“…The proposed MIMO antenna consists of two orthogonal elements with separation of 0.064λ at 2.4 GHz, and the whole antenna size is 19 × 33 mm 2 . The isolation between the two ports is greater than 22 dB in the entire operating bands.…”

“…In [1], three radiating strips are used to realize the triple bands to cover the WLAN/WiMAX frequency bands. In [2], an Hshaped slot antenna fed by microstrip coupling is presented to achieve multiband operation. A tri-band monopole antenna based on single-loop resonator (SLR) is reported in [3].…”

“…Compared to the antennas in [1][2][3][4][5][6][7][8][9][10][11][12], our proposed antenna configuration not only achieves the triple bands simultaneously, but also has a rather simple and smaller structure which is easy to fabricate with low cost. What is more, our proposed antenna configuration also allows for the independent adjustment of each operating bands within certain limits, which is an important aspect for practical applications.…”

“…To reduce complexity and make the structure simple, multiband aerial is required. H-shape, U-shape, and hexagonal slots with slits have been used to implement triple-band antennas [15,16]. Many papers based on hexagonal patches with fractal geometry have been published, including the following:…”

Abstract:The design and performance of an inset feed modified hexagonal patch antenna for possible applications in ultrawideband communication systems is reported. The inset feed hexagonal patch antenna is modified by introducing a fractal up to the second iteration. A right-angled isosceles triangular microstrip antenna is used in the Koch fractal structure on the edges. The proposed antenna is a combination of two standard fractal structures, i.e. Sierpinski and Koch. A rectangular defect in the ground has also been done. The antenna is simulated by applying CST Microwave Studio simulation software. The results are verified by fabricating the antenna and tested using a vector network analyzer.The developed design shows good matching with the feed network at frequencies of 3.1 GHz, 6.9 GHz, 7.3 GHz, 8.5GHz, and 9.1 GHz. The simulated peak gain of the antenna at resonant frequencies is 4.08 dB, 4.79 dB, 3.85 dB, 3.46 dB, and 3.01 dB. The antenna is fabricated on FR-4 substrate having size 30 × 35 × 1.59 mm 3 . It covers the S and X band range. It can be used for microwave applications as it is a part of the microwave spectrum, for wireless networking devices coming under IEEE standards. It can also be used for multimedia applications like mobile TV and satellite radio that use the S band as their frequency range and in home-based consumer electronics like microwave ovens, cordless phones, and wireless headphones. For higher ranges, i.e. in the X band, it can be used in radars, satellites, and military appliances.

“…Moreover, system compactness such as low-profile, lightweight and single-feed is also desirable to fit the limited equipment space of GPS, Wi-Fi and WiMAX devices. Hence, the printed antennas become good candidates to meet such requirement, and a lot of work has been reported on modelling the multi-band printed antennas [1]- [9] in the open literature. Generally, multi-band performance is realized by different resonating structure or resonator in the antenna.…”

Three parallel rectangular open slots (PROSs), etched on the ground plate of the printed antennas, is presented for multi-band applications. By employing the differential evolution (DE) algorithm to optimize the size and position of the PROSs, the reflection coefficient less than -10 dB at the global positioning system (GPS), Wireless-Fidelity (Wi-Fi) and worldwide interoperability for microwave access (WiMAX) bands, can be achieved without using the trial and error method. To evaluate performance of the proposed PROSs structure, a triple-band antenna (Ant I) is fabricated and measured together with a four-band antenna (Ant II). The measured results, which agree well with the simulated ones, show good impedance matching and nearly omnidirectional radiation patterns for each antenna. 1536-1225 (c) Index Terms-parallel rectangular open slots, multi-band, DE algorithm
