“…According to statistics, more than 80% mobile data traffic is originated in the indoor environments, for instance, commercial buildings and airports. Thus, the indoor distributed antenna systems (IDAS) which are employed to provide wireless communication coverage in high-traffic indoor areas are becoming more and more important [1,2]. An IDAS is a network of compact wideband antennas which connected to a common source via coaxial-cables to enhance the coverage performance.…”

Abstract-A low-profile dual-polarized omnidirectional antenna with an overall height of 80 mm is presented in this paper for broadband indoor distributed antenna system (IDAS). The proposed antenna consists of an improved discone antenna for vertical polarization (VP) and a printed dipole array with five pairs of dipoles for horizontal polarization (HP). The VP element is a combination of three radiation patches, a cone-shaped feeding structure, a circular shorted loading patch and a coupling ring. By loading the shorted patch and coupling ring over the top and at the bottom of the radiation patches, the bandwidth for VP is significantly enlarged while the antenna height is reduced. Simulated and measured results indicate that the operating bands of 0.86-5.62 GHz for VP and 1.62-2.71 for HP are realized. Omnidirectional radiation patterns in horizontal plane for HP and VP, good port isolation of greater than 26 dB, low cross-polarization level, and stable gain (2.6-5.6 dBi for VP and 2.8-4.2 dBi for HP) are achieved during the operating bands, which demonstrate the proposed antenna can be widely used for broadband IDAS.

“…Therefore, the study of broadband miniaturization of dual-polarized antennas has become a research hot spot. In essence, the general methods of miniaturization are to take a dielectric substrate with a high dielectric constant [8], extend path of flowing [9,10] and to introduce reactance elements [11] or shorting probes [12]. But the effect of these methods on miniaturization of dual-polarized dipole antennas is not obvious.…”

Abstract-Artificial magnetic conductor (AMC) is a periodic structure with in-phase reflection, which can be used in dual-polarization dipole antenna to reduce profile height. In this study, a low-profile dual-polarized dipole antenna with an AMC reflector is proposed by improving the AMC structure. The antenna consists of a pair of orthogonal planar dipoles with U-shaped slots, two T-shaped feeding lines, and an AMC reflector. The overall height is 0.132λ 2.2 GHz . Experimental results show that the proposed antenna has a wider bandwidth than other antennas of the same type. The impedance bandwidth of this antenna is 52% (1.65 GHz to 2.81 GHz), and the proposed antenna also has the advantages of low profile, high port isolation (< −30 dB), and low cross polarization (< −27 dB). These features can meet the current needs of the telecommunications industry.

“…However, the gain of the antenna is only 2.6 dBi, which is not high enough. In [8], [9], the bandwidths of the antennas are significantly improved. However, the gains of the antenna are not high enough (<4 dBi).…”

A wideband， high gain， low cross-polarization circular patch antenna with linear polarization and monopole like radiation pattern is proposed for wireless communication systems. The impedance bandwidth (|S 11 |< -10 dB) of 36.5% (4.25-6.15 GHz) is achieved at the central frequency of 5.20 GHz. The simulated and measured peak gains are 9.7 dBi and 9.1 dBi, respectively. A good agreement is achieved between the simulated and measured results.
