“Design of a shielded antenna system for ground penetrating radar applications,” 2009 IEEE AP-S International Symposium and USNC/URSI National Radio Science Meeting, Charleston, South Carolina, USA, June 2009.
Abstract
A practical design guidance of a wide band shielded GPR antenna is discussed. The designed antenna is used in a GPR system working at 400 MHz center frequency. Measured data show that with properly designed shielding and absorbing materials, the bow-tie antenna with shield performs as desired. Besides antenna design, the key issues in a shielded GPR antenna design are the depth of the shield box and the absorbing material insertion.
