چکیده

Abstract

The  energy  harvesting  is  defined  as  using  energy that is available within the environment to increase the efficiency of  any  application.  Moreover,  this  method  is  recognized  as  a useful  way  to  break  down  the  limitation  of  battery  power  for wireless devices. In this paper, several antenna designs of energy harvesting are introduced. The improved results are summarized as a 2×2 patch array antenna realizes improved efficiency by 3.9 times  higher  than  the  single  patch  antenna.  The  antenna  has enhanced the  bandwidth of 22.5 MHz after load two slots on the patch. The solar cell antenna is allowing harvesting energy during  daylight.  A  couple  of  E-patches  antennas  have  increased  the  bandwidth  of  33%  and  the  directivity  up  to  20  dBi.  The received power can be improved by 1.2-1.4 times when using the dual  port  on  pixel  antenna.  Complementary  split  ring  resonator and  substrate  integrated  waveguide  are  utilized  cavity-backed feeding  on  a  fractal  patch  antenna  to  enhance  the  bandwidth around 5.1%. Moreover, adding a rectifier  circuit to  an  antenna converts the reserved RF-signal to DC power, and then duplicated  the  input  voltage  up  to  sum  the  total  number  of rectifier circuit stages. Therefore, the advantages and disadvantages  of  each  antenna  depend  on  the  technique  which  used in design.
