Most Significant Outcomes


  1. MIMO and Cognitive Radio for Sub-6 GHz 5G Applications: We have developed the compact antenna for 5G mobile communication where cognitive radio is going to play a huge role in the sub-6 GHz 5G network. We claimed a new 5G terminal antenna for the first time [IEEE Transactions on Antennas and Propagation, 2019], which integrates interweave and underlay communication schemes in Multi-Input-Multi-Output (MIMO) cognitive radio. This test was given in the range of 2.5 GHz-4.2 GHz. Our endless effort has resulted in a tunable smart 5G antenna with MIMO and cognitive radio [IEEE Antennas and Wireless Propagation Letters, 2019]. An eight-port MIMO interweave and a four-port MIMO underlay cognitive radio (CR) antenna system for sub-6 GHz 5G communications is another milestone in this direction. The final developed MIMO CR system has a sensing range, interweave communicating antenna tuning range, and underlay communicating antenna tuning range of 2.5-4.2 GHz, 2.5-4.2 GHz, and 2.15-3.3 GHz, respectively. [IEEE Transactions on Microwave Theory and Techniques, 2021].

  2. Circularly Polarized Compact Metamaterial Antenna: Compact antenna with circularly-polarization is another significant contribution of our research group. The inclusion of CP concept into a metamaterial based geometry revealing improved gain and miniaturization level is the novelest aspect of his innovation. We have successfully demonstrated a metamaterial CP antenna with axial-ratio bandwidth of 11.93% (at 3.5 GHz) with 5.62 dBi gain and a size reduction by 38.7% relative to a standard printed antenna [IEEE Antennas and Propagation Magazine, Jan. 2020].

  3. Dielectric Resonator Antenna (DRA): We have significantly contribution in this domain. Number of new antennas concept based on dielectric resonator (DR) are developed like multi-layer multi-permittivity for wideband applications, single feeding and differential feeding mechanisms to introduce the circular-polarization in DRs, modified DR structure with artificial magnetics conductor concept to realize the circular-polarization in DRs.
