In this paper, the design of a 10 mW concurrent triband RF rectifier at 1050 , 2050 and 2600 MHz using the high impedance transmission line with two short stubs is presented. Experimental results show that the efficiency is achieved 59.2 % at 1050 MHz, 35.6 % at 2050 MHz and 52.2 % at 2600 MHz. Compared to the state-of-the-art of multi-band rectifiers, the proposed triband rectifier has the ability to harvest RF energy from the corresponding operating frequencies sources.
