✦ Synopsis

In this paper, a novel 3-dB CPW multilayer slot-coupled directional coupler is presented and implemented. The coupler has two CPW lines coupled through a hexagonal slot etched on a common ground plane located between these lines. To increase the coupling between these CPW lines, a slot with sharp edges is used. The proposed directional coupler showed promising results, especially in terms of bandwidth (Ο³6 GHz). The simulated results are also compared with the measured data, and a good agreement is reported.

## Abstract In this article, a new compact defected ground structure (DGS) low pass filter (LPF) with wide rejection band, low insertion loss in the stopband, and sharp transition from passband to stopband is proposed__.__ The prototype LPF is composed of three repetitive DGS elements with open stu
