✦ Synopsis


laser (EXFO FLS2600). The transmitted optical power is measured with a powermeter (HP 81532A), working in the 800 -1700-nm range. Both the optical source and detector are connected to a computer by GPIB links. By varying the wavelength of the tunable source laser and measuring the transmitted power, we can plot the transmission response of the various gratings.

## Abstract In this paper, the advantages of using L‐shaped microstrip feed to excite a rectangular dielectric resonator antenna (DRA) by electromagnetic coupling are presented. This feeding technique enhances the bandwidth and gain of the antenna without affecting its size. The experimental result

## Abstract This paper presents a new wideband dielectric resonator (DR) antenna. To enhance the bandwidth, two layers of stacked resonators having the same rotational axis of symmetry are used. At the bottom layer, a smaller cylindrical DR is placed concentrically inside a large annular‐ring DR, w
