“…Dengan menggabungkan kedua-dua jenis mod antena, ia meliputi operasi GSM 850/900 dan LTE 2300/2500. Untuk band rendah (dari 824 hingga 960 MHz), keuntungan antena dan kecekapan keseluruhannya adalah kira-kira 0.3 hingga 1.7 dBi, dan 45 hingga 60% dan juga bagi band operasi atas (daripada 1710 hingga 2690 MHz), keuntungan dan jumlah kecekapan masing-masing adalah 1.2 hingga 4.2 dBi dan 47% (Zhang et al 2017).

ABSTRAKPerkembangan lalu lintas dalam sistem komunikasi tanpa wayar telah menarik banyak pihak menumpukan perhatian kepada spektrum jalur lebar luas dalam gelombang frekuensi millimeter yang merupakan keperluan komunikasi generasi kelima (5G). Inspirasi antena yang boleh dikonfigurasi frekuensinya berasaskan metabahan dicadangkan untuk komunikasi 5G. Ia terdiri daripada garisan suapan lurus ekakutub dengan dua resonator cincin yang berpecah dua (DSRR). DSRR dibangunkan oleh resonator cincin berpecah luar dan dalam dengan jalur logam tembaga E-bentuk terbalik yang dihubungkan dengan resonator cincin luar. Teknik Integrasi Terhad berasaskan simulator elektromagnet CST Microwave Studio digunakan untuk reka bentuk dan kajian berangka. Pulangan Kerugian (S 11 ) menunjukkan resonan dalam 32.08 GHz, 35.07 GHz, dan 41.60 GHz. Prestasi antena yang boleh dikonfigurasi dicadangkan dianalisis dengan mengaktifkan atau menyahaktifkan DSRR. Walau bagaimanapun, metabahan yang direka menunjukkan ciri-ciri lengan kiri, padatan dalam ukuran dan lebih bersesuaian untuk aplikasi gelombang tanpa wayar 5G. Kata kunci: Aplikasi 5G; konfigurasi antena; metabahan lengan kiriABSTRACT Traffic development in the wireless communication system has attracted many parties concentrating on a broad bandwidth spectrum in the wave of frequency millimeters which is a fifth generation communication requirement (5G). Inspired antennae that can be configured by its own metamaterial is suggested for 5G communication. It consists of a straight feed line monopole with two resonator rings that split to two (DSRR). DSRR was developed by resonator the external split ring and in with the brass metal stripe of an overturned E-form linked to the resonator of the outer ring. Limited Integration techniques based on electromagnet CST Microwave Studio is used for numerical design and investigation. The Return of Loss (S 11 ) showed a resonant in 32.08 GHz, 35.07 GHz and 41.60 GHz. The antenna performance that can be configured is analyzed by activating or deactivating DSRR. However, metamaterial designed shows the characteristics of the left arm, a measure in measurements and is more appropriate for the 5G wireless wave application.

A multimode antenna for sub‐6 GHz applications in metal‐rimmed mobile terminals is presented. The proposed antenna is composed of a multibranch driven strip, a parasitic grounded strip, and an integrated metal rim that is connected to the ground through two shorting stubs. The proposed antenna occupies a 5‐mm clearance area, featuring simple design without lumped components. The working principle of the antenna is analyzed in detail in terms of its multiple resonant modes and current distributions. The resultant |S11| ≤ −6 dB impedance bandwidth of the antenna covers the LTE 700/2300/2500, UMTS, GSM 850/900, DCS, PCS, and recently proposed n77 to n79 5G NR frequency bands. The prototype of the antenna is fabricated and the design is well validated by experimental results.

“…Many multiple-band antennas for mobile phones with small ground clearances have been proposed in the literature [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. There are some useful methods to achieve compact and multiple-band antennas, such as using coupled feeding [1][2][3][8][9][10], lumped elements [4][5][6]11,12], and reconfigurable ways [7,[15][16][17]. The antennas in [1][2][3][4]6,7] can work at eight bands, but the 3.5 GHz band is not covered.…”

A compact antenna with a 6 mm ground clearance for 4G and 5G metal frame mobile phones is proposed in this paper. The proposed antenna consists of a coupled line, a ground branch, a monopole branch, and a tuning line. The ground branch and the coupled line are used to obtain the lower band (698–960 MHz), the monopole branch is used to improve the match at the lower band and obtain the higher band (1710–2690, 3400–3800 MHz), and the tuning line is used to improve the match at the higher band. The novelty of the proposed antenna is that more modes are excited and work together to obtain multiple working bands, by using the coupled line and the folded branches with the help of the tuning line, and then nine bands are obtained under the conditions of a 6 mm, only, ground clearance and a metal frame environment. A prototype has been fabricated and measured. The measured −6 dB impedance bandwidths are 345 MHz (0.685–1.03 GHz) and 2.16 GHz (1.67–3.83 GHz) at the lower and higher bands, respectively. The LTE700, GSM850, GSM900, DCS, PCS, UMTS, LTE2300, and LTE2500 bands for 2G, 3G, 4G, and the 3.5 GHz band that is possible for 5G are covered. The measured efficiencies and patterns are also presented.
