A 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...

Computational Analysis of Annular Ring Slot Loaded Microstrip Antenna

This paper presents an investigation conducted on annular ring slot loaded microstrip antenna operating in triple band and it is found to exhibit frequency tunability with the slot angle. Return loss of the proposed antenna has been investigated as a function of slot angle ? with fixed coaxial feed location. It is found that the said parameter of antenna depends heavily on the slot angle ?. Res...

Compact Slow-Wave Branch-Line Coupler Using Crossing Bond Wires

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 betwee...

Analysis of a Gap-coupled Stacked Annular Ring Microstrip Antenna

A theoretical analysis of a gap-coupled stacked annular ring microstrip antenna with superstrate is performed in order to obtain wider bandwidth operation. The effects of air gap, superstrate thickness and feeding point location on the antenna performance are analyzed in TM11 mode using equivalent circuit concept. It is noted that the proposed antenna is very sensitive to the feeding point loca...

Compact Branch-line Coupler for Harmonic Suppression

This paper presents the modified design that can reject harmonic components in the branch-line coupler. After adding open stubs at the center of branch lines of the traditional design, their new network parameters can be found in order to maintain the conventional function at an operating frequency and suppress its harmonic terms chosen. Experimental results show the second and third harmonic s...
