Abstract :
In this letter, a wideband antenna for 3 G indoor repeater applications is proposed. A wide impedance bandwidth was achieved using a 3-dB attenuator and mutual coupling between main and parasitic patches. The fabricated antenna has a VSWR below 1.5, a gain over 3.9 dBi, and an isolation between transmitting and receiving antennas higher than 80 dB over the 3 G band from 1.92 to 2.5 GHz.
