“…Accordingly, the multiband antenna is desired in many systems. In the literature reviews, there are various multiband antennas that have been developed over the years, which can be utilized to achieve the objectives of multiband operation, for instance, the PIFA [1,2] for using in mobile phone application, the slot spiral antenna [3] for dual band or multiband operation, the triangle-shaped monopole antenna [4], and other [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. Recently, the developing multiband antennas have been improved due to use of the fractal concept.…”

Abstract-This paper presents a multiband slot antenna with modifying fractal geometry fed by coplanar waveguide (CPW) transmission line.The presented antenna has been designed by modifying an inner fractal patch of the antenna to operate at multiple resonant frequencies, which effectively supports the digital communication system (DCS 1.71-1.88 GHz), worldwide interoperability for microwave access (WiMAX 3.30-3.80 GHz), IMT advanced system or forth generation mobile communication system (3.40-4.2 GHz), and wireless local area network (WLAN 5.15-5.35 GHz). Manifestly, it has been found that the radiation patterns of the presented antenna are still similarly to the bidirectional radiation pattern at all operating frequencies. The properties of the antennas, for instance, return losses, radiation patterns and gain are determined via numerical simulation and measurement.Corresponding author: C.

“…Slots prove advantageous as there will be flexibility in optimizing the structure according to the requirement. Other important design considerations such as stacked antenna which is probe fed, use of thick substrate, use of feeding and impedance matching technique also prove beneficial to overcome the limitation of narrow bandwidth [8][9]. When considering feeding a particular antenna, there are many ways proposed over the years for given necessary input to the antenna.…”

In this paper, microstrip antenna array is considered. The resolution of the array is considered to be (2X1). The dimensions of the proposed antenna (width and length in 'mm') are taken as 8.3 mm x 5.75 mm. Also to improve the radiation properties combined H and dual U slots are cut on the antenna array elements. The theoretical calculations are done according to the considered dimension parameters using the standard patch antenna parameters, where the resonant frequency is found out to be "11 GHz". Now the proposed antenna is simulated using HFSS software. The ground plane is considered with the dimensions 26 mm x 16 mm. The dielectric is taken to be FR4 epoxy substrate. Strip-line feeding (inset-fed) is used to feed the antenna array. The simulated results showed the proposed antenna to be working at 11.03 GHz with return loss of-31.10 dB and a VSWR of '1.05'. Also the results are compared with the H slot microstrip antenna array and the dual U slot microstrip antenna array. All the necessary findings are tabulated and plotted.

“…Additionally, when they have slotted structures of various forms, they can enhance the bandwidth to such a degree that multi bands can be covered simultaneously. In addition, radiation loss in these antennas has been reported to be much lower [1][2][3][4][5]. Obviously, it is much preferable to take advantage of only one single multiband antenna instead of several antennas which is able to operate in different frequency bands.…”

The Optimization Design of a Novel Slotted Microstrip Patch Antenna with Multi-Bands Using Adaptive Network-Based Fuzzy Inference System

This paper attempts to apply an adaptive network-based fuzzy inference system (ANFIS) for analysis of the resonant frequency of a single-layer single-patch microstrip rectangular patch antenna with two equal size slots which are placed on the patch in the form of parallel to resonance edges. The resonant frequency is calculated as the position of the slots is shifted from the right endpoint to the left endpoint on the patch between −4.2 mm ≤ Xslot ≤ 4.2 mm with the steps of 0.1 mm. The designed antenna is proposed for downlink of X band satellite, broadcasting satellite service, fixed-satellite service uplink, satellite (Earth-to-space), radio navigation, mobile-satellite (Earth-to-space), and KU band which can be achieved at the resonant frequencies of 7.2 GHz, 12.2 GHz, 14.6 GHz, 17.5 GHz and 19.3 GHz. Next, High Frequency Electromagnetic Field Simulation software (ANSYS HFSS) results for the prototype microstrip antenna are compared with the values obtained through ANFIS system. It can be concluded that the adaptive network-based fuzzy inference system in such designs can be conveniently used due to fuzzy system's high approximation capability and much faster convergence rate. The best results for our ANFIS system can be obtained if Gaussian membership is used which leads to the mean absolute error of 1.4653.
