A Compact Dual-band Planar Branch-line Coupler
A novel branch-line coupler which can operate at two frequencies is presented in this paper. The proposed planar topology, which is different from the conventional one, is analyzed and designed. The new coupler maintains not only compact but also dual-band characteristics. The length of the proposed stepped-impedance lines can be adjusted flexible according to the required operation frequency. ...
متن کاملDual-Band Branch Line Coupler using CRLH Transmission Lines
A branch-line coupler (BLC) working at two arbitrary frequencies using CRLH transmission lines (TLs) is presented. It is demonstrated that the two operating frequencies can be obtained by tuning the phase slope of the different line sections. A prototype is demonstrated using only microstrip technology.
متن کاملExtended Port Dual Band Planar Branch Line Coupler
Modern communication systems need various hybrids to enable digital data transmit via microwave bands. Thus several types of microwave quadrature hybrids have been reported for the realization of balanced circuits, matched attenuators, and phase shifter. The branch line coupler is one of the most popular hybrids for the convenience of design and implementation. But it offers limited bandwidth a...
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...
متن کاملDual-band Circularly Polarized Microstrip Antenna with Small Frequency Ratio
A compact single-feed dual-band circularly polarized (CP) microstrip antenna is evaluated numerically and experimentally. The dual-band performances with small frequency ratio (about 1 : 1.1) are achieved by a circular patch and a narrow annular-ring, which have small difference in radius. The CP characteristics are achieved by an unequal cross-slot embedded in the circular patch and two orthog...
