A novel linearly polarized water antenna inclined at 45 degrees with a high front-to-back ratio (FBR) is proposed. The broadside radiation pattern is realized by using a dipole to feed the structure. The dipole is placed near the ground surfaceto force the energy to the nearest field, reducing the energy loss caused by the distilled water. The results show that an impedance bandwidth from 823 to 873 MHz for |S₁₁| < -10 dB with again of approximately 7.73 dBi and a high radiation efficiency (better than 70% through the whole operating band)are obtained.
