A modified printed bow-tie antenna is designed to simultaneously cover the operations in the C and X-bands from 5.5 to 12.5 GHz. The presented antenna has an end fire radiation pattern that makes it suitable for integration in single and dual polarized phased array systems. The antenna exhibits small size and wide bandwidth of 91%. The radiation characteristics are presented for a single element and a linear array of this antenna.

    ABSTRACT: This paper describes a novel ultra-wideband quasi-Yagi circular dipole antenna. The antenna consists of two parallel circular dipole radiators of different resonant lengths. The bandwidth which can meet both impedance and radiation characteristic requirements is greater than 100%. The important advantages of this antenna are ultra-wideband, directive property, and low cross polarization levels with high front to back lobe ratio. A prototype is fabricated and measured. Keywords—— Quasi-Yagi antenna, circular dipole antenna, wideband, Front-to-Back ratio, gain, director and reflector.

    • "Several quasi-Yagi (Kan et al. 2007) and bow-tie (Eldek et al. 2005) antenna provides wide bandwidth, but they do not give flexibility to choose specific frequencies of operation, thus in turn increases interference with neighboring operating bands. The frequency reconfigura‐ ble planar quasi-Yagi antennas (Qin et al. 2010) are also unsuitable for its complex feeding structure. "

    ABSTRACT: This chapter presents a comprehensive review of RFID technology concerning the pros pects of directional especially forward directional antennas and propagation for multiband operation. The technical considerations of directional antenna parameters are alsodiscussed in details in order to provide a complete realization of the parameters in pragmatic approach to the directional antenna designing process, which primarily includes scattering parameters and radiation characteristics. The antenna literature is also critically overviewed to identify the possible solutions of the directional antennas to utilize in single and multi-band handheld RFID reader operation. However, it has been seen that these techniques can be combined to enhance the directional antennas with wider bandwidths and higher gain. Last but not least, the possibilities of forward-directional antennas which spectacularly use the surface wave for the radiation will be explored, and the difference with the conventional directional antennas with them will be discussed.

A printed dipole [8] with etched rectangle apertures on the surface is reported to have dual-band characteristics; but it suffers mostly in the consistency of the radiation patterns. "

    ABSTRACT: Radio frequency identification (RFID) excelled in automatic identification and data collection industry through its speed, agility, and endurance. In this letter, an improved uniplanar antenna for handheld RFID reader applications covering free ISM bands of 2.45 and 5.8 GHz is presented. The antenna is composed of a microstrip feeding line, two unsymmetrical ground planes, and a folded strip with a small top branch. The folded strips generate radiations in resonances and the ground, which act as reflectors, force the radiation in the endfire direction. The impedance matching and bandwidth of the antenna is improved by inserting optimized triangular periodic open-end stub (POES) cells on the top edge of the coplanar ground. A good impedance bandwidth of 320 MHz is achieved in measurement (from 2.35 to 2.67 GHz for the lower band), while the upper band covers 310 MHz (from 5.60 to 5.91 GHz). Also, good polarization purity, front-to-back ratio, and gain are found, which makes the antenna a strong candidate for compact handheld RFID reader applications.
