DESIGN AND SIMULATION OF 1X4 PATCH ANTENNA ARRAY FOR RECTENNA

One of the methods to achieve wireless power reception is using electromagnetic radiation with rectenna. Rectenna is a combination of an antenna and rectifier. The antenna is used to receive RF/Microwave signal and the rectifier is used to convert the received RF/Microwave signal into DC signal. A 1X4 rectangular patch antenna array is proposed for receiving microwave signal for wireless power reception application. In this work, the antenna array is designed on a 0.254 mm thick Rogers 5880 substrate at 10 GHz frequency and the simulation is carried-out using ADS software. The corporate feed 1:4 power divider network is used to feed the signal from source to individual antenna element. The inter-element spacing of the array is 0.75λ.The antenna parameters such as return loss, gain, directivity, efficiency, polarization, half power beam width and 3D radiation pattern are obtained for single patch and 1X4 patch antenna array.
