✦ Synopsis


Recently, 2-D photonic bandgap reflectors in microstrip technology ha¨e been proposed. Finite-element 3-D electromagnetic simulation shows negligible ¨alues of the fields outside the central row of the periodic pattern. This suggests the use of 1-D patterns to reduce the trans¨ersal size of the reflectors. Simulations and measurements ha¨e been realized, gi¨ing ¨ery similar performance for both 1-D and 2-D structures.
