  • Impact of directional antennas on contention based MAC protocols in ad hoc networks

    Recently, ad hoc networks using directional antennas have been actively studied because they can achieve many advantages such as increased spatial reuse, reduced interference and energy saving, resulting in performance improvement as compared to omnidirectional antennas. In this paper, we study the impact of directional antennas on contention based MAC (Medium Access Control) protocols in ad hoc networks. The contention based MAC protocols for ad hoc networks with directional antennas are reviewed and qualitatively compared and, then, the superiority of directional antennas to omnidirectional ones in ad hoc networks with contention based MAC is evaluated and quantitatively compared via simulation.

  • Analysis and Design of a 45 $^{\circ}$ Slant-Polarized Omnidirectional Antenna

    A 45° slant-polarized omnidirectional antenna is proposed for mobile communication base stations. The proposed antenna consists of four printed crossed-dipole elements which are rolled up into a cylinder for omnidirectional radiation. Each crossed-dipole element is composed of a horizontal dipole and a vertical dipole. The 45° slant polarization is achieved by adjusting the lengths of the horizontal and vertical dipoles. A broadband feeding network consisting of four broadband baluns and an impedance matching circuit is introduced to feed the four crossed-dipole elements. Experimental results show that the omnidirectionality or gain variation in the horizontal plane is less than 1 dB while the cross-polarization level is below -15 dB over a bandwidth of 15% (1.9-2.2 GHz). The 45° slant-polarized omnidirectional antenna has a bandwidth of 22% (1.75-2.18 GHz) for 15-dB return loss. Theoretical analysis and design procedure are presented.

  • Neighbor discovery algorithms in directional antenna based synchronous and asynchronous wireless ad hoc networks

    The performance of wireless systems could be significantly improved by directional antennas with highly efficient MAC layers and other control protocols and algorithms. One such critical algorithm is neighbor discovery, which establishes links between adjacent neighboring nodes in the network. In this article, we first study the slotted synchronous system and propose a novel neighbor discovery algorithm to address the high collision problem caused by high node density. We then evaluate the performance of neighbor discovery algorithms and extend the results to asynchronous systems. Simulation results show that for the synchronous system, our algorithm consistently shortens the required time for the whole discovery process from that in previous works; for an asynchronous system, our algorithm sheds insight on how to select design parameters.

  • Wideband Ceiling-Mount Omnidirectional Antenna for Indoor Distributed Antenna Systems

    A wideband omnidirectional antenna is presented in this letter. The proposed antenna consists of three radiators over a ground plane, a monopole composed of three patches fed by a coaxial line, a coupling patch with three shorting legs above the monopole to extend the lowest frequencies of operation, and a top-loading disk located on the top of the coupling patch for further decreasing the lowest frequencies of operation. An enhanced impedance bandwidth of 9.23:1 ranging from 650 MHz to 6 GHz with 13.9 dB (for SWR ≤ 1.5) is achieved. The antenna meets network operator's requirements for cellular bands and has good radiation efficiency in the WiFi bands. The proposed antenna can be widely used in indoor distributed antenna systems, such as 3G, 4G LTE, and WiFi (2.4 and 5.8 GHz) bands. The antenna is simulated by ANSYS HFSS and measured in a microwave anechoic chamber. The simulated and measured results show good agreement.

The antenna consists of a top-loaded monopole for vertically polarized working state (VP), a circular loop for horizontally polarized working state (HP). The circularly polarized working state (CP) is achieved by exciting the monopole and the loop simultaneously with different phases. It is shown that the bandwidth overlapped for VP, HP, and CP is about 25% (1.7-2.2 GHz) with good omnidirectional patterns.

  • A Multiband Dual-Polarized Omnidirectional Antenna for 2G/3G/LTE Applications

    A multiband dual-polarized omnidirectional antenna for 2G/3G/Long Term Evolution (LTE) mobile communications is proposed in this letter, which consists of horizontal polarization (HP) and vertical polarization (VP) element with separate feeds. The VP element consists of three polygonal radiation patches with three equally spaced legs shorted to the ground plane. The HP element consists of three wideband slot loop structures, which is nested on the top of the VP element. Three slot loop structures provide a 360° coverage for HP and enhance its bandwidth. Both the simulated and measured results indicate that the frequency bands of 1650-2900 MHz for HP and 780-2700 MHz for VP can be achieved. The reflection of VP improves the gain of the HP element at least 1 dBi after nesting. The gain of HP element is more than 3 dBi for LTE, and the gain of VP element is more than 5 dBi in the LTE band and 1.5 dBi in the 2G band. Port isolation larger than 30 dB and low-gain variation levels are also obtained. The proposed antenna can be applied in mobile communications.

  • Broadband dual-polarized omnidirectional antennas

Both dual- polarized omnidirectional antennas have a bandwidth of about 30%. Good omnidirectional radiation patterns are obtained for both polarizations. An eight-element antenna array for each of the broadband dual-polarized omnidirectional antennas is developed.

The array are formed by two stacked biconical antenna elements fed parallel through a balun, and each element can produce an omnidirectional gain of around 9.5dBi. The measured ™10-dB impedance bandwidth of the antenna is 26.2-30.2GHz. Within the bandwidth, the antenna achieves a high measured omnidirectional gain of around 12.5dBi corresponding to about 5°3-dB beamwidth.

  • A Novel Wideband Omnidirectional Circularly Polarized Antenna

    In this paper, a novel wideband omnidirectional circularly polarized (CP) antenna is proposed. The designed antenna consists of the 2×2 dipoles. The 2×2 dipoles are fed with equal amplitude and phase arranged in circles. And the current directions of the two pairs of opposite dipoles are opposite to each other, which generate the omnidirectional CP. The VSWR of proposed antenna is less than 2 within 4.33GHz-5.38GHz, whose relative bandwidth is 21.6%. The 3-dB axial ratio bandwidth is 4.53-5.84GHz (25.3 %). Due to the omnidirectional radiation of the proposed antenna, the antenna can be used in indoor communications and automotive vehicles mounted antenna.

  • Design of A Broadband Vertically Polarized Omnidirectional Array Based on Vivaldi Antenna

    Using eight Vivaldi elements, a wideband omnidirectional array is proposed in this paper. First, in order to achieve roundness radiation pattern of array in horizontal plane, a Fermi Vivaldi antenna is optimized, which can achieve a 3-dB beam width of 45° (±10°) from 5.5GHz to 7.6GHz. Then, the elements in the H-plane with periodic angle of 45° are employed to build the circular array. Finally, the array is fabricated and its performance is evaluated. Measured result shows the designed array can obtain a bandwidth from 5.5 to 7.6GHz for both omnidirectional radiation pattern and S11 ≤ -10 dB. In addition, this array has a potential application for beam switching with smooth angular variation over a 360° range.
