“…In Figure , it is also found another advantage of employing the DMS‐spur‐line combination in comparison to other techniques: The radiation pattern shape is kept, and no nulls are obtained at the main direction as in Refs. [ ]; besides, a positive gain in all the resonances is obtained. When using just DMS, or a different combination of DMS‐spur‐line, the higher modes produced a radiation pattern where a null in the main lobe is obtained.…”

“…More publications demonstrate the use of slots in patch antennas in order to obtain multiband operation. The shape and length of the slots are directly proportional to the performance of the antenna; nonetheless, like every technique, there are advantages and drawbacks depending of the structure configuration, like reducing the bandwidth, lowering the gain, or even the efficiency …”

In this article, a simple but effective combination of DMS and spur‐lines is achieved to obtain a multiband patch antenna. The advantage of this technique is the simplicity to elaborate and the good performance compared to other methods where nulls are present in the radiation pattern at the main lobe. The antenna presents five resonant frequencies, which are fully controllable by modifying the dimensions of the defected microstrip structures and spur‐lines, obtaining the characteristic directive radiation pattern and maximum gain above 6 dBi in all bands.

“…The rapid growth in wireless communication demands for low cost, miniaturization, and compact multiband antennas. Multiband operation is one of the most important requirement for designing antennas used for multiple wireless communication systems, such as wireless local area network (WLAN) 2.4–2.484 GHz (specified by IEEE 802.11b/g) and 5.15–5.35/5.75–5.825 GHz (specified by IEEE 802.11a) and worldwide interoperability for microwave access (WiMAX) 2.5–2.69 GHz, 3.4–3.69 GHz bands (specified by IEEE 802.16e) and 5.25–5.85 GHz . In addition, the technologies like 2.4 GHz Bluetooth communication, WiFi (2.4–2.484 and 5.15–5.35 GHz), and RFID Tag Antenna (2.45GHz and 5.8GHz) also have great demands for compact multiband antenna systems.…”

“…The design method of multiband antennas involves various developed techniques. A multiband antenna can be obtained using multiresonators, defected ground plane structures, notched frequency bands, and fractal geometry techniques . Fractal antennas are very compact, multiband or wideband and have useful applications in wireless communications.…”

A novel multiband loaded trapezoidal ring fractal antenna (TRFA) is proposed for wireless local area network (WLAN) and worldwide interoperability for microwave access (WiMAX) applications. The self‐similarity property is applied to the trapezoidal structure and the fractal geometry is achieved by consecutive iterations. The proposed antenna has a compact size of 30 × 30 × 1.6 mm3. The antenna is fabricated and tested. The fourth iteration of the proposed TRFA covers the 2.4/5.2/5.8 GHz WLAN bands and 2.5/3.5/5.5 GHz WiMAX bands with uniform radiation characteristics and an average gain of 2.20 dBi. © 2014 Wiley Periodicals, Inc.

A circular loop antenna with C-strip line and frequency selective surface (FSS) ring resonator reflectors is presented. It can support multiband operation and enhance gain. The circular loop antenna is excited by using the coplanar stripe line, and a parasitic line is placed on the antenna to improve the impedance bandwidth of the upper frequency band. Moreover, the gain enhancement technique of FSS is applied to the antenna for achieving 7.54, 11.1, and 7.44 dBi at operating frequencies of 2.45, 3.5, and 5.25 GHz, respectively. The antenna's radiation patterns are directional patterns at all operating frequency bands. The presented antenna responds to the multiband operations of WLAN IEEE802.11 b/g (2.4-2.485 GHz), WiMAX (3.3-3.8 GHz), and WLAN IEEE802.11a .
