Review of Scientific Instruments, 1970
A simple and inexpensive microstrip transmission line of adjustable length is described. The device, although physically considerably smaller, is electrically similar to the usual coaxial line stretcher and can be fabricated easily from standard printed circuit or microstrip boards.

Microwave and Optical Technology Letters, 2005
A novel photonic bandgap (PBG) microstrip line is proposed for 50Ω conventional microstrip line. The proposed structure is fabricated with a periodic rectangle etched on the edge of the conductor line, and a flat and low-rippled passband is obtained.

IEEE Transactions on Microwave Theory and Techniques, 1980
This article summarizes state-of-the-art information on losses of single and coupled microstrip lines. Conductor loss, substrate loss (for pure dielectric or magnetic materials), and radiation loss are considered along with the effect of dispersion. Finally, a rough comparison is made between the losses of microstrip and that of several other types of ...

Characteristics of microstrip transmission lines
Journal of Electronics (China), 1990An efficient hybrid field solution to microstrip transmission lines is presented by using SLE and SLM modes in spectral domain. It by-passes the lengthy process of formulating the determinant equation for the unknown propagation constant. Compared with spectral domain admittance approach, this method is clear in both physical and mathematical senses ...

Microstrip lines on an indented cylinder
IEEE Antennas and Propagation Society International Symposium. 1998 Digest. Antennas: Gateways to the Global Network. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.98CH36194), 2002A combined mode-matching and moment method is proposed to study the transmission properties of single and coupled cylindrical microstrip lines with an indented ground. The results in the limiting cases match well with those in the literature. The effects on strip width, strip separation, indent (cavity) depth, indent (cavity) shape are analysed.

Analysis of a Cylindrical Microstrip Antenna Fed By a Microstrip Line
2006 International Conference on Mathematical Methods in Electromagnetic Theory, 2006A cylindrical microstrip antenna fed by a microstrip line is discussed. A problem has been solved by the moment method in the spatial domain using a relatively new representation of a spatial Green's function. For excitation a unit voltage source has been incorporated with the microstrip line.

Design of packaged microstrip line
2016 IEEE International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2016In this paper, a new-version microstrip line is proposed, named packaged microstrip line. It is comprised of three dielectric substrates. This novel microstrip line is no longer suffering from the issues of radiation losses, surface waves, or cavity resonances that exist in the standard microstrip line without or with a metallic shielding box.

Microstrip line with the PBG structures
APMC 2001. 2001 Asia-Pacific Microwave Conference (Cat. No.01TH8577), 2002The designed photonic bandgap (PBG) structure consists essentially of periodic perforations on a ground plane to provide effective and flexible control of electromagnetic waves along a specific direction. By controlling the position of the microstrip line, the designed PBG structures exhibit stop-band character. The optimal position of the 50/spl Omega/

Grooved suspended microstrip line
IEEE Antennas and Propagation Society International Symposium. 1998 Digest. Antennas: Gateways to the Global Network. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.98CH36194), 2002This paper presents a new type of a grooved suspended microstrip line configuration. The groove dimensions provide an extra degree of freedom in design to increase the impedance control capability of the line. The method of lines has been employed for this purpose. Finally, the dispersion characteristics of this new type of grooved suspended microstrip
