Simple Beam Switching Cylindrical Dielectric Resonator Antenna Using Helix
In this paper, a simple approach is presented toward switching the radiation beam of the Cylindrical Dielectric Resonator Antenna (CDRA) using helical wire in two directions for S-band applications. The antenna radiation pattern may be altered to focus energy in two specified directions by introducing helix while reducing gain in other undesirable directions without changing the antenna impedance bandwidth because of its structural symmetry. The investigation of the proposed beam switching CDRA is designed and simulated using electromagnetic simulation. The proposed antenna has an impedance bandwidth of 50.10% and a simulated bandwidth that ranges from 1.78 GHz to 2.97 GHz. The proposed antenna is capable to switch the beam in two directions at 2.4 GHz.
