Dual-polarised slot-coupled patch antenna excited by a square ring slot

Differentially Fed Metal Frame Antenna With Common Mode Suppression for Biomedical Smartband Applications

“…In addition to proposing a metal box placed inside, another advantage of this work lies in its method of matching the slot internally. In contrast, if we refer to traditional ring slot proposed in Caso et al (), Ram Krishna and Kumar (), Ramirez and Parron (), and Wong et al (), it can be noticed that all of them are implemented with large ground plane surrounding the excited slot, thereby making them unfit for smartband application where size reduction is of paramount importance. More specifically, the traditional external large ground plane is replaced by thin metal frame in this paper, and the internal metal part is replaced by a metal box which is used to accommodate the electrical components.…”

A Low-Profile, Wideband, Dual-Polarized Patch Dipole With Unidirectional Radiation Patterns

“…Some comparisons between antennas published in [10,[12][13][14][15][16], and the proposed one is made as shown in Table 1. It can be seen that the proposed dual-polarized antenna has some advantages such as lower profile and wider operating frequency band than the works in [12][13][14][15]. Although the proposed antenna has a similar profile to the one in [16], it still demonstrates higher isolation and wider bandwidth.…”

Broadband Vertically/Horizontally Dual-Polarized Antenna for Base Stations

“…In recent years, lots of dual-polarized antennas have been developed for base stations [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Most of dual-polarized antennas consist of a patch [4][5][6][7][8][9][10][11][12][13] or two crossed dipoles [14][15][16][17][18][19]. It is well known that patch antennas and dipole antennas usually have different beam widths in the E-plane and H-plane.…”
