Case Four

Compact Crossed-Dipole (Turnstile) Antenna for Global Navigation Satellite System (GNSS) Applications

Problem Description

Design Challenges

The  design and implementation of the crossed-dipole antenna for GNSS applications [1] is very challenging due to the following reasons:

  • Very high performance requirements in terms of return loss and axial ratio.

  • Highly compact design for military gear.

  • Unconventional non-rectangular (egg-shaped) driven and passive elements.
