“…In recent times, antenna researchers begun to look in the direction of bioinspired structure such as leave shape [4][5][6][7][8], the physical shape of animals [9], or internal organ shape of the animals [10] which has been explored. Authors in [4,7] proposed a bioinspired UWB antenna based on Igna Marginata leaf. e antenna proposed in [7] has dimension of 40 × 30 mm 2 and is built on an FR4 substrate of height 1.5 mm.…”

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.

“…However, although there are several advantages with the UWB standard, and in particular with UWB antennas such as wide bandwidth, low power consumption, and high data-rate wireless connectivity among devices within a personal operating space, the above mentioned antennas operating in such systems are limited to a carrier frequency ranging between 700MHz and 2600 MHz as in [1][2][3][4][5][6][7][8][9][10][11][12], and from 3GHz to 10GHz as in [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33]. Still the antennas on offer are not flexible enough to provide tunning/coverage for frequencies outside this range.…”

In the current mobile networking regime, cellular service providers are continuously facing bandwidth constraints due the ever-growing demand for mobile services. As future emerging services become more rich in content, their QoS requirements become more stringent in terms of delivering high quality, low latency, and high bandwidth connectivity. This trend provided the impetus for 5th Generation (5G) cellular networks that are anticipated to be deployed in the coming years. A distinguishing feature for 5G is the use of millimetre wave technology as a means towards harnessing more available bandwidth. This places new design requirements on the antenna technology in terms of miniaturisation and multimode connectivity. This chapter describes a family of future antennas for 5G wireless mobile communication. These antennas constitute a rectangular patch element printed over 0.8mm RF4 substrate. The antennas have a simple structural layout and have low profile with over-all volume of 5x5x0.8mm 3 .For bandwidth improvement purpose, a defected ground plane (DGP) approach was implemented, which demonstrated a broadband impedance response in the millimetre wave (mmW) spectrum from 30GHz to 45GHz, covering Ka band. Furthermore, an L-shaped slot was inserted over the right bottom corner of the patch in order to generate a notched-band feature at 40GHz. To tune this rejected band, a lumped capacitor was attached on a appropriate location over the slot. The proposed antennas have good performance in terms of return loss, bandwidth coverage, antenna gain, and high efficiency over the entire frequency range.

“…UWB antennas have gained huge consideration in the academia and industry for applications in wireless transmission systems. Thus, several antennas designs with numerous approaches were exploited to enhance the bandwidth coverage and enable the antenna to operate in the UWB frequency range [14][15][16][17][18][19][20][21]. Moreover, as there exists some standard narrow band standards within the UWB frequency region such as the wireless local area network (WLAN) for IEEE802.11a operating at 5.15-5.825GHz band, IEEE 802.…”
