چکیده
A miniaturized, multi-band and circularly polarized (CP) antenna with high Front-to-Back-Ratio (FTBR) in the L1 band for global navigation satellite systems (GNSS) is developed this paper. The proposed CP consists of four dielectric substrates, each which forms a folded monopole parasitic inverted-L frequency bands (L1/L2/L5/L6). To improve FTBR, microstrip resonator situated multi-layer substrate beneath elements. FTBR improved by 4.2 dB when compared to without resonator. measured boresight gain more than 1.5 dBic over bands.

Dual-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...

This paper describes the design and testing of an aperture-coupled circularly polarized antenna for global positioning satellite (GPS) applications. The antenna operates at both the L1 and L2 frequencies of 1575 and 1227 MHz, which is required for differential GPS systems in order to provide maximum positioning accuracy. Electrical performance, lowprofile, and cost were equally important requir...

متن کاملDual-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...
