In this article, a novel printed multiband monopole antenna is presented for communication and navigation. The antenna adopts multi-branched structure simulating antlers to achieve multiband characteristics. The electromagnetic simulation software HFSS is used to model and analyze the designed antenna.The length and width of each antler branch and the shape and size of the grounding plate are optimized. A prototype antenna is fabricated on the FR4 substrate with the thickness of 1.6 mm. Experimental results have validated the design procedure of the antenna with a volume of 40 mm Â 50 mm Â 1.6 mm 3 and indicated the realization of the requirements for communication and navigation. The test working frequency bands are 1. GHz. It can be applied to GSM1800, 4G LTE33-41, Bluetooth, WLAN, WiMAX, and satellite navigation systems.

“…The working principle and performance of antennas are similar to those of the organisms in nature; hence, by imitating the structure of organisms to design the geometric structure of antennas, good performance can be obtained [5,6]. Examples include the use of plane-opposed Vivaldi miniature antennas inspired by natural ferns [7], a broadband antenna that simulates the shape of a ginkgo leaf [8], multiband antennas imitating banana leaves [9], and slot-shaped antennas imitating the shadow of butterfly wings under the sun [10,11]. The antenna can change the available frequency band from single frequency to dual frequency by adding semicircular arc branches to the circular monopole to form a "C + O" structure [12].…”

This paper incorporates the structural characteristics of chrysanthemums in nature and fractal geometry theory into the antenna structure design and a novel-structured fractal multiband fractal microstrip antenna with a chrysanthemum petal structure is proposed. The antenna can cover commercial frequency bands from the second to fourth generation (4G), satellite navigation, wireless local area networks, and Bluetooth. The antenna radiator imitates the structure of chrysanthemum’s petals in nature, and a basic arc shape is iterated many times according to a certain proportional coefficient. After simulation and comparison, the second iteration can achieve the best antenna performance, and the antenna adopted the coplanar waveguide feeding method to broaden the antenna bandwidth. The antenna covers three effective frequency bands of 1.58–2.68 GHz (64.7%), 2.76–4.01 GHz (33.9%), and 4.68–5.35 GHz (13.4%). The antenna dielectric board is made of FR-4 material, the dielectric constant is 4.4, and the actual size is 41 × 29 × 1.6 mm3. The antenna performs fractal iteration at a small size, and the approximate calculation of the frequency band is completed by comparing the ratio of each ring to the current vector diagram. The design of the antenna is to use HFSS for antenna modeling and parameter optimization, and the model under different conditions were compared and analyzed. By comparing the test results of the antenna prototype with the simulation structure in the electromagnetic anechoic chamber, the rationality of the antenna is verified.

“…Self-similarity in fractal antennas permits the achievement of similar surface current distributions in different planes as well as multifrequency characteristics; space filling enables the increase of the antenna electrical length [15,16]. Furthermore, it has been shown that the frequency band of antennas can be increased by adding branches and slits [17,18]. In order to reduce the size of antennas, it is important to note that the size of the dielectric resonant antenna (DRA) is proportional to the parameter λ/ε 1/2 r .…”

This work proposes a novel multiband slotted planar antenna with a “回” structure, which is similar to an ancient Chinese window grille structure. The antenna is suitable for wireless applications, including the second-generation (2G), third-generation (3G), fourth-generation (4G), and fifth-generation (5G) technologies, as well as WLAN and navigation applications. The proposed antenna is based on the structural characteristics of a conventional monopole antenna, which combines the advantages of a slit structure and microstrip line structure for feeding. It adopts a circular patch with a slit structure placed in it, which is similar to the Chinese classical pane structure. This structure enables an effective reduction of the size of the antenna. The four-sided “回” gaps change the path of current flow and are coupled to each other, improving the impedance matching and radiation characteristics of the entire target frequency band. The antenna covers the frequency ranges of 1.58–1.77 GHz (12%), 2.1–2.50 GHz (17%), 3.61–4.09 GHz (12%), and 4.75–6.5 GHz (36%), permitting more than 10 wireless applications in these 4 frequency bands. This antenna uses an FR-4 dielectric material; the relative dielectric constant of the dielectric plate is 4.4, and the actual dimensions of the antenna are 85 × 70 × 1.6 mm³. The test and simulation results are in good agreement with each other, thus confirming that the proposed design method meets the requirements of various wireless applications.
