Novel patch antenna for multiband cellular, WiMAX, and WLAN applications

: In this paper, a novel multiband patch antenna has been designed, simulated, and measured for GSM, DCS, IMT, WiMAX, and WLAN (IEEE 802.11 a/b/g/n) applications. The proposed antenna consists of a square patch and square-loop elements (connected through 50Ω microstrip line) excited by a coaxial feed. With the help of square loop elements, the antenna is able to provide multiband response. The proposed antenna occupies an overall size of 80 × 80 × 1.6 mm3 . The 10 dB bandwidth criterion offers good impedance bandwidth for desired bands. Moreover, gain of the proposed antenna is acceptable with good radiation properties. The proposed antenna is fabricated on FR-4 substrate and it is noted that the simulated and measured results are in good agreement.
