1WIRELESS SENSOR NETWORKSIntroduction In the field of electronics the concept of the antenna is an electronic device whose mainfunction is to convert the radio frequency into the alternating current and alternating current intoradio frequency. Antenna is divided into two categories: transmitting antenna which converts theAC current and convert into radio frequency and other one is receiving antennas which convertthe radio frequency into the AC current. The radio frequency and the AC currents are basicallythe information stored in form of data (Song, Nuaymi & Lagrange, 2016). The data is convertedinto the radio frequency so that it can be transferred to the large distances and in all directions. Ifthere is certain information and it has to be transferred to the larger distances and in all thedirection the radio waves are used. Radio waves are the basically an electromagnetic wavewhose wavelength in the electromagnetic spectrum is greater than infrared lights. They operatein the range of the frequencies 300 Giga Hertz to 3 Kilo Hertz with the correspondingwavelength of the range 1 millimeter to 100 kilometers (Abdulhamid, 2017). Thus thewavelength of the 100 km means that the information can be extended to 100 kilometers with thepowerful antenna thus the radio waves are crucial for communication. The first antenna was builtin the year 1888 by the scientist Heinrich Hertz. Today the application of the antenna is used invarious fields for which there are different types of the antenna. To design a antenna there arebasic components which has to be kept in the mind while desgining the antenna (Li et al., 2016)..They are:Antenna gain: the antenna gain determines how effective the antenna in its radial pattern.

Finally, the antenna has a higher broadcasting power and can accommodate a variety of channels. The cellular antenna with a large range is the superior alternative. And the benefit of adopting CDMA is that it is easily adaptable, but the downside is that as the number of CDMA users grows, the quality of the service declines and it becomes self-jammed.
