Abstract
Patch antenna is a low-profile antenna that has a number of advantages, low cost, light weight,easy to feed and their attractive radiation characteristics. For aWiMAX communication system, a microstrip patch antenna which operates at 2.76 GHz frequency band was presented in this work. The hybrid system solar cell antenna allows energy recovery as well as RF Transmission. A simulation process, withMATLAB, is used to determine the electrical power collected by the studied system as a photovoltaic cell. As a antenna, parameters such as gain, directivity, radiation pattern and radiated power were studied. Simulation results, showed a resonance frequency of the antenna at 2.76 GHz with an effective return loss of -18.64dB and a gain of 6.58dBi. Thereafter, an optical rectenna based on a solar cell antenna was proposed and studied.

In this work, we presented a Solar cell antenna dedicated to both Direct Current (DC) generation and RF transmission for WLAN/WiMAX application for the frequency of 2.76 GHz
We have increased the performance of the antenna by improving certain essential parameters of the antenna such as radiation pattern, gain and reflection coefficient
Summary
T HE advancement in the wireless communications is more improved in recent years compared to the past. Many microstrip antennas may be used in a variety of ways to improve the performance of communication systems. Due to their various advantages [1], patch antennas are popular in wireless communication. Solar cell and microstrip antenna are two separate devices, when their first use in satellite communication They compete for the available space on satellite which is generally limited in size. The optimal width Wf has been used for the design of the mesh patch or front face collection grid. Both optical waves, absorbed by the silicon (semiconductor), and the RF waves, collected by the mesh patch metal whose width of fingers Wf , will be optimized. When using a thin-film substrate we observe that the simulations become more complex and time consuming
