Design and Implementation of a Printed Circuit Model for a Wideband Circularly Polarized Bow-Tie Antenna
Abstract
:1. Introduction
- A design for a circularly polarized, wideband 2.44–7.62 GHz S- and C-Band antenna that does not require hybrid couplers or multiple feeds;
- Analytical solutions to the input admittance of the antenna that can be used to adapt the design without time-consuming full-wave simulations and optimization;
- An integrated matching network design to improve the bandwidth of the antenna;
- An equivalent circuit model of the proposed matching network that can expedite the design of similar matching networks prior to full-wave simulation.
