“…With the development of integrated circuit and component technology, the size of these devices is decreasing, and the demand for antenna integration is increasing. In recent years, design methods of printed monopole antennas with various structures have been proposed [3][4][5][6][7][8][9][10]. For instance: tapered meander line [3], folded meandering branches [4], half-cutting method [5], shorted pin connecting ground [6], meandered split-ring slot [7], loading rectangular patch [8], and coplanar waveguide (CPW) feeding monopole antenna [9,10].…”

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.

“…Compared with the overall antenna size, the overall antenna size we designed is smaller than [55,56]. However, if we use system ground size to compare, its system ground size is [55,59], and this antenna size is smaller than [55][56][57][58][59]. Comparing the operating frequency and bandwidth, this design is the most continuous and extremely wideband design.…”

A miniaturized internal antenna with monopole structure is constituted, including three radiating strips of a compact prototype and a back-coupling pad to improve the impedance matching, which achieves a wide bandwidth of 2.972 GHz between the operating frequencies of 2315–5285 MHz, and is introduced and researched. There is an urgent need for a complete frequency-continuous and large bandwidth design in the current wireless communication design to achieve a multimode, multifrequency, physical phenomenon design with large bandwidth and continuous operating frequency. The recommended antenna provides a broadband operation in an electric vehicles (EVs) and Internet of Things (IoT) devices application embedded in the wireless communication standard for 5G, LTE, V2X, WLAN, WiMAX, Sirius/XM Radio, V2X, and DSRC to support the multiband application. This design is embedded side edge of overall placement in the device and is integrated applicable to the trend of heterogeneous wireless multiple access networks in electric vehicle and Internet of Things system devices, which covered the 5G with supporting the band of n7/n38/n40/n53/n77/n78/n79/n90, the 4G with supporting the band of 7/38/40/41/42/43/48/67, the V2X and DSRC for the operating frequencies between 2500 and 5000 MHz, the Sirius/XM Radio for the operating frequencies of 2320–2345 MHz, the ISM band of WiFi and BT covering the band of 2450–2483.5 and 5150–5350 MHz, and the WiMAX also supporting the band of 2300–2690 and 3400–3690 MHz. Moreover, the compact antenna manufactured an FR4 material with the antenna area of 5 × 10 × 0.8 mm3 and the ground area of 33.5 × 10 × 0.8 mm3. The proposed design better benefits a narrow space on the PCB with a low profile and is easy to make with a circuit board design.

In this paper, a novel printed monopole antenna loaded by a stepped impedance hairpin resonator (SIHR) with radial stubs is presented. By loading a SIHR at the bottom of the printed monopole antenna, a printed monopole antenna can be achieved. The resonant frequency of the proposed printed monopole antenna is reduced by the strong coupling between the SIHR and the printed monopole. By utilizing electromagnetic simulation software CST, the antenna is simulated and optimized. After the principle is stated, a sample antenna has been fabricated and measured to verify the predicted performance of our proposed antenna.
