“…The performance of the proposed hexa‐band antenna was further evaluated by comparing it in terms of antenna size, realized gain and frequency bands covered to the state‐of‐the‐art multiband monopole antennas as listed in Table . Although the size of our antenna was comparable to others, it was the results, in terms of minimum resonance loss (–10 dB) and realized gain, that we offer better to the current available multiband antennas in literature . Measured and simulation results of the antenna agree to each other, thus offering good communication characteristics and features that make the proposed hexa‐band antenna a viable candidate for modern wireless communication and next generation multifunction systems and applications.…”

International audienceIn this letter, a hexa-band printed monopole antenna composed of various L-shape radiating elements is presented for various wireless applications. The antenna is designed to fully cover the CDMA (870-890 MHz), GSM (900-1800 MHz), DCS (1710-1880 MHz), PCS (1900 MHz), LTE-E/LTE-D (2300-2800 MHz), and WLAN (2.45/5.8 GHz) frequency bands. The proposed antenna achieves a gain of 1.8 dB, 3.17 dB, 3.23 dB, and 5.82 dB at respective bands. Fabrication of the antenna is completed on Rogers RT-5880 high frequency laminate with a finite ground plane having a rectangular slot on the other side of the substrate. The antenna is realized via standard printed circuit board (PCB) technology and its performance is validated by measurements in terms of s-parameters and radiation characteristics

“…Today´s handsets support video streaming, multimedia and fast surfing internet that is enabled by the Long Term Evolution (LTE) standard, what is commonly referred to as 4G . The recent explosion in 4G communication technology has led to portable devices such as notebooks or laptop computers, operating on the LTE bands, namely LTE 700MHz, LTE 2400MHz, and LTE 2600 MHz; several LTE antenna designs have been reported recently [7][8][9][10][11][12], but are rigid in their design to cover new design frequencies to cover these lower frequency operational designs.…”

“…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.

Specific absorption rate (SAR) by next-generation 5G mobile devices has become a burning question among engineers worldwide. 5G communication devices will be famous worldwide due to high-speed data transceiving, IoT-based mass applications, etc. Many antenna systems are being proposed for such mobile devices, but SAR is found at a higher rate that requires reduced for human health. This paper presents a metamaterial absorber (MMA) for SAR reduction from 5G n78 mobile devices at 3.5 GHz. The MMA is co-polarization insensitive at all possible incident angles to ensure absorption of unnecessary EM energies obeying the Poynting theorem for energy conservation and thus ensuring smooth communication by the devices. The unit cell size of the absorber is 0.114 $$\lambda$$ λ making it design efficient for array implementation into mobile devices. This absorber has achieved a minimum of 33% reduction of SAR by applying to the 5G n78 mobile phone model, equivalent to SAR by GSM/LTE/UMTS band mobile phones and making it suitable for SAR reduction from next-generation 5G mobile devices.
