Energy can be conserved by reusing what has already been spent. Such type of energy is readily available in the electromagnetic form (ambient RF energy). Signals broadcasted from AM, FM, cellular base stations and millions of other wireless devices can be converted to DC power. However, the main roadblock in this field of research is the level of power that ambient radiation carries. High efficiency antennas and rectifier circuits are required to harvest a fair amount of energy that can be used by low power devices. This paper presents the design of a novel multiband fractal antenna and a rectifier circuit that can be used to harvest ambient RF energy.

Hybrid fractal multiband antenna is designed usingKoch and meander geometry and its characteristics are investigated. The proposed antenna helps to achieve multiband behavior due to its multiple resonance characteristics. It has planar structure, compact size and suitable for wireless applications. IFS approach has been used to obtain the hybrid structure using MATLAB and scripting method of HFSS. Perturbation of basic structure is done to achieve quad-band behavior. Proposed antenna resonates at four different frequencies including Bluetooth (2.12-2.95 GHz) , WLAN (4.82-5.95 GHz), 4.07 GHz and 7.3 GHz. It is a low cost antenna designed on easily available FR4 substrate. It exhibits nearly omnidirectional radiation pattern and VSWR ≤ 2 for all resonating frequencies.

“…MPA, which is also known as the printed antenna, is a simple patch antenna that consists of a radiated metal foil patch on the top, dielectric substrate and ground plane. It can be easily fabricated on a printed circuit board (PCB) (Yu et al, 2015;Kumar et al, 2012). The name "Fractals," which refers to irregular fragments, plays a pivotal role in designing compact and multiband antennas.…”

Purpose Antenna miniaturization, multiband operation and wider operational bandwidth are vital to achieve optimal design for modern wireless communication devices. Using fractal geometries is recognized as one of the most promising solutions to attain these characteristics. The purpose of this paper is to present a unique structure of patch antenna using hybrid fractal technique to enhance the performance characteristics for various wireless applications and to achieve better miniaturization. Design/methodology/approach In this paper, the authors propose a novel hybrid fractal antenna by combining Koch and Minkowski (K-M) fractal geometries. A microstrip patch antenna (MPA) operating at 1.8 GHz is incorporated with a novel K-M hybrid fractal geometry. The proposed fractal antenna is designed and simulated in CST Microwave studio and compared with existing Koch fractal geometry. The prototype for the third iteration of the K-M fractal antenna is then fabricated on FR-4 substrate and tested through vector network analyzer for operating band/voltage standing wave ratio. Findings The third iteration of the proposed K-M fractal geometry results in achieving a 20% size reduction as compared to an ordinary MPA for the same resonant frequency with impedance bandwidth of 16.25 MHz and a directional gain of 6.48 dB, respectively. The operating frequency of MPA also lowers down to 1.44 GHz. Originality/value Further testing for the radiation patterns in an anechoic chamber shows good agreement to those of simulated results.
