✦ Synopsis

structure device causes refractive-index perturbation in the radial direction of the fiber; hence, only asymmetrical cladding modes (LP11, LP12, LP13, . . .) will be coupled from the fundamental mode. To produce a broadband filter along the CϩL band, a grating device as long as 2.1 mm was used. The effective period of the device is 700 m.

The fiber used in the experiment has a core diameter of 8.2 m and an index difference of 0.36%. The spectrum of the device is measured using a tunable laser source with a bandwidth of 100 nm (1520 -1620 nm) and an optical-spectrum analyzer.

## Abstract The experimental implementation of a T‐shaped microstrip‐fed printed 8‐element slot‐array antenna is presented in this paper. Although the use of a high relative permittivity (ε~__r__~ = 4.3) substrate usually restricts the operation bandwidth, the radiation resistance also has a low va

## Abstract In this paper, we study a circular microstripline‐fed single‐layer single‐slot antenna. In this case, a modified circular microstrip feedline leads to good impedance matching in a wide dual band. The 10‐dB return loss impedance bandwidth is 50.8% for cellular (0.824–0.96 GHz) and GSM (0
