“…Due to dipole 2 and the strong coupling between the crossed dipoles, the excited currents on dipole 1 flow mainly along the edges of the square metal arms of the dipole, which is useful to extend the flowing path of the current and then reduce the size of the antenna. The strong coupling can also extend the bandwidth of the antenna, and the principle is similar to that in [10].…”

“…Many researchers have made a lot of efforts on the development of dual-polarized antennas [2][3][4][5][6][7][8][9][10][11][12][13] and broadband base station antennas [8][9][10]. The dual-band dual-polarized antenna that proposed in [6] was formed by arc-probe-fed annular ring element and pairs of cross microstrip dipoles nested together, and achieved an impedance bandwidths of 17.4% (806 ∼ 960 MHz) for VSWR < 2 in the lower band and 23.7% (1710 ∼ 2170 MHz) in the upper band, respectively.…”

Abstract-A compact dual-band dual-polarized antenna is proposed in this paper. The two pair dipoles with strong end coupling are used for the lower frequency band, and cross-placed patch dipoles are used for the upper frequency band. The ends of the dipoles for lower frequency band are bent to increase the coupling between adjacent dipoles, which can benefit the compactness and bandwidth of the antenna. Breaches are introduced at the ends of the dipoles of the upper band, which also benefit the compactness and matching of the antenna. An antenna prototype was fabricated and measured. The measured results show that the antenna can cover from 790 MHz to 960 MHz (19.4%) for lower band and from 1710 MHz to 2170 MHz (23.7%) for upper band with VSWR < 1.5. It is expected to be a good candidate design for base station antennas.

Abstract-Current phones include more metal than earlier, which deteriorates the performance of antennas. This paper presents the first complete antenna set designed for a modern handset with a full metal back cover. 4G, Wi-Fi, and GPS antennas are integrated into the metallic side frame of the device in a realistic model. The designed antennas are either capacitive coupling elements with reactive loads or slot antennas. Fixed matching circuits are used to improve total efficiency. The passive implementation enables the use of carrier aggregation (CA) to increase the data rates, and includes also the multipleinput multiple-output (MIMO) operation for 4G and Wi-Fi. The designed antennas cover frequency bands 704-960 MHz, 1.56-1.61 GHz, 1.71-2.69 GHz, 2.4-2.484 GHz, and 5.15-5.875 GHz, producing in measurements a good agreement with simulation results.

“…Another popular dual‐polarized antenna is crossed dipole antenna and several broadband crossdipoles are presented in References . Adopting artificial magnetic conductor (AMC) as a reflector, the antenna in Reference achieves a low profile, but its performance of isolation and crosspolarization is not well enough.…”

A dual‐polarized antenna that simultaneously achieves low profile, low crosspolarization, and high isolation is presented in this article. Our research indicates that the irregular currents on the artificial magnetic conductor (AMC) surface in our design can lead to an extra coupling. Because short pins can regularize the surface currents on the AMC surface and work as a balun, our antenna can achieve low crosspolarization and high port isolation. The proposed antenna achieves a profile height of 0.08 λ0 (λ0 represents the wavelength in free space at 3.4 GHz) and 23.5% (3.0‐3.8 GHz) relative bandwidth. The port isolation of the presented antenna is higher than 37 dB and the normalized crosspolarization is lower than −35 dB. The proposed antenna is suitable for the fifth generation communication systems.
