A NOVEL MINIATURIZED MICROSTRIP SIX-PORT JUNCTION

A New Six-port Junction Based on Multilayer Technology

A novel design of compact six-port circuit is proposed for millimeter-wave integrated system design. All the structure is based on the use of an elliptic coupler with certain geometrical characteristics. The prototype circuit occupies only 66.5 % of the size of the conventional six-port junction at the same frequency. To examine the performance of the proposed circuit, the six-port using multil...

A Miniaturized Triple-Mode Microstrip Bandpass Filter

A Novel miniaturized triple-mode microstrip bandpass filter (BPF) using space mapping (SM) technique is presented in this paper. Three operating frequencies at 1.9 GHz, 2.14 GHz and 2.45 GHz are excited that are used for CDMA, WCDMA and RFID applications, respectively. In the proposed design, Substrate manufactured from RT_DURRIOD_5880 with dielectric constant of 2.21 and height of 20 mil that ...

Miniaturized UWB Microstrip Antenna for Microwave Imaging

This article presents the design of a miniaturized microstrip antenna for microwave medical imaging applications. We propose a miniature rectangular printed antenna that meets the UWB characteristics in terms of bandwidth and reflection coefficient. This antenna is designed for a system to detect malignant tumors by microwave imaging. We use certain techniques of miniaturization and expansion o...

Symmetrical Six-port Waveguide Junction with Metallic Post and Dielectric Sleeve in Over-sized Cavity

The Least-Squares Boundary Residual Method is employed in the present paper to develop a computer model of the symmetrical six-port waveguide junction. The analytical formulation is difficult because of the insertion of a metallic post together with a dielectric sleeve into the over-sized cavity of the junction. Computational and experimental tests confirm that the resultant model is able to co...
