DESIGN OF DUAL BAND ANTENNA FOR INDIAN REGIONAL NAVIGATIONAL SATELLITES

  JIGAR A SONI,  ANIL K SISODIA

In various applications, Dual-frequency/Dual-bands are desirable. Dual Band patch antennas may provide an alternative to large-bandwidth planar antennas, in applications in which large bandwidth is really needed for operating at two separate transmit- receive bands. Now a day’s Indian Regional Navigational Satellites System (IRNSS) uses L band For GPS Applications and for Surveillance Application we are using S band. Instead of using different receiving antenna for L band and S band, it is better to Design Dual band antenna which can serve both of these functions. Dual-frequency/Band Microstrip antennas have the advantages for doubling the system capacity of transmission and reception. For the proposed antenna two resonant frequencies are obtained in L band and S band which are 1.5GHz and 2.5 GHz respectively. The design and simulation of the proposed antenna is carried out using ADS (Advanced Design System) software. An extensive analysis of the return loss, Radiation pattern, gain, VSWR of the proposed antenna is done.
