“…Jhamb et al [12] it uses the coaxial feed technique with defected ground structure (DGS) to create such a compact design but the bandwidth of the proposed frequency bands has been increased. Malik et al [13] have proposed a square patch antenna that operates in six different frequency bands, square loop elements are introduced to achieve multi-band characteristics, the proposed design is simple, on the other hand, it is larger in the area compared to the designs presented previously.…”

In this paper, a novel multi-frequency microstrip antenna with complementary ring slot resonator (CRSR) structure that satisfies Bluetooth, worldwide interoperability for microwave access (WiMAX), and wireless local area network (WLAN) applications is proposed. The conventional antenna consists of a circular microstrip patch at a resonance frequency band of 2.5 GHz. By loading two CRSR at the radiating element, three operating frequency bands 2.5 GHz, 3.6 GHz, and 5.2 GHz are achieved. The operational bands covered by the antenna are Bluetooth 2.5 GHz, WiMAX 3.6 GHz, and WLAN 5.2 GHz. The insertion of CRSR to patch antenna has made it possible to compact and simple design, and miniaturized antenna for cognitive radio. Moreover, the directivity of the proposed antenna is adequate with acceptable radiation properties and perfectly matches with the simulated and measured results.

“…Recently, several antenna con gurations have been designed and presented to achieve a multiband antenna satisfying the WLAN standards at the 2.4/5.2/5.8 GHz frequency bands, and the WIMAX recommendations for the 2.5/3.5/5.5 GHz bands [1][2][3][4][5][6][7][8][9][10]. Among the con gurations, inverted U-shaped slots printed on the metal patch [1], L-shaped, inverted L, and U-shaped slots embedded in the radiator element [2][3][4], a compact F-shaped antenna [5], a wide-slot monopole antenna [6], a double L-slot patch antenna [7], a ring monopole antenna [8], and a multiband antenna were realized by introducing squareloop elements into the square patch [9], and a dual broadband WLAN antenna [10]. In [11], a novel triband square-slot antenna with two identical L-strips was presented for WLAN and WiMAX communication.…”

In this article, we propose a coplanar waveguide (CPW) antenna for WLAN/WIMAX applications using the artificial neural network (ANN) technique. In order to attain the correct resonant frequencies for WLAN/WIMAX applications, we inserted three slots in the radiating patch to form an inverted U-shaped slot. To achieve antenna performance in the standard WLAN/WIMAX frequency band, we adjusted the position and dimensions of the inverted U-shaped slot. The ANN method helped to better predict the dimensions of the inverted U-shaped slot. To collect the datasets used for training the ANN structure, we wrote a Visual Basic (VB) script in order to control the HFSS simulator using MATLAB. After training the network, the dimensions of the inverted U-shaped slot could easily be predicted for the desired resonant frequencies. The predicted ANN dimensions were used to design the antenna using both CST and HFSS electromagnetic simulators. To better evaluate the CPW antenna performance, we study and discuss the reflection coefficient, radiation pattern, voltage standing wave ratio (VSWR), current distribution, gain, and radiation efficiency. A prototype of the proposed antenna was fabricated; the obtained results show |S11| ≤ − 10 dB in the frequency bands of 2.31–2.43 GHz, 3.10–3.44 GHz, and 3.94–5.88 GHz, which make the antenna suitable for WLAN/WIMAX applications.

“…* Correspondence: amin.honarvar@pel.iaun.ac.ir Due to the small size and low cost of such systems, there has been a surge of interest [4] in printed antennas. To cover multiple bands simultaneously, various antennas including a multiple mode monopole antenna, loop, and slot antenna have been proposed [4][5][6][7][8][9][10][11][12][13][14][15]. However, classic loop antennas are typically narrow band radiators that occupy much space.…”

In this article a thin hybrid multiband printed loop antenna is presented for application in multiple-input multiple-output (MIMO) systems. The proposed antenna has several advantages; for example, the pseudofilter feature of the proposed antenna is one of this antenna's advantages. Because of the antenna's width ( 9.5 mm), it can be used on the edges of the board. The first resonant frequency is generated by the original loop of the antenna. Incorporation of different embedded components, i.e. a subsidiary loop, extended ground-traces, parasitic patch, and the slits, results in the proposed antenna resonating as a multiband antenna. This antenna is adjusted in such a way that it resonant in WLAN ( 2.4 , 5.2 , and 5.8 GHz) and WiMAX ( 3.5 GHz) bands. Four antennas are used as a MIMO system that are sequentially and perpendicularly placed along the edges of the board. In conclusion, the antenna design is confirmed according to simulation results obtained from the constructed prototype and associated measuring results.
