“…The design of all the circuitry was done using Computer Simulation Technology (CST) software and was optimized to operate optimally before fabrication [19][20][21][22][23][24][25]. All circuitry was tested on appropriate field conditions and hardware optimization was done to achieve desired results.…”

<span>Radio Frequency (RF) harvesting seems to be catching up as an alternate energy source whereby RF energy is scavenged from ambient sources and converted into renewable energy in terms of DC power. This converted DC power is then utilized to power up devices that require a low start up power in which eliminates the need for battery replacement. In this paper, a novel RF energy harvesting prototype is presented which consists of two microstrip patch antennas operating on GSM (900MHz) and WIFI (2.4GHz) & WiMAX (2.3GHz) frequency bands with a bandwidth of 220MHz and 10.11MHz respectively to harvest RF signals from ambience. Two matching networks are presented as well to ensure efficient power transfer to load. Rectifiers are designed to transform the RF signals to DC power. The converted DC signals are then combined and fed to a power management circuit which charges a 4.2V NiMh battery and drives a load at a regulated output of 3V.</span>

“…The Agilent HSMS-280 diodes are chosen to be used in RF to DC conversion circuit. These diodes have a very low forward voltage which suits best in this application [18][19][20]. The number of stages of voltage doubler was studied during simulation and 5-stage voltage doubler circuit is being implemented.…”

“…Micro-strip patch antenna is widely used for a wireless communication. It is very popular antenna in communication system, due to their low profile, low cost, easily implement and easily available [4], [6] and [10]. As we already know that micro-strip patch antenna is advantageous over conventional microwave antennas such as light weight, thin profile, dual frequency, and dual polarization, easy fabrication etc.…”

By using the concept of cutting slots and a hole, a micro-strip patch antenna is designed. In this antenna design we cut a "U" shape on a ground plane and via hole of radius 0.25 mm placed in between excited patch and ground plane. The antenna is designed on standard FR4 substrate with operating frequency 6 GHz. The simulation of proposed antenna is done on IE3D tool and measure characteristics of proposed antenna. We use the material with dielectric constant 4.4, height of material h=1.5mm, loss tangent 0.019 and the operating frequency of material for 6 GHz is introduced.

Rectangular microstrip patch antennas, although having many advantages, usually suffer from having narrow bandwidth. Changing the feed point, or adding slots to the patch or to the ground plane or the addition of resonant circuits to the structure are different methods that can be applied for enhancing the bandwidth. Slots are usually added for creating multiple band operations. In this work, design and implementation of a rectangular microstrip patch antenna with double L-Shaped slots is proposed for enhanced bandwidth. Design is done with simulation verification of the problem and testing of two prototype circuits. Simulated and measured responses for both of the antenna circuits are demonstrated. One circuit indicated about 600MHz bandwidth at 2.6GHz center frequency and the other one about 1GHz bandwith with center frequency being around 2.4GHz. 
