In this paper, the interconnect performance of closely spaced microstrip lines with embedded patterned layers (EPL) are presented. The EPL is an added patterned layer of printed sub wavelength elements that is placed between the ground and signal layers of the microstrip. A comparison of the performance of the microstrips with various EPL geometries is conducted. A study of the pattern density and...
A new broadband slot antenna is developed, which is fed on the coplanar waveguide (CPW), which is fed that, when the relative permittivity is lower (epsivr=2.2) and the substrate is thinner (h=0.8mm). The relevant simulation and calculation are performed by using CST Microwave Studio. The return loss curves and the radiation patterns of this new antenna are given. The results of simulation show that...
Microstrip Antennas (MSAs) consist of a metallic radiating patch on one side of thin dielectric substrate and other side is ground plane. Most important advantages of MSAs are low profile, light weight and compatibility with integrated circuit technology. MSAs are used in mobile communication, satellite communication, radar, direct broadcasting, global positioning systems and remote sensing. The major...
In this paper, the design of a compact planar bandpass filter above a defected ground plane is presented. The filter is designed as a combination of microstrip resonators and exploits the properties of a planar electromagnetic bandgap (EBG) structure patterned unto the ground plane of the printed circuit board material to provide a very wide stopband of up to 5 times the fundamental frequency. The...
