چکیده
The modern mobile communication systems requires high gain, large bandwidth and minimal size antenna’s that are capable of providing better performance over a wide range of frequency spectrum.This paper presents the design of microstrip rectangular patch antenna with center frequency at 1.176GHz for IRNSS application. The array of four by one (1x4) patch array microstrip rectangular antenna with microstrip line feeding based on quarter wave impedance matching technique was designed and simulated using Advance design system(ADS) tool. The performance of the designed antenna was than compared with the single patch rectangle antenna in term of return loss, Voltage Standing Wave Ratio (VSWR), bandwidth, directivity, radiation pattern and gain. The array antenna on the substrate type FR-4 with dielectric constant of 4.6 and thickness of 1.6mm respectively.

In this paper, we investigate the benefits of a MULTI-GNSS receiver in an interference environment. The global satellite navigation systems GPS, GALILEO, GLONASS and COMPASSwill be considered. The regional navigation systems QZSS and IRNSS are not part of the investigation. We assume that a future Multi-GNSS receiver will use only CDMA signals. Therefore, the FDMA signals of the GLONASS system ...

With L band frequency allocations for satellite navigation getting more crowded, S band (2483.5-2500 MHz) is already allocated for navigation services, where Globalstar broadcasts downlink communications to user terminals. The Indian Regional Navigation Satellite System (IRNSS) is transmitting navigation signals and Galileo exploits some potential signals in S band. Also, several candidate S ba...
متن کاملRNSSs Positioning in the Asia-Oceania Region
Since the late 1990s, several Asian countries have developed plans to launch their own navigation satellite systems (NSSs). As a Global Navigation Satellite System (GNSS) is very expensive and complex – only the US and Russia have fully developed GNSSs so far, with Europe and China promising systems – a Regional Navigation Satellite System (RNSS) is a more feasible option. China launched its fi...
