Abstract :
In this paper, an indoor repeater antenna is proposed. The necessary impedance bandwidth is obtained by utilizing the coupling between the main and parasitic patches. The isolation characteristic of proposed indoor repeater antenna between the transmitting and receiving antennas is improved by using a metamaterial absorber. The proposed indoor repeater antenna has a VSWR less than 1.5, a gain higher than 9 dBi, and an isolation between the transmitting and receiving antennas greater than 80 dB over the WCDMA band from 1.92 GHz to 2.17 GHz.
