Investigation of Binomial and Chebyshev Distribution on Dielectric Resonator Antenna Array

For wireless communication systems, the antenna is one of the most critical components for transmission as well as reception point of view. Good design of the antenna can relax system requirements and improve overall system performance. In addition to receiving or transmitting energy, an antenna in an advanced wireless system is usually required to optimize or accentuate the radiation energy in some directions and suppress it in others. Thus the antenna must also serve as a directional device in addition to a probing device. Many applications require radiation characteristics that may not be achievable by a single element. It may, however, be possible that an aggregate of radiating elements in an electrical and geometrical arrangement (an array) will result in the desired radiation characteristics [1]. The arrangement of the array may be such that the radiation from the elements adds up to give a radiation maximum in a particular direction or directions, minimum in others, or otherwise as desired. In this paper we concentrated on the electrical and geometrical properties of array elements that give a radiation maximum in a particular direction and minimum in others. We investigate the binomial and chebyshev distribution for linear and rectangular dielectric resonator antenna array.
