A four-port diplexer for high Tx/Rx isolation for integrated transceivers
A four-port diplexer consisting of two back-to-back three-port diplexers combined with a 180° phase shifter in one branch is presented. The technique achieves high Tx/Rx isolation with relatively low degree filters. Two experimental diplexers are demonstrated, one with equal Q resonators in all filters and the other with dissimilar Q factors, enabling miniaturization and cost reduction. Measure...
متن کاملCompact Dual-Band MIMO Antenna with High Port Isolation for WLAN Applications
A compact dual-band MIMO antenna with high port isolation for WLAN applications is proposed. The proposed antenna is basically composed of two monopoles and designed at 2.4/5.2 GHz. High port isolation is achieved by introducing a T-shaped junction on the top surface of the substrate and etching two slots on the ground. The measured bandwidth of the proposed antenna are 2.34– 2.55GHz and 5.13–5...
متن کاملCompact and High Isolation Microstrip Diplexer for Broadband and Wlan Applica- Tion
In this paper, a compact and high isolation microstrip diplexer is designed for broadband and wireless local area network (WLAN) application, simultaneously. The bandpass filter (BPF) for broadband channel is formed by three-coupled-line structure and two short stubs with different size loaded in 50 Ω feed lines, and the BPF for WLAN channel consists of two coupling quarter-wavelength resonator...
متن کاملThree-port versus four-port laparoscopic cholecystectomy.
BACKGROUND/AIMS Since the first successful laparoscopic cholecystectomy with the establishment of pneumoperitoneum in France by Mouret in 1987, it has become the golden standard for cholecystectomy. Generally techniques with four trocars have been used with surgeons but some of them prefer 3-trocar techniques. Our aim is to compare the clinical outcomes of three- and four-port techniques prospe...
متن کاملMicrostrip diplexer based on common dual-band filter
A novel microstrip diplexer with novel coupling structure is proposed in this letter. The proposed diplexer is designed with several stepped-impedance resonators. A dual-mode dual-band filter unit is used in this design to replace the conventional matching network, what is more, the dual-mode dual-band filter unit is resonance with other circuit resonator. The diplexer size can be reduced effic...
