Abstract :
The spectrum below 10 GHz frequency will likely be congested and the spreading of millimeter wave technology in different emerging wireless applications as well as associated increase in energy consumption will be witnessed in the near future. Array antenna technology with higher beam efficiency (BE) and lower side lobe level (SLL) is required in order to increase the coverage area of wireless communication, transmission bit rate and at the same time decrease the energy consumption and interference. It is possible to achieve higher BE and lower SLL of array antenna by implementing different power distributions for different array elements. A new and technically better method of beam forming by implementing the concept of Staircase Power Distribution (SPD) of antenna elements has been investigated and compared with other edge tapering methods for 60 GHz signal. It is found that the Maximum Side Lobe Level (MSLL) is the lowest in SPD among the compared methods and the BE is also equivalent to those of other edge tapering methods. Fabrication of antenna elements with SPD technology is also easier since the number of different power distribution in SPD is least and stepwise uniform. The use of antenna elements in SPD in terms of power distribution is also the best among the compared edge tapering methods.
