Abstract In the proposed design, a collinear beam-steering array antenna is designed and analyzed. The proposed antenna has used corporate feeding to have improved characteristics of array antenna. A single band at 2.45 GHz is observed for single element antenna whereas multiband response is obtained in case of 1 4 array antenna. The antenna gain of 3.94 and 6.53 dB are obtained for single element and array antenna, respectively. Further beam-steering characteristics is observed and analyzed with variation in phase of feeding signal in case of proposed collinear array antenna. The compact size and beam-steering features make the antenna suitable for intelligent wireless communication. Keywords Collinear array antenna Antenna gain Beam steering

1 Introduction In the last few years in the systems development of communication, we need the reduced weight, optimized cost and much efficient antennas which are proficient of sustaining excellent functioning for frequencies of a broad range of spectrum. These technical trends had concentrated on the efforts to the design of a microstrip patch antenna. In wireless communications field microstrip antenna plays an important role which may be microstrip patch antenna, parabolic reflector antenna, slotted S. Pani (&) M.R.

antenna and the folded dipole antenna, etc. All of them are noble in corresponding to their own functioning, applications and properties. Antennas can be treated as the strength and spine which provide its support for the wireless communication and hence it played an important and crucial role in the technological developments. From microstrip patch antenna only dual characteristics, dual frequency operation, circular polarizations (LHCP, RHCP), agility of frequency, flexibility in the feedline, wide bandwidth, scanning and beam steering can be achieved easily. A linear array generally has more than one element and equally spaced with uniform excitations. In this we get continous shifts in the phase within the elements of the radiating waves in the electromagnetic spectrum from the plane of microstrip patch array antenna and also the reconfigurable antennas which in the combined form called as to be the multiport antenna. It uses intusion within the two orthogonal modes which causes interference. It could be prepared either to have the nulls direction under control [1, 2] or to emphasize the beam direction [3–5]. The reconfigurable antennas with the switches have many restrictions which can be overcomed by using these antennas in case when we are main
