Reconfigurable Bidirectional Wireless Power Transceiver

A compact planar inset-fed microstrip antenna applicable for 5G Wireless system at millimeter wave frequency (3-9 GHz) is described. The antenna parameters are optimized using the HFSS tool. Simulated return loss plot, far-field radiation pattern and polar plot gain is achieved at 28 GHz frequency. The simulation result met the 3GPP Release-15 operating in 2-9 GHz frequency band for 5G Wireless applications. The simulated results show a return loss of 12.4dB, gain of antenna is 9.72 dB and the voltage standing wave ratio VSWR < 2 indicating that the antenna has minimum reflection at this frequency.Reconfigurable Bidirectional Wireless Power Transceiver

INTRODUCTION – Reconfigurable Bidirectional Wireless Power Transceiver

  With the rapid proliferation of wireless communications systems, the limited electromagnetic spectrum has become more and more congested. On the other hand, it is widely recognized that the currently assigned bands are far from being fully utilized. Accordingly, the development of smart communication systems to efficiently use the spectrum of resources has attracted significant attention. Patch antennas are susceptible to working in multi-bands. This is performed by loading slots, slits, or shortening pins in the patch. When the slots are implanted at the maximum magnetic field location, the maximum effect of loading is gained. The slot antenna introduced in our work is varied from other usual antennas to coincide with the obligations of the prevalent 5G wireless communication system. Other work achieved by various researchers for designing 5G antennas, and arrays. In our work, we originate a novel principle of a compacted slotted microstrip antenna at 28/38 GHz which is appropriate for the coming 5G wireless communication. For super utilization of practicable handset space, a rectangular shape of two elements slotted microstrip antenna is presumed. Reconfigurable Bidirectional Wireless Power Transceiver


  • Port MIMO Antenna
  • Microstrip patch antenna capable of working in limited bands only
  • Array Antenna


  • Need for Complex Bias Networks to reach dual band utilization for dual-band allocation
  • Not capable of working in mm-wave applications.
  • Less reception due to high return loss.



In this paper, a novel integrated two-slotted patch antenna operated at 3 GHz to 10 GHz with DGS was introduced complying with the upcoming 5G mobile communication systems. Expected results such as S-parameters, antenna gain, and radiation efficiency were calculated and measured, and they can coincide with the obligations of 5G systems.

  • In the high-frequency band, the antenna gain will increase. Moreover, the radiated efficiency will decrease at the higher band. This may be occasioned by the reality that the directivity increases at higher frequencies.
  • In addition, better out-of-band rejection will be achieved in the proposed design.
