ANTENNA DEVICE GENERATING RECONFIGURABLE HIGH-ORDER MODE CONICAL BEAM

摘要

PURPOSE: A reconfiguring high order mode conical beam generating antenna device is provided to improve a transmission characteristic or a reception characteristic in an antenna. CONSTITUTION: A reconfiguring high order mode conical beam generating antenna device comprises a microstrip circular radiation body(5000), a power supply unit(6000), and a mode reconfiguring switching unit(6500). A microstrip radiator has a plurality of power supply points. The power supply unit outputs two signals including a phase difference and amplitude through one of the power supply lines. The mode reconfiguring switching unit is connected to a power sully unit through the power supply line and outputs the signals through switching operation according to external mode control data.
