Optimized Circularly Polarized Bandwidth for Microstrip Antenna
In very high frequency performances such as spacecraft, satellite & missile applications where the size, weight, cost, performance, ease of installation & aerodynamic profile are constraints microstrip antennas (MA) are used to meet these requirements. In spite of limitations such as small bandwidth, low gain and low power handling capability, microstrip antenna offers good performance over oth...
متن کاملNovel Compact Circularly Polarized Square Microstrip Antenna
A novel compact circular-polarization (CP) operation of the square microstrip antenna with four slits and a pair of truncated corners is proposed and investigated. Experimental results show that the proposed compact CP design can have an antenna-size reduction of about 36% as compared to the conventional corner-truncated square microstrip antenna at a given operating frequency. Also, the requir...
متن کاملReconfigurable Circularly Polarized Compact Short Backfire Antenna
In this research paper, a slotted coaxial line fed cross dipole excitation structure for short backfire antenna is proposed and developed to achieve reconfigurable circular polarization. The cross dipole, which is fed by the slotted coaxial line, consists of two orthogonal dipoles. The dipoles are mounted on the outer conductor of the coaxial line. A unique technique is developed to generate re...
متن کاملOmnidirectional Circularly Polarized Antenna with High Gain in Wide Bandwidth
A novel omnidirectional circularly polarized (CP) slot array antenna with high gain is proposed, which is based on the coaxial cylinder structure, and the orthogonal slots radi‐ ated the circular polarization wave around the cylinder. Further, the improved dual cir‐ cularly polarized (CP) omnidirectional antenna based on slot array in coaxial cylinder structure is presented too, and two ports a...
متن کاملWide-Beamwidth Circularly Polarized Antenna and Its Application in a Sequential-Rotation Array with Enhanced Bandwidth
A wide-beamwidth circularly polarized (CP) asymmetric microstrip antenna is proposed by etching four novel unequal fan-shaped notches at the vertexes of the square radiator. A bandwidth of 1.5% and beamwidth of 156◦ are well achieved for an axial-ratio ≤ 3 dB (3-dB AR) at the central frequency of 1.575GHz. To widen the bandwidth, the asymmetric microstrip antenna is further expanded with the co...
