“…and an effective antenna area of = 1 2 , results in a theoretically estimated spatial power density of = 0.3 / 2 . The hypothesized antenna size is comparable to many of the state-of-the-art antenna designs published on UWB energy harvesting [17][18][19][20][21][22][23][24][25]. Moreover, it is clear that the theoretically expected value of = 0.3 / 2 is comparable to the values listed in Table 1 for RF EH techniques, which are based on much narrower frequency bands and much larger antenna dimensions, accordingly.…”

In this work, the feasibility of energy harvesting in the useful UWB band (i.e., 3.1-10.6 GHz) is analytically investigated. A typical UWB communications/EH chain in this band is modeled and analyzed, considering the spectral constraints imposed by the federal communications commission (FCC) to UWB signaling. Based on the developed model, accurate analytical expressions are derived for the average received powers of two common types of impulse radio UWB (IR-UWB) signaling waveforms. Numerical simulations on the system-level show excellent agreement with the obtained analytical expressions. Moreover, the DC power levels expected from spectrally constrained IR-UWB waveforms are extremely low (less than 0.3 microwatt) and, accordingly, provide useful guidelines for the design and development of ULP electronics applications in the sub-microwatt range.

This study proposes an ultra-wideband antenna for ambient radio frequency (RF) energy harvesting applications. The antenna is based on a co-planar waveguide (CPW) transmission line and incorporates a rectangular slot as an antenna harvester. The proposed antenna utilizes an evolutionary design process to achieve impedance matching of the 50 Ω CPW feeding line over the desired frequency bands. A parametric study investigates CPW elements and rectangular slot size. The harvester antenna is then connected to the primary rectifier circuit of the voltage doubler to examine the signal characteristics. The antenna covers the Industry, Science, and Medicine (ISM) Wi-Fi bands of 2.45 GHz and 5 GHz, achieving a realized gain of 3.641 dBi and 4.644 dBi at 2.45 GHz and 5 GHz, respectively. It exhibits a relatively broad frequency ranging from 2.16 GHz to 6.32 GHz, covering the ultra-wideband fractional bandwidth (FBW) of 105%.

“…It can be summarized from the contribution of this article and the comparison table that the geometry of the proposed antenna is novel; the structure of the proposed antenna is very thin; and it occupies less volume for implementation than the state-of-the-art mentioned in the table. The antenna offers maximum gain and efficiency as compared to other referred articles [11,17,19,20]. The designed antenna is suitable for Inter and Intra Vehicular (V2V) Communication, which has been justified through analysis of the antenna by placing the radiator at various positions on the vehicle.…”

“…A monopole antenna with double circular rings and dual operating bands was proposed by the authors in [19]. A monopole antenna with planar circular slots operating for ultra-wideband was proposed by the authors in [20]. It achieved a gain of 4.2 decibels, and the maximum radiation efficiency was 97%.…”

A multiple antenna placement system analysis for the improvement of efficiency and capacity for inter and intra vehicular communication is proposed in this article. Four antennas are placed in the four locations of the vehicular body which includes roof, side mirror, rear screen, and dashboard. The constituted antenna occupying the dimension of 40×38.5×0.2 mm 3 on flexible substrate material of photo paper and the bending analysis of the model as per the conformal nature on vehicular body is also analyzed and presented in this work. The received power from each receiving antenna response with respect to the transmitter has been analyzed. The channel capacity with respect to the antenna position for V2V communication is analyzed in different areas and in different environmental conditions.
