    Multi-band Circular Patch Antenna for Wideband Application
    (2013-08) Aabidi, Ebrahim S.; Kamarudin, M. R.; Rahman, T. A.; Iddi, Hashim U.
    This paper presents a multi-band circular patch antenna for wideband applications. The antenna operates at 1.5, 2.8, 4.0, 4.8, 7.5 and 8.8 GHz frequency bands. The antenna has been designed, simulated and fabricated on an FR4 substrate with dielectric constant ("r) of 4.4 and thickness of 1.6 mm. A dual feed approach has been used in the design of the proposed wideband antenna. The multi-band circular patch antenna is smaller than the conventional antenna for wideband application. The ¯nal optimized design is 50 £ 50mm2. The measured and simulated return loss results and simulated radiation pattern results of proposed antenna has been presented. The dual feed improves the gain of the proposed antenna. The measured and simulated results show that the proposed antenna provides good performance in term of return loss and radiation pattern for wideband applications.

    P-shape Monopole Antenna Design for WBAN Application
    (2013-03) Aabidi, Ebrahim S.; Kamarudin, M. R.; Rahman, T. A.; Iddi, Hashim U.
    This paper presents P-shaped monopole antenna for WBAN application for 3.1 to 5.1 GHz frequency band. The design and simulation of proposed antenna for WBAN applications in the free space and close proximity of body surface has been done using CST Microwave Studio. The proposed antenna was designed on the FR4 substrate with dielectric constant, "r of 4.4 and thickness of 1.6 mm. The ¯nal optimized design is 32 £ 28mm2. The antenna is suitable to be deployed for WBAN application.
