In this paper a single fed microstrip patch rectenna for harvesting ambient radio frequency energy is presented. The antenna comprises of a clover shaped radiating patch operating at 2.4GHz ISM band. The rectifier circuit is placed in the same plane of radiating patch to minimize the overall antenna profile. The antenna is modelled and are fabricated on low loss roger dielectric substrate. Measured results show that the antenna achieves a peak gain of 7.19 dB in the operating ISM band with maximum RF conversion efficiency of 79%. The proposed antenna is suitable for wireless energy harvesting applications operating in ISM band.
