  • Publication number: 20150130683
    Abstract: An antenna is connected to a first end of a high-frequency transmission line, and a connector is connected to a second end of the high-frequency transmission line. A characteristic impedance of a microstrip line is higher than characteristic impedances of first and second strip lines, and a characteristic impedance of a coplanar line is higher than a characteristic impedance of the second strip line. Thus, at a certain frequency, a standing wave develops in which the position of the microstrip line and the position of the coplanar line are maximum voltage points and three-quarter-wavelength resonance is a fundamental wave mode. Thus, the cutoff frequency of the high-frequency transmission line is high, and an insertion loss of a signal is significantly reduced to be low over a wide band.

  • Patent number: 8772088
    Abstract: In a high frequency module, electronic components are mounted on a mounting surface of a collective substrate including a plurality of unit substrates that include a via conductor electrically conducted to a ground potential in a peripheral portion thereof, and the mounting surface and the electronic components are encapsulated with an encapsulation layer. The collective substrate is cut on the encapsulation layer side, thereby forming a half-cut groove penetrating through the encapsulation layer and extending halfway along the collective substrate in a thickness direction such that the via conductor is exposed only at a bottom surface of the half-cut groove. A conductive shield layer is formed to cover the encapsulation layer and is electrically conducted to the exposed via conductor. The collective substrate is then cut into individual unit substrates each including the conductive shield layer electrically conducted to the ground potential through the via conductor.

    Abstract: An antenna system is described which is comprised of an artificial magnetic conductor (AMC), an antenna element, and a feed network comprised of shielded feedlines whose outer conductor, or shield, is routed through the substrate of the AMC. The feedline outer conductor is connected to both the substantially continuous conductive surface and the array of capacitive patches forming the AMC. The shielded feedline suppresses the excitation of undesired TM modes within the AMC substrate, results in a stable return loss over a frequency range associated with the AMC's high surface impedance and surface wave bandgap.
