“…In literature, for antenna miniaturization, enhancement of bandwidth, and to increase the number of operating frequencies, different methods are proposed for IoT applications. To improve the characteristics of antenna, asymmetric coplanar strip fed 2,3 is proposed. Insertion of multiple strips, such as bent, circular‐arc, and l ‐shaped strips, 4,5 is also proposed.…”

The investigation of two half circular patch (HCP) antenna with defected ground structure to operate dual bands is presented in this study for wireless communications. The crescent slots etched on the HCPs are proposed to operate the dual bands of below −10 dB reflection coefficient, with the impedance bandwidth of the first band being 740 MHz (3.01–3.75 GHz) and of the second band being 7120 MHz (6.74–13.86 GHz). The proposed HCP antenna was resonates of 3.36 and 12.17 GHz with −33.9 and −35.47 dB reflection coefficients. This antenna produces a maximum gain of 5.46 and 6.61 dB for these resonating frequencies, respectively. The simulation and measured radiation pattern results are also presented for proposed HCP antenna and it operates for wireless communications and internet of things applications.

“…Mainly, two types of feeding methods are used for realizing this type of antenna, microstrip line and coplanar waveguide (CPW)-fed based structures. The CPWfed technique has many advantages with respect to the microstrip feeding structure like single layer metallization, low dispersion, the ability for controlling the characteristic impedance, low radiation loss, and simplicity in structure by avoiding the use of via holes and shorting pins [2,3]. Thus, due to the foregoing features, the CPW-fed mechanism is adopted in this work for feeding the proposed antenna.…”

This paper presents a new compact dual-band slotted-ring monopole antenna (SRMA) with circular fractal elements (CFEs) design for WiMAX and C bands applications. Good improvements are obtained in widening the upper-frequency band of the proposed antenna and in miniaturizing its overall size. Antenna miniaturization is accomplished by employing a coplanar waveguide (CPW)-fed fractalshaped SRMA loaded at its inside and outside of the ring's peripherals by two types of CFEs, namely, CFE1 and CFE2. The dual-band capability of antenna is realized by introducing in its ring's center a circular slit to act as a key parameter for band rejection characteristic. The design procedure starts from a conventional circular monopole antenna (CMA), and evolution steps of antenna are performed until achieving the proposed CPW-fed SRMA with aforementioned features. The simulated results in terms of reflection coefficient, gain, efficiency, and radiation patterns are obtained by using CST MWS and HFSS programs. Due to the agreement between the CST and HFSS simulated results, the prototype of the antenna is fabricated on one side of an FR4 substrate with a volume of 20 × 22 × 0.8 mm 3 . Then the measured reflection coefficient is conducted, and it agrees well with the simulated counterpart. As observed from measurement, the antenna operates at two distinct bands of 3.15-3.75 GHz and 5.02-7.58 GHz that exhibits the proposed antenna to cover WiMAX, WLAN, C-, 4G LTE, 5G, and Sub-6 GHz bands. Also, the proposed antenna exhibits an acceptable gain and efficiency across the operating bands along with omnidirectional radiation pattern.

“…With the development of multiple wireless communications standards, group of engineers focus their interests on how to design multiband antennas that can be integrated as many standards such as WLAN, WiMAX, and satellite communication as possible into a single wireless terminal device. In order to meet these requirements, various types of promising multiband antenna designs were studied in [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Planar printed monopole antennas with various structures in [1][2][3] have become popular candidates in multi-frequency applications for its advantages of low-cost, low-profile, and easy fabrication, whereas the antenna size is relatively large which is not suitable to be installed in mobile wireless terminals.…”

“…In [4,5], the antenna only supports dual bands. Triple-band antennas covering the WLAN (2.4/5.2/5.8 GHz) and WiMAX (3.5/5.5 GHz) bands were presented in [6][7][8][9][10][11][12]. Although these antennas support triple bands, they cannot fully cover the required bands, which is a common problem of these antennas.…”

A CPW-fed compact multiband planar printed monopole antenna for WLAN/WiMAX/X-Band applications is presented in this paper. The structure size of antenna is 0.144λ 0 ×0.176λ 0 ×0.008λ 0 . The proposed antenna is composed of three monopole radiators, a microstrip feed line, and the ground with chamfer. With these structures employed, the antenna can generate four different resonances to cover the desired bands while maintaining low profile. The antenna simulation results show four distinct bands from 2.24 to 2.85 GHz, from 3.29 to 4.12 GHz, from 5.13 to 6.24 GHz, and from 6.58 to 8.57 GHz, which cover the entire WLAN bands (2.4-2.484, 5.15-5.35, and 5.725-5.825 GHz), WiMAX bands (2.5-2. 69,, and X-band satellite communication systems . For verification of simulation results, a prototype of quad-band antenna is designed, fabricated, and tested. The simulated and measured return losses, radiation patterns, and gains are presented. The proposed antenna possesses compact size, simple structure, high gain, and omnidirectional radiation pattern, which make it a suitable candidate used in small/portable WLAN/WiMAX/X-Band devices.
