Abstract
The rice husk is investigated as an absorber of RF signals produced by hybrid antennas in this research. The fabricated element plank of rice husk is placed between the feed line of the beam shaping antenna and radiating element of the beam steering antenna. Beam shaping antenna is activated by particular PIN diode switches to radiate with four well-developed multi-formities of beam shaping radiation patterns. The patterns contain the gain of 3.6 dB, 7.2 dB, 9.9 dB and 14.64 dB with HPBW of 135°, 85°, 35° and 25° respectively. It is proven that the signal reliability is paramount since the system could self-elucidate the mutual coupling effects with the aid of rice husk element plank. Through the deployment of green technology RF absorber, the antenna is potentially an effective way to decrease the number of drop outs, lost connections and provides larger coverage.
