The dipole antenna performs long distance communication utilizing an electric field, and the loop antenna performs short distance communication utilizing a magnetic field. This composite antenna may be used as a wireless IC device in RFID systems.

  • Patent number: 8159412
    Abstract: Provided is an isolation antenna for a repeater which can acquire high isolation by using loop and dipole antennas, which are positioned in opposite directions to each other based on a shielding means, in a unidirectional repeater generally used in broadcasting or wireless communications even though transmitting antenna/receiving antennas having a co-channel are set up closely to each other. The transmitting/receiving isolation antenna includes: a shielding means including an electric conductor; a first antenna of a dipole antenna type in one side of the shielding means; and a second antenna of a loop antenna type in an opposite side of the shielding means where the first antenna is positioned.

  • Publication number: 20120001814
    Abstract: A radio frequency identification (RFID) antenna exhibiting a multiple resonance is disclosed. In one exemplary embodiment, a dipole antenna and a loop antenna are disposed upon a substrate and have dimensions and orientation to exhibit the multiple resonance. The dipole antenna may exhibit a first dipole section having a first length and second dipole section having a second length. The loop antenna may be disposed in a region of the dipole antenna. The ratio of the perimeter of the loop antenna to the sum of the lengths of the dipole sections may be selected to exhibit the multiple resonance.

  • Patent number: 8027636
    Abstract: Wireless repeaters comprising antennae having high electrical isolation are presented. Multi-band antennae are placed on opposing sides of a conductive ground plane to achieve high electrical isolation, preferably higher than 30 dB. The antennae are preferably placed at a distanced from the ground plane that is less than 0.5 wavelengths of a frequency associated with frequency bands to which the antennae are responsive. The presented antennae system reduces the minimum amount of isolation required for stable operation.
