In modern scenario, energy production without pollution at low cost is a critical task. This paper presents an efficient way to harvest energy from the unused received microwave signals. In communication systems, band stop filters are generally used to reject the unwanted signals to get a better signal to noise ratio. The rejected signals can be converted into useful DC power with the help of energy harvesting systems. The DC power generated thus can be utilized to maintain the power requirements of the receiver system or more attractively for the remotely placed wireless sensor systems where powering the system is crucial. For rejecting the signals an edge coupled metamaterial filter with cover type feed is proposed in this paper. With the help of a Vector Network Analyzer, the proposed filter prototypes are tested and the simulated results are validated
