    Design of Dual-Band B-Shaped Monopole Antenna for MIMO Application
    (IEEE, 2012) Iddi, Hashim U.; Kamarudin, M. R.; Rahman, T. A.; Dewan, R.
    A dual-band B-shaped monopole antenna for MIMO application is presented. The proposed antenna consists of B-shaped element which operates at dual band frequencies of 2.45GHz and 5.8GHz. The prototype has been fabricated and when tested, the impedance bandwidths are 29.9% and 33.8% for 2.45GHz and 5.8GHz, respectively. Good agreement between the measurement and simulation results in term of return loss and radiation pattern have been obtained.

    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.

    Planar Cone-Shaped Monopole Antenna with Tapered Ground for UWB Application
    (IEEE, 2012) Iddi, Hashim U.; Kamarudin, M. R.; Rahman, T. A.; Dewan, R.
    Compared to the narrow band antenna design, ultra wideband (UWB) antenna design has a lot of challenges. One of such challenge is the requirement that the return loss must be below 10dB bandwidth from 3.1-10.6GHz throughout the UWB frequency range. Other challenges include low cost, small size, light weight and good radiation patterns [1]. One of the characteristic of conventional planar monopole antenna have narrow impedance bandwidth due to their high quality factor [2].
