Abstract

The proposed Triple-band Compact Chip Antenna using Coupled Meander line and stacked meander Structure for Mobile RFID/PCS/WiBro. The proposed antenna is designed to operate at 900, 1800, and 2350 MHz, and is realized by parasitic coupled and stacked a meander line. Meander lines are using extend length of effective current path more than monopole and contribute miniaturization. The coupled meander line controls the excitations of the Mobile RFID and PCS, stacked meander line controls the excitation of the WiBro. The proposed antenna size is $11mm\times22.5mm\times1mm$. The antenna supports 900MHz, 1800MHz and 2350MHz operations simultaneously with bandwidths of 33MHz, 230MHz and 100MHz, respectively. The proposed antenna gains are result of simulation to be -0.8dBi, 3dBi and 3.8dBi, respectively.
