نویسندگان
چکیده
This paper proposes a compact and miniaturized branch-line coupler using a crossing bond wire structured slow-wave branch line (CBWSWB). The proposed coupler achieves a size reduction of 82% compared with a conventional implementation. Measured S11, S21, S31 and S41 of the proposed coupler are better than −24, −3.7, −3.7 and −28 dB at 3GHz, respectively. Furthermore, the phase difference between through and coupling ports of the coupler is within 1◦.

Realization of a Compact Branch-line Cou- Pler Using Quasi-fractal Loaded Coupled Transmission-lines
An extremely compact branch-line coupler operating at 900MHz is presented without the use of via-holes, multilayered technique, or air-bridged. The technique presented here uses the concept of fractals to load a coupled transmission-line in order to realize a compact quarter-wavelength transmission-line, which forms the couplers arms. It is shown that the proposed branch-line coupler’s performa...
متن کاملMiniaturisation of a 2-Bits Reflection Phase Shifter for Phased Array Antenna based on Experimental Realisation
In this paper, a controllable reflection type Phase Shifter (PS) is designed, simulated and implemented. The structure of the 2-bits PS consists of branch line coupler, delay lines and six GaAs FET switches controlled in pair. The phase shifting is achieved by turning ON one pair of switches. The circuit design is fabricated using FR4 substrate with dielectric constant equal to 4.7. The size of...
متن کاملA Novel Circularly polarized dielectric resonator antenna with Branch-Line Coupler and Log-Periodic Balun
A new shaped circularly polarized dielectric resonator antenna (CP DRA) is studied with branch-line coupler and log-periodic balun for the GPS application. Since the coupler and balun are located under the DRA, it does not increase the footprint of the antenna, as a result the system is very compact. Two configurations are considered in this paper. In the first configuration, an external 50Ω lo...
