Abstract:
|
A novel isofrequency-reconfigurable RF repeater operating at 4.5 GHz is presented. The repeater uses a total of
eight reconfigurable parasitic dipole elements to enhance and reconfigure the isolation level between the receiving (Rx) and the transmiting (Tx) antennas. The reconfiguration of the parasitic
dipoles is achieved using p-i-n diodes as microwave switches to change their electrical length. The parasitic dipoles are dynamically reconfigured into an optimum configuration state (to make them work as either director or reflector elements) to enhance and recover the perturbed isolation level when an obstacle is placed
near the repeater, while maintaining good impedance matching and pointing the maximum of the radiation pattern at the Rx port
toward a specific base station. |
