“…In [18], by placing a meander line that acts as an NFRP element near the printed monopole antenna, the monopole is realized. In [19], a printed monopole antenna is achieved by a single fan-shaped top-loaded monopole as an NFRP element. In [20], a printed monopole antenna with stepped impedance hairpin resonator loading as an NFRP element has been presented.…”

In this paper, a novel printed monopole antenna with folded stepped impedance resonator (SIR) loading is proposed, designed and fabricated with a standard printed circuit board process. The antenna comprises of a printed monopole antenna and a folded SIR with internal coupling etched on the back of the antenna. By loading this folded SIR as a near-field resonant parasitic (NFRP) element, the resonant frequency of the antenna can be reduced by the strong coupling between the folded SIR and the radiation patch of the printed monopole. After reviewing the theoretical analysis of the proposed printed monopole antenna, a prototype antenna has been fabricated and measured. The simulated results agree well with the measured results, and the prediction performance of the antenna is verified. Therefore, the proposed method in this paper is a promising candidate for printed monopole antenna design. INDEX TERMS Printed monopole antenna, near-field resonant parasitic (NFRP), folded stepped impedance resonator (SIR), coupling.

“…4 Metamaterials as a novel artificial electromagnetic media with unusual and useful properties are widely used in various antenna design, [5][6][7][8][9] especially for miniaturized metamaterialbased antennas. [8][9][10] Several small metamaterial-based/inspired antennas were proposed in References 8 and 9 but they suffer from narrow bandwidth and large loss. Metasurface-based antenna achieves wide bandwidth response and high gain, but it costs a large dimension and complex periodic structure.…”

This paper describes a metamaterial-based miniaturized circularly polarized (CP) antenna with high radiation efficiency and wide beam-width or coverage for 5G indoor application. A novel meta-resonator is first proposed, which is investigated by transmission line and equivalent circuit models. By exploring a split-ring resonator-like metaresonator structure, a high-Q LC resonator tank is formed. Substantial size reduction and a wide beam-width are achieved. Owing to a uniform field on these multiple capacitive gaps incorporated on this meta-resonator surface, enhanced aperture efficiency and gain are obtained. It is partly inspired by the classical metasurface-based antenna. For validation, a miniaturized CP antenna with a size of 0.29 λ 0 × 0.29 λ 0 × 0.04 λ 0 (where, λ 0 is the free-space wavelength at 3.55 GHz) is fabricated and measured. The fabricated antenna achieves a good bandwidth of 3.30-3.80 GHz that well covers 5G-N78 band, a peak radiation gain of 5.4 dBic, a high radiation efficiency of 90% and a wide half-power beam-width of 91 . It exhibits the merits of compact size, good bandwidth and beam-width, high efficiency, and low-cost, demonstrating good potential in miniaturized 5G indoor systems demanding wide-beam coverage.

“…With the development of integrated circuit and component technology, the size of these devices is decreasing, and the demand for antenna integration and miniaturization is increasing. Various techniques for designing compact monopole antennas based on different structures have been proposed [3][4][5], such as tape meander line [6], folded meandering branches [7], bent folded [8], embedded slots [9], meandered split-ring slot [10], loading rectangular parasitic elements [11], and coplanar waveguide (CPW)-fed slot antenna [12,13].…”

In this paper, a compact printed monopole antenna with periodic H-shaped slots for WLAN application is proposed, designed, and fabricated with standard flexible printed circuit board process. By cutting four H-shaped slots in the radiation patch of the printed monopole antenna, the resonant frequency of the monopole antenna can be reduced; therefore, a compact antenna is realized. The radiator size of the antenna is 0.07λ g × 0.19λ g , which is much smaller than that of a traditional printed monopole antenna. By utilizing electromagnetic simulation software CST, the antenna is simulated and optimized. Moreover, the performance of the proposed antenna is discussed taking into consideration the possible effects of deformations due to the flexibility of the substrate. A sample antenna is manufactured and measured to prove the predicted performance of our proposed antenna. The measured results agree well with the simulations. Hence, the proposed method in this paper is a promising candidate for the design of compact antennas.
