Abstract :
An electrical long slot antenna of novel structure is proposed. Half wave slots are interconnected with a phase reversing section consisting of quarter wave slot stubs and crossover wires. These sections ensure that adjacent half wave sections of the slot radiator produce in-phase radiation. The resulting structure produces two main lobes (forward and backward) with minimal minor lobes. A shielding structure can modify the radiation pattern to provide one main lobe.
