“…The literature reports on many optimization methods to design antennas; the return loss S 11 (see, e.g., previous works 3,7,15,30,[32][33][34][35] ), gain and bandwidth, 36 and the VSWR, 16,18 among others. We choose to minimize the VSWR in this paper.…”

The growth of small communication devices has pushed designers to design compact-size antennas. These antennas must be low cost, lightweight, needed for mechanically robust construction, and ease of installation. In this paper, we use a novel genetic algorithm (GA) to produce an ensemble of compact self-avoiding (SA) antennas such that the voltage standing wave ratio (VSWR) is less than 2 at the desired frequencies (as a measure of efficiency); an optimization criterion to get a desirable multiband antenna in the ultra high frequency (UHF) band. First, the electromagnetic properties of these antennas are simulated using the method of moments in MATLAB. SA antennas form a particular set of dipoles introduced here by applying a novel backtracking algorithm. We also use a Lindenmayer system that generates the geometries by a Turtle graphics render to reach our goal. Next, we simulate the VSWR for 150,000 SA antennas with lengths L from 0.1 to 0.4 m; 10 different frequencies are chosen randomly within the UHF band to obtain our results. All the VSWR ≤ 2 are clustered using density-based spatial clustering of applications with noise algorithm (DBSCAN), so our method provides the frequency ranges where this condition is fulfilled. From this, we obtain the VSWR minimums used for the antenna design. Finally, as an instance, we use our results to select the appropriate size of a multiband antenna and, through genetic algorithms, modify the geometry to satisfy the design requirements.

“…On the other hand, different techniques have been reported to achieve multiband compact antennas [4][5][6]. Authors in [5] proposed a non-conventional multiband patch antenna design based on a Genetic Algorithm with a filtering aspect. Based on different fundamental steps, the developed script was performed to achieve good impedance bandwidth in frequency bands [3.7/5.5 and 7.2 GHz] that correspond to WiMAX/WLAN and X-band standards, respectively.…”

This article concerns the design of a new quad-band monopole antenna with a specific configuration and reduced size. The antenna design is based on a single step meander-line parasitic structure, parasitic stubs, and double inverted L-shaped defected microstrip structure units on the top side of the substrate, and double rectangular-shaped defected ground structure units along with partial ground plane on the bottom side. This design procedure allows to achieve quad-band characteristics and improve the impedance matching. The fabricated antenna prototype with overall dimensions of (0.24λ0 × 0.17λ0 × 0.013λ0) is operating at 2.55, 3.65, 4.65, and 5.8 GHz with fractional bandwidth about 7.7, 12.84, 9.23, and 12.8%, respectively. The antenna exhibits an omnidirectional and a monopole like radiation patterns in the H- and E-planes, respectively, with suitable gains between 2.1 and 3.75 dBi. The measurement results are in good agreement with simulation values, which indicates that the proposed antenna design is suitable for WiMAX, LTE B7 (2.52–2.75 GHz), Sub-6 GHz 5G (n77) (3.39 – 3.87 GHz), Sub-6 GHz 5G (n78) (4.4–4.86 GHz), and WLAN, LTE B46 (5.1–5.82 GHz) wireless applications.

“…Many methods for designing multi-band antennas have been reported in the previous literature, such as the resonator loaded slot multi-band antenna reported in [11], triple-band antenna design using annular ring reported in [12], multi-band antenna design based on Genetic Algorithm reported in [13], dual-band circularly polarized DRA (Dielectric resonator antenna) for sub-6 GHz reported in [14], multiband slot antenna design reported in [15][16][17], hexagonal gasket fractal multi-band antenna reported in [18,19], multi-band antenna design using Defected Ground Structure (DGS) reported in [20][21][22], and low profile multi-band PIFA antenna design reported in [23]. These antennas have many advantages, but there are some performances still to be improved, such as poor radiation properties (backside radiation, non-stable radiation for each band, large minor lobes), cost, and complexity for integration in circuits.…”

This article presents a T-Shaped Tri-Band (TSTB) antenna based on the Characteristic Mode Analysis (CMA) for satellite applications. Tri-band characteristics are achieved by exciting two orthogonal radiating modes for the L5-band and L1-bands, and one higher order radiating mode for the S-band. Initially, cavity model theory is applied to a rectangular antenna to calculate orthogonal modes (T M z 010 & T M z 001 ) at L5-band and S-bands, and these modes are validated using the CMA method. With the help of surface current study and modification of a rectangular antenna, the one higher order radiating mode and orthogonal modes are excited by using the CMA method. All desirable radiating modes are excited by a single coaxial feed line in full-wave simulation, which is based on FIT (Finite Integration Technique). The proposed antenna's measured operating frequencies are 1575 MHz (L1-band) for GPS (Global Positioning System) system, 1174 MHz (L5-band), and 2495 MHz (S-band) for IRNSS (Indian Regional Navigation Satellite System
