“…Printed dipole antenna provides a triple-band operation with total volume of 0.477λ 0 × 0.528λ 0 × 0.063λ 0 [10]. A horizontally polarized omnidirectional planar antenna which consists of four printed arc dipoles is developed with the diameter of 0.556λ 0 [11]. A dual-band printed dipole antenna is designed by combining a rectangular and two L-shaped radiating elements [12].…”

Abstract-A compact multiband omnidirectional antenna for the reception of GNSS signals on artillery projectiles is designed in this paper. The proposed antenna consists of a metallic cone comprising a T-shaped monopole. It exhibits a broad bandwidth from 1.22 GHz to 1.28 GHz and from 1.44 GHz to 1.75 GHz, covering GPS L1, Galileo E2-L1-E1, GLONASS G1 and G2, CNSS B1 and B3. Measured results show that an omnidirectional radiation pattern is achieved, and the non-circularity in the azimuthal plane (xy-plane) is less than 2 dB for all the desired bands. Then the measured 6 dB beamwidth is about 110 • in the presence of a finite 20 millimeters (mm) radius ground plane. Such an antenna has the potential to be easily used for small artillery projectiles.

“…A planar antenna, consisting of four dipoles on a circular substrate, was proposed in [7], and its bandwidth is from 2.3 GHz to 2.7 GHz. A printed loop antenna, using periodical capacitive loading and a parallel stripline as an impedance transformer and covering the frequency range of 2.17-2.97 GHz, was proposed in [8] and a HPOA for base stations covering 1.67-2.35 GHz in [9]. So far, no reported HPOA can provide adequate bandwidth to meet the requirement for 4G LTE applications.…”

Abstract-A novel wideband horizontally polarized omnidirectional antenna (HPOA) with an electrical conductor reflector is proposed for the 4th generation (4G) Long Term Evolution (LTE) applications. The proposed antenna consists of four pairs of printed dipoles distributed on the front and back of the substrate, and a star-shape patch integrated with stepped parallel strip lines constitutes a balun for the unbalance-balance transition from the coax feeding to the antenna. Both simulated and measured reflection coefficients (S 11 ) demonstrate a wide −10 dB impedance bandwidth of 39.6%, from 1.82 to 2.72 GHz. This band covers PCS, UMTS, LTE 2300, LTE 2500, WLAN and Bluetooth bands. The presented antenna has a peak gain of 3.2 and 4.0 dBi at 1.95 and 2.48 GHz, respectively, and an omnidirectional radiation pattern in E-plane. HPOA may be suitable for ceiling-mounted indoor 4G applications.

“…However, the VP (vertical polarization) of the propagating electromagnetic wave changes significantly with complicated multiple reflections or scatterings [9]. In [10], a horizontal polarized omnidirectional antenna array with 8 elements is proposed. Its bandwidth is 34% and its peak gain is 8 dBi.…”

Abstract-A high gain wideband antenna array with an omnidirectional radiation pattern is presented for base station. The antenna array is composed of four elements and a circular four-way power divider. The proposed planar antenna element consists of four pairs of arc dipoles and a balun, which can achieve a better impedance match and a wider frequency range. Furthermore, the conductor ground of the power divider with a larger size than the element is placed under the four antennas, which can also enhance the peak gain. The antenna array is simulated, fabricated and measured. The measurement results show that the proposed antenna array can achieve a bandwidth from 1.62 GHz to 2.43 GHz or a relative bandwidth of 39.4%. The antenna array has a peak gain of 6.4-7.2 dBi in the work band and obtains a radiation efficiency of 88%. The simulated and measured results show that the proposed antenna array is a good candidate as a base station antenna for GSM, PCS, and UMTS applications.
