“…It may be observed that the radiation patterns at all these frequencies are stable and maximum radiations are directed normal to the patch geometry. The antenna could serve as a potential candidate for Ku band of satellite communication and other suitable applications having better radiation performance as compared to the recently reported works [14][15][16]. …”

This paper presents the design and synthesis of a nature-inspired micro-strip patch antenna based on the sunflower structure. The antenna structure was based on the Fibonacci pattern found in a sunflower, with the antenna elements in the position of the seeds. Simulation is done using computer simulation technology Microwave studio and the geometry offers impedance bandwidth of 5.28 GHz with enhanced radiation parameters. The geometry has simple structure, therefore can be used for satellite communication applications.

“…Some of the literature studies proposed antenna operating in wideband configuration to accommodate various bands. In Reference , annular ring microstrip antenna with finite ground is proposed with 52.02% impedance bandwidth from 3.3 to 5.7 GHz, but they fail to cover the 2G band and higher 5G sub‐6 GHz bands. In Reference , modified ground plane with open‐ended rectangular slots is presented, which successfully covers the 2G/5G bands but they suffer from low gain.…”

A multiband planar symmetrical plus‐shaped fractal monopole antenna with stepped ground plane is presented in this study. Measured results show that the proposed antenna operates with 10 dB return loss bandwidths from 1.630 to 1.88 GHz and from 4.5 to 8.5 GHz covering The Global System for Mobile Communications (GSM) 1800 MHz 2G spectrum band, 4400 to 4900 MHz 5G spectrum band adopted by Japan and China for future 5G communication in sub‐6 GHz band, 5.15 to 5.925 GHz LTE band 46, WLAN IEEE 802.11 y/a/h/j/n/P bands, and 5.8 to 7.707 GHz military band. The antenna gain varies between 1.73 and 1.97 dB in lower band and 3.6 to 5.05 dBi in upper band with radiation efficiencies more than 90% in lower band and more than 80% in upper band. The antenna has more than 64 and 28 dB isolations between the copolar and cross‐polar radiation patterns in the lower and upper bands, respectively.

“…Impedance matching at the lower operating frequency band have been reported in this case on introduction of stair‐shaped ground plane. Some other shapes such as circular disc, tulip‐shaped patch, and annular ring in the patch have been also proposed for obtaining ultra‐wide bandwidth . A comparison of the above‐reported structures in terms of overall size, the magnitude of S 11 (operational bandwidth reported) and substrate used for fabrication is shown in Table .…”

“…Some other shapes such as circular disc, tulip-shaped patch, and annular ring in the patch have been also proposed for obtaining ultra-wide bandwidth. [24][25][26] A comparison of the above-reported structures in terms of overall size, the magnitude of S 11 (operational bandwidth reported) and substrate used for fabrication is shown in Table 1. It can be clearly depicted from the comparison table that the proposed antenna exhibits UWB behavior in a very compact dimension of 15 × 20 × 1.5 mm 3 .…”

In this article, a compact UWB planar antenna with corrugated ladder ground plane is presented. The antenna has a compact size of 15 × 20 × 1.5 mm3. The proposed antenna is fabricated on low cost, easily available FR‐4 substrate with relative permittivity εr = 4.3, permeability μ = 1, and loss tangent of 0.025. The thickness of the FR‐4 substrate is 1.5 mm. The impedance bandwidth of the proposed antenna (magnitude of S11 <−10 dB) is 130.4% (2.4‐11.4 GHz). The peak gain of the proposed antenna is 3.5 dB and the peak radiation efficiency of the proposed antenna is 76%. Stable omnidirectional radiation patterns (H‐plane) and bidirectional radiation patterns (E‐plane) are observed in the entire operating frequency range. One side of the antenna with corrugated ladder ground plane results in the reduction of operating frequency of the proposed antenna and it reaches till 2.4 GHz whereas the other side of the antenna consist of the circular patch with a circular slot which results to resonant the proposed antenna in the higher operating band. With these properties, the proposed planar antenna is suitable for 2.4 (Wi‐Fi), 2.5/3.5/5.5 GHz (WiMAX) bands, 2.5/5.2/5.8 GHz (WLAN) bands, and other UWB wireless communication applications.
