacitance of the coupling control capacitor element is selected such that a current coupled from one of the two radiating patches to the other and a current supplied from the said one of the radiating patches to the other via the coupling control capacitor element are in opposite phase at the other one of the radiating patches.

Abstract: An antenna which is adapted to have multiple fundamental resonances includes an outer conductor electrically connected to a feed network and having a generally tubular portion opening through one end to define an internal cavity therein. The antenna also includes an interior conductor electrically connected at a first end to a portion of the outer conductor within the internal cavity. The interior conductor extends through the opening defined in the outer conductor to a second end to thereby define an extended conductor portion which extends beyond the outer conductor. The antenna also includes decoupling means for electrically decoupling the extended conductor portion of the interior conductor from the antenna for signals having frequencies within the upper frequency band. In one embodiment, the internal conductor portion has a predetermined electrical length equal to an odd multiple of a quarter wavelength of a signal having a frequency in the upper frequency band of the antenna. Thus, the extended conductor portion is effectively electrically decoupled from the antenna for signals having frequencies within the upper frequency band.

Abstract: A three-wave antenna for vehicles which includes a monopole antenna element which has an electrical length of approximately 1/4 of the wavelength in the FM broadcast band along with a double sleeve used to prevent current flow and with a second double sleeve used for phase adjustment that are installed coaxially with the antenna element. The positional relationships between the inner and outer cylinders of each one of the first and second double sleeves relative to the antenna element are respectively specified. In addition, an antenna attachment which has a capacitive reactance and is installed at the base of the antenna element so that it cancels the inductive reactance of the antenna and causes the impedance of the antenna to approach a prescribed value is employed together with a wave splitter which includes a high pass filter that has a double tuning function with respect to the inductive reactance and the capacitive reactance and a low pass filter that separates the AM/FM broadcast band signals from the telephone band.

Abstract: An antenna element including a loading coil is telescopically extendable and retractable from within a housing tube. A characteristic impedance of a transmission line from a lower end part of the antenna element to a cable is equal to one of a cable. A part of the loading coil is reinforced. A branching filter, which is operatively connected between the antenna and a communication device using a different frequency band, suppresses a mutual interference between signals for the communication device. An antenna circuit, which is operatively connected between the antenna or a branching filter and the communication device, converts an impedance of a lower part in a frequency band, and reduces a loss due to a capacitive antenna impedance.
