“…Techniques involving coupled feeding, multiple resonators, slots on radiating patches or ground planes, and metamaterials have been proposed to increase patch antennas' bandwidth. The antennas achieved 41% and 54% of bandwidths by using L‐shaped probes 1,2 . U‐shaped slots on radiating patches produced extra resonances and expanded the bandwidths to be over 68% for the antennas 3,4 .…”

Radar detection and imaging systems need ultra-wideband, high-gain antennas to improve depth resolution and detection range. This paper proposes an ultra-wideband high gain differential patch antenna having a peak gain of 12.9 dBi and an average gain of 11.3 dBi in the bandwidth from 7.2 and 26 GHz. Two sleeves are added around the feeding probes to attain ultrawideband impedance matching that is explained with an equivalent circuit. A hexagonal cavity with two M-shaped cutouts improves the gain in the broadside direction by redistributing the current and reshaping the antenna's radiation patterns at different frequencies. The antenna's measured S-parameter validates the design and confirms it has an ultra-wide bandwidth.The ultra-wide bandwidth along with the high gain values make the antenna a promising candidate for high-resolution radar systems.

“…In the past decades, two categories of dual-polarized antennas have been mainly developed and employed for communication purposes: dual-polarized patch antennas [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] and dual-polarized dipole antennas [17][18][19][20][21][22][23][24][25][26][27][28]. Dual-polarized patch antennas have become notable candidates for compact systems due to their low-profile specifications.…”

“…Hence, the above-mentioned studies suggest that increasing bandwidth would lead to an increase in the profile. Recently, a coplanar L-strip fed patch antenna in [10] was developed. Compared with traditional L-probe feedings [4], the horizontal feeding line of the L-strip is printed on the same plane as the patch.…”

This paper presents a low-profile wideband, dual-polarized patch antenna using differential-paired, multi-mode arms. By employing the arrow-shaped, differential-paired arms, three modes of them are excited simultaneously, leading to a broad bandwidth. The shorting pins are uniquely inserted at the wings of the arms to obtain stable radiation patterns. Then, two pairs of arms are structured like the dipoles and a dual-polarized antenna is designed. In addition, by employing coplanar coupling feeding structures, a good wideband impedance matching is also achieved without increasing the height. For demonstration, a wideband dual-polarized patch antenna is designed and measured. Benefitting from the advantages of the multi-mode patch and symmetrical structure as a dipole antenna, the proposed dual-polarized antenna operates between 2.10–3.95 GHz, possessing a 10-dB impedance bandwidth of 61%, a profile of 0.1λ0, an average gain of 7.31 dBi, and stable radiation patterns.
