a wideband antenna for 3G 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 3G band from 1.92 to 2.5 GHz.
