PROJECT TITLE :

Electromagnetic band gap-dipole sub-array antennas creating an enhanced tilted beams for future base station

ABSTRACT:

A completely unique customised electromagnetic band gap (EBG)-dipole sub-array antenna with a tilted beam for future base-station applications is presented. An enhanced tilted beam for the bottom-station antenna is one in every of the safest ways to increase radio coverage space adhering to the strict power necessities. An array of 4 dipole-EBG elements is intended demonstrating the enhanced down-tilt beam. Each single element consists of dipole antenna mounted on a customised EBG ground plane created by connecting several unit cells of the EBG. The proposed array radiates a tilted beam in order to attain a high directivity at fastened down-tilt angle. The array antennas are simulated, fabricated and measured. The directivity of eleven dB is measured at the angle of 28° at three.5 GHz. This directivity is 1.9 dB more than the reference case that uses the broadside single part. Further, the EBG-dipole array that can be mechanically tilted is intended. The proposed array antenna exhibits acceptable impedance matching across the operational frequency band.
