Most antennas' gains are measured with reference to an isotropic radiator and are rated in decibels with respect to an isotropic radiator (dBi).A Dual-band RFSR is created to develop a dual-band pattern reconfigurable corner reflector antenna.
The unit dBi indicates decibels with an isotropic radiator as the base comparison, and dBm indicates a base of 1 mW fed into 50 ohm impedance (common for wireless sensors).
Array theory shows that to avoid ripples in the pattern at the test area the elements must be closer to each other to approximate the pattern of an isotropic radiator.
