This article focuses on the design of a CPW‐fed slot multiband antenna at frequency bands of 2.4, 3.5, 5.2, and 5.8 GHz, compliant the bandwidth requirements of the services that operate in these bands. The antenna is printed on a 30 × 32 mm2 FR‐4 substrate with thickness of 1.5 mm. Resonances are achieved by the use of a combination of slots of different geometries. The measured and simulated results prove that the proposed antenna is suitable for LTE, M‐WiMAX, Bluetooth, and WLAN applications. © 2016 Wiley Periodicals, Inc.

This paper focuses on the design of two CPW-fed slot multiband antennas. The first prototype works on four bands (2.4, 3.5, 5.2 and 5.8 GHz), and is printed on a 30x32mm2 FR-4 substrate with thickness of 1.5mm. The surface current distribution for each frequency is analyzed to introduce the different slots in the antenna. Following the same design procedure, the second antenna was obtained, this time for five bands (the four bands mentioned above and 1.7 GHz) and it was printed on 30x30mm2 of the same substrate. The measured and simulated results prove that the proposed antennas are suitable for LTE, M-WiMAX, Bluetooth, GSM and WLAN applications.
