“…Several techniques have been investigated to design multiband DRAs, such as stacked DRAs [8], multiple DRAs [9], hybrid DRAs [10], [19], using the feeding structure to add another band [11] and generation higher order modes [12]- [18]. However, most of these DRAs support either dual band [8][9][10][11][12][13][14][15][16][17], or high frequency ratio [19]. Although [12] and [18] achieve multiband with small frequency ratio, the antenna size is obviously large corresponding to its lowest operating band.…”

“…Single port microstrip antenna with dual polarization characteristics is realized using offset feeding and annular slot, parasitic patch, stacked patch, artificial magnetic conductor, and slot coupled power divider . Recent works have been reportedon realizing single port DBDP antenna using dielectric resonators, but thickness of dielectric radiator is still a major constraint of this technique. Antennas with circular polarization are used for direct wave communication and whereas linear polarized antennas are used for broadcasting in ground wave communication.…”

This document presents a dual band dual polarized coplanar waveguide (CPW) antenna with single port feed. Lower resonating band is circular polarized, while the upper band is linear polarized. A novel concept of realizing dual polarization by suppressing the undesired modes is introduced in this work. Orthogonal Even/Odd modes are excited at lower band and a phase difference of 90° is maintained between them. Hence, circular polarization behavior is realized for lower operating band. For upper band, Odd mode is suppressed by introducing step shaped modifications in the ground plane at left side of the feed line, resulting in linear polarized upper band. Dual band nature of the antenna is confirmed by 10 dB impedance bandwidth extending from 3.91‐5.31 GHz to 7.51‐8.72 GHz. Circular polarized nature of lower band is confirmed by enclosure of lower band by 3 dB axial ratio bandwidth extending from 4.01 to 5.59 GHz. Advantages of proposed antenna involves the use of single port feed for generating dual polarization performance along with compact antenna size.(30 × 30 × 1.6 mm3).

“…There are many studies for dual-band dual-polarised antennas in the last few years [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. There are many methods to achieve a dual-band dual-polarised antenna, such as using high-order modes [2,3], or using different basic modes [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. The antennas in [4][5][6][7][8][9][10][11][12] have two operating frequency bands but only have one polarisation at each band.…”

A wideband dual‐band dual‐polarised patch antenna is proposed here. It consists of a ground that has a cross slot and a rectangle hole, a feeding structure that consists of two π‐shape strips, and a radiating patch that consists of a square loop strip and a small square patch with a cross slot. Two feeding ports are used to generate two orthogonal polarisations. A prototype has been fabricated and measured. The measured −10 dB impedance operating bands of the two ports can cover the bands of 3.59–4.21 GHz and 5.42–6.34 GHz, the relative bandwidth are 15.9% and 15.6%. The measured isolations between the two ports are more than 20 and 15 dB at the lower and higher bands, respectively. The antenna has a good radiation performance at the lower and higher bands.
