“…Two angular parameters: θ 11 + θ 12 and θ 21 + θ 22 are attributed to the two arc-shaped slots to control their locations, lengths and widths with the aid of the parameters r 1 , ϕ 1 and r 2 , ϕ 2 , respectively. The whole structure is designed and realized on an FR4 30 × 28.5 × 0.8 mm 3 substrate with a relative permittivity ε rs = 4.4 and loss tangent of 0.017. and realize the multi-band function, these include using new feeding techniques [20], Defected Ground Structures (DGS) [10] [21-23], parasitic elements [24,25], Metamaterial [26,27], etc. Dual or multi-band characteristics are in great demand for various applications such as wireless local area networks (Bluetooth, WLAN, and WiMAX) and Industrial Scientific and Medical (ISM) applications.…”

“…In this frame, various designs of multi-band slot antennas have been proposed [11][12][13][14][15][16][17][18][19]. Moreover, several techniques have been proposed in the literature to enhance the parameters of conventional microstrip slot antennas and realize the multi-band function, these include using new feeding techniques [20], Defected Ground Structures (DGS) [10,[21][22][23], parasitic elements [24,25], Metamaterial [26,27], etc. Dual or multi-band characteristics are in great demand for various applications such as wireless local area networks (Bluetooth, WLAN, and WiMAX) and Industrial Scientific and Medical (ISM) applications.…”

In this paper, a new miniaturized compact dual-band microstrip slot antenna is presented. To achieve the dual-band characteristics, two adjunct partial arc-shaped small slots are joined to two main circular slots embedded in the ground of the antenna structure. With a reduced size of 30 × 28.5 × 0.8 mm3, the proposed antenna presents a dual-band characteristic. The design is optimized using a High Frequency Structure Simulator (HFSS) followed by experimental verifications. An impedance bandwidth, for S11≤10 dB, that covers the 1.8 GHz and 2.4 GHz bands is accomplished, which makes the proposed antenna basically suitable for hand-held devices and medical applications. More applications such as digital communication system (DCS) 1.71–1.88 GHz, personal communication services (PCS) 1.85–1.99 GHz, Universal and mobile telecommunications system UMTS 1.92–2.17 GHz, Bluetooth 2.4–2.5 GHz, and Wi-Fi 2.4–2.454 GHz, Industrial Scientific and Medical radio frequency (RF) band ISM-2.4 GHz, Wireless Local Area Network (WLAN-2.4)are possible by simply changing one of the geometrical antenna dimensions. The antenna is characterized by stable radiation patterns as well.
