Abstract :
We have presented a dual spiral line loaded monopole antenna on a vertical ground plane. The antenna has a 152 MHz impedance bandwidth (820 ~ 972 MHz) for VSWR<2 at a central frequency of 896 MHz. The proposed antenna covers both the cellular and UHF RFID bands in Korea and is suitable as the internal antenna of a handheld transceiver unit because of its thin configuration, broad bandwidth, and good omnidirectional radiation characteristics.
