In this paper, a rectangular dielectric resonator antenna (DRA) suitable for wideband applications is presented and a band notch of WLAN (5.15–5.75) GHz is proposed. The DRA is mainly composed of a 20 × 20 mm rectangular dielectric resonator, coated with metal on the top surface, and a circular monopole excitation patch with an air gap insert. A coaxial line feed is used to excite the circular, planar...
The physical characteristics of the materials perform an important factor in the design of the microwave filters. Several solutions have been proposed to improve the qualities of filtering. In this paper, we propose a new dual band-pass filter based on the coupling of a composite (CRLH) coplanar waveguide with complementary split ring resonators (CSRRs). The (CRLH) CPW is composed of two resonators,...
In this article, the authors present a new digital communication system combining a turbo code and modulation. Developed by a pragmatic approach. This combination based on the use of turbo-codes and the notion of binary encoding signal modulation considered minimizes the probability of bit error at the output of the channel (Gray coding). This system is not only relatively simple to implement, but...
