  • Antenna assembly
    Patent number: 7408523
    Abstract: An antenna assembly is disclosed which can minimize interference of antennas for communication services. The antenna assembly is suitable to minimize side-lobes and back-lobes interfering with each other in antennas used in a repeater for communication services. The antenna assembly includes a reflector having a structure capable of minimizing radiation patterns having front-to-back ratio (FTBR) characteristics, namely, back-lobes.

  • UNIFIED COMMUNICATION REPEATER
    Publication number: 20080081555
    Abstract: A unified communication repeater for wireless communication repeats signals between a network and communication terminals via a wireless line. The unified communication repeater precisely and stably prevents oscillation generation during bidirectional signal repeating, and minimizes radiation patterns serving as signal interference between a receiver antenna and a transmitter antenna for the bidirectional signal repeating.
