Microstrip circularly polarized dual band Patch antenna design for NaVIC application

A dual band compact circularly polarized Patch antenna for dual band NaVIC (Navigation over Indian Constellation) receiver is presented. The concept of stacked patch antenna is implemented in this paper. The aim of this antenna is to receive 1176.45 MHz and 1575.42 MHz which are commonly known L1 and L5 respectively. These bands are used to receive IRNSS and GPS signals. The peak gain of 6.47 dBi for L1 frequency band and with angular beam width of 82
⁰
and 5.402dBi for L5 Band at angular width of 88.30 is observed.
