    Dual-band Circular Patch Antenna for wideband application
    (IEEE, 2013) Alabidi, Ebrahim S.; Kamarudin, M. R.; Rahman, T. A.; Iddi, Hashim U.; Jamlos, M. F.
    A Circular Patch Antenna for wideband application is presented in this paper. The antenna has been designed, simulated and fabricated on an FR4 substrate with dielectric constant (εr) of 4.4 and thickness of 1.6mm. A dual feed approach has been used in the design of the proposed wideband antenna. The dual-band circular patch antenna is smaller than the conventional antenna for wideband application. The final optimized design is 40×50mm2. The measured and simulated return loss results and simulated radiation pattern results of proposed antenna has been presented.

    Novel Dual-Band B-Shaped Printed Monopole Antenna for MIMO Application
    (2013) Iddi, Hashim U.; Kamarudin, Muhammad R.; Rahman, Tharek A.; Jamlos, M. F.; Aghda, Majid R.
    Proposed antenna consists of B-shaped element which operates at dual-band frequencies (2.45 and 5.8 GHz). The antenna has been simulated using CST software and the prototype has been fabricated on FR4 substrate. The impedance bandwidths (BWs) that have been achieved are 29.9% and 33.8% for 2.45GHz and 5.8GHz bands respectively. The mutual coupling and correlation coefficient have also been investigated in which the antenna provides -22dB of mutual coupling and 0.02 of correlation coefficient. The proposed design achieves low mutual coupling and correlation coefficient at a separation distance of λ 12 between antenna arrays. There is good agreement between the measurement and simulation results in terms of return loss and radiation pattern.

    Triple-Band Cpw-Fed Planar Monopole Antenna for Wlan/Wimax Application
    (Wiley, 2013-06-23) Iddi, Hashim U.; Kamarudin, Muhammad R.; Rahman, Tharek A.; Abdulrahman, Amuda Y.; Khalily, Mohsen; Jamlos, M. F.
    A triple-band planar monopole antenna is presented in this article. The antenna consists of three strips which correspond to operating frequency bands of 2.4, 3.5, and 5.8 GHz. The proposed antenna has been designed, simulated, and fabricated on 20 × 38 mm2 FR4 board. There is good agreement between simulation and measurement results in terms of return loss and radiation pattern. The proposed antenna provides measured −10 dB bandwidths of 200 MHz for the 2.4 GHz (from 2.36 to 2.56 GHz); 620 MHz for the 3.5 GHz (from 3.48 to 4.10 GHz); and 1.38 GHz for 5.8 GHz (from 5.65 to 7.03 GHz). Moreover, the antenna provides the measured gain of 4.73, 1.66, and 3.28 dBi for 2.4, 3.5, and 5.8 GHz, respectively. The radiation characteristics have proven that the proposed antenna seems to be a good potential candidate for WLAN/WiMAX applications.
