A Broadband $\pm 45^{\circ}$ Dual-Polarized Antenna With Y-Shaped Feeding Lines

A broadband dual‐polarized antenna with chamfers

“…Furthermore, miniaturization is desirable in the antenna array for the element coupling reduction. Dual-polarized antennas have great development in recent years for base station applications [3][4][5][6][7][8][9][10]. However, it is still difficult to achieve wide bandwidth, stable radiation pattern, low cross polarization and compact size simultaneously.…”

“…[1][2][3][4][5][6][7][8][9][10][11][12][14][15][16][17][18][19][20][21][22][23][24][25][26][27] The magneto-electric dipoles (MED) technique, dipoles consisting of an electric pole and a magnetic pole that cause to expand bandwidth, radiation patterns stability, high gain, and low cross polarization. 1,[5][6][7][8]12,13,15,17 Multilayer PCB technique, in this way new frequency bands are created by stimulating resonant modes on the plates, thereby the antenna bandwidth is extended as adjacent multiband. 16,17 The parasitic element technique, which uses it to increase bandwidth or improve radiation indices, such that when a parasitic element is added near the dipole, the dipole resonance length may be shorten.…”

“…2,4,5,7 Coupling techniques, different coupling methods such as L, T, Y, loop, are used in the design of broadband dipole antennas that matching the coupling element to the dipole plates has a direct effect on the coupling value. [2][3][4][5][7][8][9][10][11][12][13][14][15] The non-PCB techniques, these types of antennas are made only of metal sheets with slit that have high power tolerance and mostly used for large area radio coverage. [18][19][20] Cavity reflector techniques, in this method a variety of cavity reflectors are used to improve the antenna gain, directivity, and ratio of front-toback lobes.…”

“…25 The AE45 cross dual-polarized antennas techniques used to reduce multipath fading and increase channel capacity, usually replace to the space diversity systems and occupy a little space. [1][2][3][4][5][6][9][10][11][12][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] Methods of feeding dual-polarized antennas such as direct probe (coaxial cable), side coupling (horizontal and vertical), and feeding by balun (printed and nonprinted) that use balun cause high loss, low efficiency, and complexity of structure. [20][21][22][23][24][25][26] In this article, a dual-polarized antenna is presented in which irregular polygon patches and trapezoidal plates are printed on both sides of the substrate at a AE45 angle and a box-shaped reflector is embedded in the back of the substrate.…”

A low‐profile wideband dual‐polarization patch antenna with antisymmetric feeding network

“…1 The wideband dualpolarization antenna is widely used in mobile communication system and reported in the last article. In the past research, most base station antenna can be divided into two category: one category is the cross-dipole antenna [2][3][4][5][6][7] and the second category is the patch antenna. [8][9][10][11][12][13][14][15][16] The dipole antenna is a classic and the most widely used antenna to date.…”
