“…For instance in [4] matching impedance BW can be improved by the generated parallel meander lines and capacities in between. A wideband SMP antenna is introduced in this letter for improving the conventional meander-line antennas' BW to 2.2 GHz, with a size of 100 35 mm and BW ratio of 79%.…”

Two different antennas constructed using a new concept, the slot meander patch (SMP) design, are presented in this study. SMP antennas are designed for fourth-generation long-term evolution (4G LTE) handheld devices. These antennas are used for different target specifications: LTE-Time Division Duplex and LTE-Frequency Division Duplex (LTE TDD and LTE FDD). The first antenna is designed to operate in a wideband of 1.68-3.88 GHz to cover eight LTE TDD application frequency bands. Investigations have shown that the antenna designed with unequal meander widths has a higher efficiency compared to its equivalent antenna design with equal meander widths. The second antenna was configured as a multiband SMP antenna, which operates at three distinct frequency bands (0.5-0.75, 1.1-2.7, and 3.3-3.9 GHz), to cover eight LTE FDD application bands including the lowest and the highest bands. There is a good agreement between the measurement and simulation results for both antennas. Moreover, parametric studies have been carried out to investigate the flexible multiband antenna. Results have shown that the bandwidths can be improved through adjusting the meander widths without changing the SMP length and all other parameters. Index Terms-LTE antenna, LTE-FDD frequency bands, LTE-TDD frequency bands, slot meander patch.

“…It can provide excellent high‐definition video and audio through a compact factor, with outstanding multimedia and application capabilities . A number of antennas operating in the UHF band have been designed and applied to various devices, such as laptop computers, mobile phones, universal serial buses, portable personal computers, and portable media players as well as heavy equipment, such as vehicles . However, these antennas cannot be used in TV models because of the difference in requirements and structure of a signal‐receiving antenna for UHD‐TV applications.…”

“…For example, the antennas are external antennas having a large size, making them difficult to be integrated into a slim UHD‐TV. In other works, the antennas had either omnidirectional characteristics or very low gain . An internal antenna is intended to be integrated into a slim UHD‐TV, rendering the antenna susceptible to electromagnetic interference (EMI) from components, circuits, and sources inside the TV.…”

An internal antenna with bandwidth and directivity enhancement was developed for operation in ultra‐high‐frequency bands (UHF: 470‐771 MHz, bandwidth: 48.5%) for ultra‐high‐definition television (UHD‐TV) applications. The antenna is integrated into a 49‐in. TV model, which is surrounded by a bezel frame made of polycarbonate‐acrylonitrile butadiene styrene (PC‐ABS) plastic. This material was also used as a substrate in fabricating the antenna. The antenna has a compact size of 0.387λL × 0.023λL × 0.0093λL (where λL is the wavelength at the lowest operating frequency) and is fed by a 50 Ω coplanar waveguide (CPW) feedline. To achieve wideband operation and directional radiation, the proposed internal antenna was designed on the basis of a folded monopole antenna loaded with parasitic strips and an interdigital capacitor. The experimental results showed that the antenna exhibits a wide impedance bandwidth of 86% (400‐1000 MHz) under the criterion |S11| ≤ −6 dB (Voltage Standing Wave Ratio (VSWR) ≤ 3), a directional radiation pattern with a maximum realized gain of 5.2 dBi, and a radiation efficiency of more than 68%. These findings indicate that the antenna is suitable for UHD‐TV applications.

In this article, we propose a compact antenna using S‐shaped shorted strip and inverted L‐shaped shorted strip for 4G mobile handset. The measured impedance bandwidth defined by VSWR < 3 of 750 MHz (0.66–0.81 GHz), 2.6 GHz (2.25–2.85 GHz) and 3.5 GHz (3.28–3.97 GHz) are obtained, with the peak gains of 3.0/4.7/3.6 dBi. The presented antenna has a small size of only 21 × 15 mm2 and demonstrates omnidirectional radiation patterns, which show good performance for 4G application. The measured results are in agreement with the simulation. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:2199–2203, 2014
