In this study, a patch antenna with three different operating frequencies (2.94 GHz, 4.5 GHz, and 5.7 GHz) is proposed. The dimensions of the antenna are as follows: 23.4 mm by 30.4 mm by 1.6 mm. The triple band characteristic may be achieved by adjusting the width of the quarter wave transformer (QWT), which in turn modifies the impedance matching in such a manner as to excite the TM10, TM02, and TM12 modes. These modes are able to have additional verification provided by the current distribution on the patch. Altering the width of the QWT provides the proposed antenna with the ability to fine-tune its resonant frequencies. At the resonant frequencies, the impedance bandwidths of -10 dB are 69 MHz, 40 MHz, and 110 MHz, respectively. 5.7 GHz has a gain of 1.5 dB, while 4.5 GHz has a gain of 0.7 dB, and 2.94 GHz has a gain of 2 dB. Additionally, this antenna finds its applications in wireless systems in the S and C bands of the frequency spectrum. The antennas are validated using a vector network analyzer (VNA) after being simulated with mentor graphics software three-dimensional electromagnetic modeling (3DEM) and analyzed with it.

“…The length and width of the substrate and patch are the same due to the use of the coaxial probe feeding method which results in reduced antenna size. The feeding point is located near the edge of the antenna to get better impedance matching [23,24]. In comparison to traditional possibly antennas, modern telecommunications networks needed antennas with wider bandwidths and smaller dimensions.…”

Modern telecommunications systems required antennae along with wider bandwidths including the smaller dimension as compared to conventional possibly antennas [1,2]. It has initiated the antenna's research in various directions, one form which utilizes the fractal shape antenna's element [3,4]. There exist important relations between antenna dimensions and wavelengths. The relation states that if an antenna's sizes are lesser than the λ/4 then the antenna isn't effective because of the radiation's resistances, and gains, as well as the bandwidth, gets reduced [5,6]. Further, to overcome the limitation of the antenna's size got increased, which again problems with the handheld device. *Author for correspondence Fractal geometry is considered a pragmatic solution for the existing aforementioned problem [79]. The term fractal means the irregular or broken fragment. This is defined from Benoit's Mandelbrot derived from the Latin word 'fractus' that means fracture or the broken [1012]. The Fractal's antennas get inspired by the nature. A fractal antenna has two main properties that are space-filling as well as self-similarities [1315]. The space-filling properties reduced the size of antennas and this makes antennas electronically larger in the smaller physical spaces [1618]. Self-similarities property means that the patches of the antennas are subdivided into small parts as well as every smaller part is the smallest portion of the reduced sizes of main geometries [1922].

In this research, a multiband patch antenna design based on the superposition of multiple modes at the same resonant frequency is presented. The concept of the contribution of lower order modes (LOMs) with the higher order dominant modes (HODMs) is investigated using characteristic mode analysis (CMA). In order to provide similar broadside radiations in three bands, the radiating capability of the LOMs is enhanced in the resonant frequencies of HODMs. These HODMs when excited alone provide null in the broadside radiations of the antenna. Using a single feed, enhancement in the broadside radiations of the antenna is achieved with the superposition of multiple modes at the same resonant frequency. Based on the proposed concept two antennas have been designed and fabricated. The antenna provides stable and enhanced radiations. simulated and measured results are in good agreement. These antennas find application in many applications including communication systems, base station antennas, 5G communications, satellite communication etc.
