A slot antenna module for switchable radiation patterns

In this letter, a microstrip antenna module with switchable radiation patterns has been designed, fabricated, and measured. The antenna module includes a power divider, a switch module, and a two-element Z-like slot antenna array. The wideband Wilkinson power divider is integrated with the dual-band single-port-single-through (SPST) switch module to provide two individual signal paths for the inputs of the two-element antenna array. By changing the bias voltages of the field effect transistor (FET) devices, the radiation patterns of the antenna array are changed and switched.
