This article presents the design of a double‐psi‐shaped dual band antenna, modified from the conventional microstrip patch. The proposed antenna is printed on an FR4 epoxy substrate and it occupies a compact size of 17 mm × 18 mm × 1.6 mm. We have designed our antenna to operate at 2.4/5.15 GHz. The measurement results show that the proposed antenna has 10 dB impedance bandwidths of 1650 MHz (1.982–3.632 GHz) and 812 MHz (4.444–5.256 GHz) to cover the LTE and 5 GHz IEEE 802.11 WLAN bands, respectively. The geometry of the design is relatively simple—it constitutes only 2 U‐shaped strips appended to a conventional microstrip patch, producing a structure which resembles 2 psi (Ψ) letters placed on top of one another. Due to its simple configuration and good radiation characteristics, the antenna is an appropriate candidate for applications which require both wireless communication and internet services.

“…With the rapid growth in wireless communication systems, there has been significant improvement in the design of multiband antennas. Different designs for multiband antennas, applied particularly in Wireless Local Area Network (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX), can be found in . It can be seen from these literatures that most of the antennas are only designed to support dual‐band , tri‐band or ultra wideband (UWB) operation.…”

It can be seen from these literatures that most of the antennas are only designed to support dual‐band , tri‐band or ultra wideband (UWB) operation. Although the designs in support up to four operating bands, the antenna structures are either complicated and, therefore, difficult to be fabricated or the designs take up unnecessary space, resulting in large sizes.…”

We present the design of a novel compact coplanar waveguide‐fed antenna with fractal s‐shaped patches for multiband applications. The antenna consists of three fractal s‐shaped patches with different lengths. We demonstrate that the number of resonant frequencies is in direct proportion with the number of fractal s‐shaped patches. This is to say that, the number of resonant frequencies in a multiband antenna can be increased by increasing the number of patches. The resonant frequencies can be selected by carefully adjusting the length of the patches. We have designed our antenna to operate at 2.5/5.3/7.1/8.4 GHz. The measurement results show that the proposed antenna has 10 dB impedance bandwidths of 622 MHz (2.322–2.944 GHz), 466 MHz (5.113–5.579 GHz), 121 MHz (6.890–7.011 GHz) and 1080 MHz (8.206–9.286 GHz) to cover all the 2.4 GHz Bluetooth, 5.5 GHz WiMAX, and 2.4/5.2 GHz WLAN bands. The latter two bands of our proposed antenna fall within the X band range which finds vast applications in radar, aircraft, spacecraft and mobile or satellite communication system. The proposed antenna is printed on a single‐layered FR4 substrate, and it occupies a small volume of 17 × 18 × 1.6 mm3. The simulated and measured performance of the antenna confirms its omnidirectional radiation pattern and quad‐band operation. © 2017 Wiley Periodicals, Inc.
