RT Conference Proceedings T1 Building Arrays with the Unidirectional-Radiating Complementary Strip-Slot A1 Hernández Escobar, Alberto A1 Abdo-Sánchez, María Elena A1 Camacho-Peñalosa, Carlos K1 Antenas AB An upgraded version of the complementary stripslot radiating element is reviewed. The original radiating elementconsists in a microstrip-fed slot in transmission configuration. In the proposed modification, the slot is backed by a cavity in orderto obtain unidirectional radiation. The presence of this cavity changes the behavior of the slot. A new equivalent circuit isused to propose a design methodology for broadband operation. Two array designs are simulated and implemented: a phasedarray and a log-periodic array. Promising experimental results verify the unidirectional radiation and the wide bandwidth ofthese antennas.
