  • Patent number: 5805034
    Abstract: A microstrip patch filter in which a dielectric has a ground plane printed on one of its faces and a conductive arrangement printed on the other of said faces, the conductive arrangement includes a flat patch, input and output leads electromagnetically coupled to the flat patch, the flat patch or the dielectric substrate has a reactance-enhancing metallic constriction located along a portion of the patch. When the constriction is in the patch it forms a current-concentrating inductive constriction. When the constriction is in the dielectric substrate, it enhances the capacitance. In an embodiment, the patch has two mutually-transverse constrictions that divide the patch into four sub-patches cross-connected by current-concentrating inductive constriction.

  • Patent number: 5598168
    Abstract: The effectiveness of a microstrip conductor antenna, such as a patch antenna, is improved at any particular frequency by making the thickness of the conductor sufficiently small to reduce shielding and losses caused by the skin effect and make currents at the upper and lower surfaces couple with each other and make the conductor partially transparent to radiation. In one embodiment the thickness is between 0.5.delta. and 4.delta.. Preferably the thickness is between 1.delta. and 2.delta. where .delta. is equal to the distance at which current is reduced by 1/e., for example 1.5 to 3 micrometers at 2.5 gigahertz in copper. According to an embodiment, alternate layers of dielectrics and radiation transparent patches on a substrate enhance antenna operation.

  • Patent number: 5212491
    Abstract: An arrangement for increasing the level of radiated and received energy in a telescoping antenna while the antenna is in a collapsed position. The increase in energy is obtained through use of a sliding member which projects from the base of the antenna and contacts antenna matching circuitry for making changes to this circuitry when the antenna is collapsed. Initially tuned for resonating signals for transmission and reception with the antenna in an extended position, the antenna matching circuitry is retuned by a switching action provided by the sliding member for more effective resonating of these signals with the shorter length antenna. The switching action of the sliding member also activates gain control circuitry which increases the signal levels in both an associated transmitter and receiver when the antenna is in the collapsed position.
