“…In [8], three types of slotted antenna are presented to enhance the bandwidth; T-slotted for patch and feed line, couple a ring and L slots and dual symmetry L slots. In [9], the ground plane is truncated and the patch has round junction and two chamfers to get a bandwidth of (1.79 -28.02) GHz (175.98%).…”

“…Ground plane 300 mm International Journal of Antennas and Propagation than the proposed antenna in this work, it was observed that the peak gain of the proposed antenna is higher than the peak gain reported by the authors and the radiation efficiency is not reported. e antenna proposed in this work is comparatively compact than the antenna reported in [15,17,19,24,25] as shown in Table 3. Although the proposed antenna in [20] has a compact size nonetheless with a peak group delay and minimum radiation efficiency of 4 ns and 35% while in this work, a peak group delay and minimum radiation efficiency are 1.1 ns and 78%, respectively.…”

A new compact ultrawideband (UWB) bioinspired antenna is presented in this work. The proposed antenna consists of a vine leaf (Vitis vinifera) shape as the radiating patch, defected ground structure (DGS), and a vertical rectangular slot (VRS) on the ground plane. The vine leaf shape is realized from a circular patch (initiator) in this work. The proposed antenna is built on an FR4 substrate with a dielectric constant of 4.4, a loss tangent of 0.02, and a thickness of 1.5 mm. The total dimension of the proposed bioinspired antenna is 35 × 27.6 mm2. The proposed antenna has a fractional bandwidth of 115.43% (3.7 GHz–13.8 GHz) at 10 dB return loss, a radiation efficiency between 78% and 97%, a peak gain of 6.7 dB, and a stable radiation pattern. The contributions of this work to the existing literature are as follows: (i) the investigation of a vine leaf shape for UWB antenna application; (ii) the adaptation of the conventional monopole patch antenna design equation to determine the lower edge frequency (LEF) of an arbitrary shape monopole antenna; (iii) the presentation of a compact UWB antenna with high fractional bandwidth compared with recent works in the literature, and (iv) the use of FR4 substrate to achieve a peak radiation efficiency of 97% with a compact structure.

“…Printed antennas have considered being a good candidate for communication due to its low profile structure. Similarly, an ultra-wideband low profile antenna has proposed by R. A. Santos in [18]. This particularly designed antenna covered a very wide range of frequencies from 1.79GHz to 28 GHz.…”

Distributed sensor networks are becoming more and more widespread due to their substantial benefits to our daily lives. These sensors, in most cases, are distributed in nature and even may require mobility. This, in turn, implies omnidirectional collector units to collect the data from various sensors at arbitrary directions. This work summarizes the performance outcomes of various integrated wide-band antenna structures and solar power generation topologies to achieve equal gain in all directions. Purpose of the array in this instance is contrary to enhance the received signal levels in all directions. Low-cost solutions ranging from the planar helical printed circuit board (PCB) designs to vertical wire helical antennas were investigated. An optimum design structure for multiple ISM bands (868 MHz to 915 MHz) was proposed and characterized considering the cost, size, directional coverage and most significantly RF sensitivity and range of the overall design. The final water-resistant solarpowered wideband transceiver front-end has provided range improvement and omnidirectional radiation pattern. The system consists of a 190mm x 190mm low-cost FR4 substrate and a Wilkinson network to combine the power of 8 helical wire antennas sprinkled along with the solar cells. The self-contained, Sun-powered unit resulted in 4.5-dB sensitivity improvement in measurements.
