“…J. Ha et al obtained a similar behaviour of near-and far-fields from the antenna consisting of metal patches backed by the CSRR(complimentary split ring resonator) [10], which has a decreased size from the RH half-wavelength. As the ZOR antennas, tightly coupled SRRs shorted to the ground and shorted ring coupled circular patch for the MIMO and low-profile monopolar radiation, respectively, were designed [11,12] Whether an antenna has the RH half-wavelength or metamaterial resonance, when it is applied to the repeater, the satellite communication, the elements of base-station antennas and so on, dual-polarization will be needed [13][14][15][16][17]. With the requirement on the compact geometry, when the dual-polarization is decided as a design objective, one radiating body should create 2 different polarizations.…”

“…With the requirement on the compact geometry, when the dual-polarization is decided as a design objective, one radiating body should create 2 different polarizations. There are dual-polarized microstrip patch antennas reported in literatures like [13][14][15][16][17]. Perpendicular line-feeds attached to the ordinary patch were studied for dualpolarization [13].…”

“…Padhi used a multilayered antenna comprising a circular patch on the top and two apertures in the middle layer above the bottom with two line-feeds [16]. ±45 o polarizations are made by 2 arrays of parasitic loads and radiators excited by inverted L-shaped feeds for higher polarization isolation [17].…”

-A novel fully-printed microstrip antenna with negative first resonance and dual polarization is proposed. The radiator is printed on the 1-layer substrate instead of multilayers. The -1st resonance results from a composite right-and left-handed(CRLH) structure that has a circumferentially interlocked gap capacitively coupling a patch with a shorted-ring. This compact antenna is provided with a dual-polarization capability by creating two orthogonal linear polarizations in one body with coaxial feeds. The design is carried out by doing full-wave EM field simulation which is compared with the measurement of the fabricated antenna prototype. The measured results give the gain of 5 dBi and the efficiency of 78% at the -1st resonance mode as the center frequency of a downlink channel of the bandwidth over 20 MHz with 29 dB polarization isolation for mobile communication.

“…Hence, different antennas with a beam switching scheme can be utilized on base station antennas for pattern diversity. Many dual polarization and pattern diversity antennas for cellular base station have been reported in [1][2][3][4][5][6][7][8]. In [5], Wang et al proposed a pair of small and low-profile orthogonal dual-polarization combined antenna for a miniature indoor MIMO base station.…”

“…The measured impedance bandwidths were determined by the VSWR < 2 criterion, which covers 806-960 MHz and 1710-2170 MHz. Likewise in many other studies, the dual polarization was achieved by the combination of printed dipoles, patch elements arrays and spiral antennas, as reported in [1][2][3][4]. The pattern diversity approach was investigated by Tarn et al in [9,10].…”

Abstract-A novel multiband, dual-polarization, beam-switched dual-antenna design, covering some LTE and WLAN bands, has been proposed for indoor base stations. The proposed design consists mainly of dual modified monopole antennas. The horizontal antenna consists of four printed monopole elements, and the control circuit using p-i-n diodes has been implemented for feeding to each monopole element. The vertical monopole antenna beam patterns are controlled by reconfigurable frequency selective reflectors (RFSR) technique. The p-i-n diodes have been utilized for switching mechanism to feed the four RFSR. The measured and simulated results indicate that the antenna system possesses multiband and dual polarization. It has been observed from the simulated and measured reflection coefficients |S 11 | that the presented dual antenna system supports both LTE (1.7-2.1 GHz) and WLAN (2.5 GHz and 5.8 GHz) band frequencies. Moreover, the radiation characteristics show dual-polarization behaviors of the presented antenna system and beam switching states suitable for small cell indoor-base stations.

Design of L-plate proximity fed base station antenna element mustafa murat bilgic ‚ and korkut yeg ' in Wideband microstrip antenna with L-plate capacitively coupled feed structure is designed. The antenna operates in GSM 1800/1900 (1710-1910 and UMTS I (1920-2170 MHz) frequency bands. The antenna has dual slant (+458) polarization with high isolation (.25 dB) between the ports. Measurements of the antenna reveal good performance in terms of impedance match, gain, gain flatness, isolation, half-power beamwidth, cross-polarization level, and front-to-back ratio. The proposed antenna can be used in base station antenna arrays, pico-cell, and femto-cell small-area cellular networks.
