In this paper, a compact H-shaped slot antenna is proposed. The antenna contains a H-shape slot which is fed through
microstrip line, and an open circuited stub is connected for proper impedance matching. A H-shaped slot is used for bandwidth
enhancement. The antenna is designed to radiate at 5.4 GHz with a bandwidth of 1.6 GHz. The antenna has an omni-directional
pattern across the frequency band. The gain of the antenna is 4.35 dBi at 5.4 GHz. Since, the proposed antenna satisfies all the
characteristics of energy harvesting systems, it can be used for energy harvesting systems, at 5.4 GHz 4G-LTE band. CST
microwave studio was used for designing the proposed antenna. An excellent agreement is achieved between simulated and
measured results.
