Dual-band Circularly Polarized Antenna with Low Wide-angle Axial-ratio for Tri- Band Gps Applications
This paper presents the design of a dual-band microstrip antenna with low wide-angle axial-ratio. The antenna is designed for global positioning satellite operations at 1227MHz (L2), 1575 MHz (L1) and 1176 MHz (L5, available after 2007). This antenna has another advantage of a much wider band in both VSWR and 3 dB axial-ratio compared with single-fed GPS antennas. Details of the design, simulat...
متن کاملDual-Band Circularly Polarized Antenna with Differential Feeding
A dual-band circularly polarized antenna is presented in this paper. A rectangular patch antenna with gap-feeding structure is firstly designed, and 3-dB axial-ratio bandwidth from 2.35 to 2.48GHz is obtained. A parasitic square ring is placed on the rear of the rectangular patch as a band-notch unit operating around 2.4 GHz. Then an original wide circularly polarized band is split into two ban...
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...
متن کاملAsymmetrical-fed RHCP Wide-Band Slot Element for X-Band applications
An outstanding square slot element, for x-band wireless applications with asymmetric coplanar waveguide fed (CPW) is proposed. Various shapes of metallic strips are utilized as grounded stubs for providing Right Hand Circular Polarization (RHCP) functionality and wide-band properties. By adjusting the proposed stubs and hook-shaped radiator, length and positions, wider impedance band width is o...
