    M-Shape Surrounded with Ring Patch Wideband Monopole Printed Antenna
    (Wiley, 2011-12-15) Aghda, Majid R.; Kamarudin, M. R.; Iddi, Hashim U.
    In this article, a novel shape of a ring printed antenna is presented. Antenna is designed for wideband applications. There is an M-shape patch inside the ring, which is optimized for wideband applications. The antenna operates between 2.05 and 6.85 GHz frequency bands. The measured bandwidth is about 107.87%. The proposed antenna has fabricated and tested. It has been fabricated on 30 × 51 mm2 FR4 board. A novel shape of ground plane has been used for increasing the bandwidth and removing some ripples in the result. The return loss results have been presented based on simulation and measurement. © 2011 Wiley Periodicals, Inc.

    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.
