“…For instance, we can find compact designs for antennas with polarization diversity using the same radiation pattern as in [8], but also with different radiation patterns for each polarization [17]. Both cases refer to two-port antennas, but also a four-port antenna corresponding to two radiation patterns, each of them with two polarizations, can be implemented if desired as in [16], but assuming a more complicated and bigger antenna.…”

“…These antennas can be easily implemented as combinations of dipoles and shaped ring slots [8]. To further reduce the total antenna size, we also propose to use a single multimode antenna with four ports providing two different radiation patterns with the two polarizations each (Scenario III) [16]. These results are included in Fig.…”

Abstract-Multiple-input-multiple-output (MIMO) schemes designed to increase channel capacity face strong limitations when a large number of antennas must be deployed in a terminal due to size constrains. This letter discusses how the different combinations of the three types of diversities-namely spatial, radiation pattern, and polarization diversity-can be used to get an improved capacity in compact terminals. The study compares realistic combinations that overcome the need for a large number of radiating elements in the user terminal.

“…Dipole antennas [2], patch antennas [3,4], slot antennas [5][6][7][8], and loop antennas [9][10][11] have been chosen amongst typical radiators for such systems. Most of the ordinary dual-polarized antennas are realized using the same radiators fed by orthogonal feeds [12], otherwise fed by complementary feeds [13]. However, these types of dual-polarized antennas have the disadvantages of limited design flexibility and low port isolation.…”

Abstract-Based on the theory of Babinet's principle, a type of dual-polarized antenna working on C band is designed using complementary structures. The structures comprise a wire loop antenna and a slot loop antenna, which is complemented and fed by coaxial lines. A ground is placed to improve the front-to-back ratio of the antenna. The performance of the antenna is hereinafter studied experimentally, followed by the implementation of a prototype antenna. Its stable and symmetric radiation patterns are obtained within the frequency of 4.9 GHz∼5.1 GHz, and the port isolation is less than −24 dB. The measured results coincide with the simulated ones. This explains the feasibility of the proposed dual-polarized antenna.

“…Moreover, polarization-diversity is preferred over spatial-diversity for it leads to a lower installation cost. This is because the polarization-diversity usually requires one antenna, while the spatial-diversity usually requires two antennas [5].…”

Abstract-A novel log-periodic dipole antenna for dual-polarized radar systems is presented. The proposed antenna employs meander line technology and matched loads. The simulated and measured results show that the −6 dB reflection coefficient bandwidth of the dual-polarized antenna covers the desired band of 2-8 GHz and the port isolation is higher than 32 dB, along with −20 dB cross-polarization discrimination for both E-and H-planes.
