“…The proposed antenna is a modified version of a circular monopole, which means that the proposed radiating leaf is quasi‐circular; the fundamental operating frequency equation of the circular one can be applied to the proposed one for obtaining fundamental parameters. The design equation of the circular monopole in Figure 2A (Ant‐1) is given by References 28–31:

f_{L} = \frac{7.2}{l + r + p} GHz

where, l is the length of the monopole, r is the effective radius of an equivalent cylindrical monopole antenna and p is the probe length in cm and f L is the lower operation frequency of the antenna. If Equation () is written in term of the disk radius ( R ) and the probe length, lower resonance frequency is expressed as follows:

f_{L} = \frac{7.2}{(2.25 R + p)} GHz

According to this equation, the radius value is taken as 24 mm for the lower cut off frequency of the circular antenna (Ant‐1) to be 1.3 GHz.…”

In this article, both design and implementation of a novel Omni‐directional bioinspired Linden leaf‐shaped rectenna are reported. The antenna is designed for the energy harvesting purposes under the operation frequency range between 1.6 and 2.65 GHz with a second harmonic rejection property. At the rectifier stage, voltage doubler circuit is designed and implemented with the help of microstrip transmission lines, which are used for impedance matching procedure between the antenna and the rectifier for the optimum power transfer from the antenna to the load for the operation dual bands of universal mobile telecommunication service and WIFI. In the design, SMS7630Schottky diodes, high frequency capacitors and inductors are used as the main surface mount devices. The FR4 epoxy material is selected as a substrate material for both the antenna and the rectifier circuit due to its low cost and easy—production scheme. The maximum efficiency value realized at the dual band operation is 42% at the 0 dBm input power level. The output voltage value and the harvested power at this point are nearly 960 mV and 0.42 mW with an optimum load RL = 2.2 KOhm. The implemented system can be used efficiently for the RF energy harvesting applications for the proposed frequency bands.

“…The measured gain, G dBiL , is converted to G dBiC (gain of the circularly polarized antenna) by adding 3 dB to the values of G dBiL of Eq. (8) and is plotted. Another variation of G dBiC is by introducing a correction factor G cf , wherein the axial ratio (AR) of the antenna under test is taken into account (9, 10) [27].…”

“…L-shaped slot and strip [5], horizontal slit and inverted L-strip on the ground [6], L-shaped slot and partial ground plane with different heights on either side of the feed line [7] are adopted to improve the ARBW. A CPW-fed planar antenna having quadrilateral shaped radiating copper and an asymmetric ground plane is illustrated in [8]. Wide impedance bandwidth is attained by inserting a step-impedance resonator in the central feed line.…”

Circular polarization is manifested by means of truncations on basic circular radiating patch with precisely designed asymmetric feed. The proposed truncated circular microstrip antenna (TCMA) yields impedance bandwidth (IBW) of 7.6 GHz, almost covering the FCC approved ultra-wideband (UWB) frequency and 3-dB axial ratio bandwidth (ARBW) of 5.05 GHz spreading over two bands, enabling the antenna to be used for multiple applications in UWB frequency range. A peak gain of 5.73 dBi is documented at 5 GHz which is within the circular polarization (CP) band. This single feed antenna is very simple to design and compact in size.

This paper presents a compact antenna with co-planar waveguide (CPW) feed line for ultra-wideband (UWB) applications. The proposed antenna consists of a beveled radiating patch with wide rectangular slit at its upper side and a partial ground plane with insertion of symmetrically two-step beveled tapers at its center and sides, which provides a wide operating bandwidth. The antenna is integrated with narrow rectangular-shaped parasitic elements with different lengths placed adjacent to radiant patch to significantly enhance the impedance matching and bandwidth, especially at the upper frequencies. The measured results show an |S11| less than -10 dB bandwidth of 2.5-19.8 GHz with 155% fractional bandwidth. Simulation results are in good agreement with experimental measurements, which exhibits the validity of the proposed design approach. Moreover, the proposed CPW-fed antenna shows omnidirectional radiation patterns with stable gain within the operational range. The proposed compact antenna with low profile, light weight, large frequency bandwidth, ease of fabrication and low cost material is suitable for UWB applications.
