Design and realization of a Dual Microstrip patch antenna for NavIC Applications

The Navigation with Indian Constellation (NavIC) is an initiative taken up by ISRO to develop and operationalize a regional navigation satellite system for Indian users. The NavIC constellation broadcasts the navigation signals in two services namely, the Standard Positioning Service (SPS) and Restricted Service (RS). Both these services are made available in two frequencies namely L5 (1176.45 MHz) and S (2492MHz). The NavIC space segment consists of a constellation of seven satellites placed in GEO/GSO orbits. The NavIC ground segment is responsible for the maintenance of the space segment and for enabling the navigation function. As part of the NavIC applications a dual frequency timing receiver using NavIC signals has been designed by ISTRAC and is in the process of realization through Indian industry. This paper addresses the design and the realization of a dual-band dual-patch (L5 and S) antenna solution for the In-house designed NavIC timing receiver.
