A broadband dual‐polarised antenna with L‐shaped strips for long‐term evolution (LTE)/5th generation mobile networks (5G) is proposed in this article. Based on the principle of multi‐mode resonance, wide bandwidth is achieved with L‐shaped strips and H‐shaped strips. The metal strips and dipoles are printed on the same substrate, which also contributes to antenna miniaturisation. The short pins are designed for impedance matching and improving isolation. The metal reflector is designed to control beamwidth and increase gain. A prototype was fabricated using an easy Printed Circuit Board technique to verify the proposed design. Low‐profile of 0.2λ0 (λ0 is the free‐space wavelength at the centre frequency) is achieved. The measured results show that the relative bandwidth is 74% (2.3–5.0 GHz) at Voltage Standing Wave Ratio <1.8 while the isolation is more than 24 dB covering the LTE/5G modern band. In addition, the in‐band average gain is 9 dBi.

“…D ual-polarized antennas offer a pair of communication channels with the same operating frequency but orthogonal polarization, enabling frequency reuse and polarization diversity. They have significant advantages such as high signal transmission capacity and strong anti-multipath fading [1][2][3][4][5][6], making them widely used in mobile communication systems. With the rapid development of modern RF front-end technology, there is a growing demand for dual-polarized antenna integration with increasingly limited space available for antenna design.…”

In this paper, a compact dual-polarized antenna with wide band and high isolation is proposed, which can be applied to the 5G WiFi frequency band. The antenna is composed of 2 × 2 arrayed patches and two orthogonal L-shaped probe structures with reduced middle patch width and loaded U-shaped slots. The proposed antenna achieves a compact size by eliminating the need for a complex feeding network, instead utilizing only two closely spaced L-shaped probes for feeding. The antenna's radiation modes excited by two ports are orthogonal in polarization direction, and each port can excite two linearly polarized radiation modes respectively within the operating frequency band, thereby achieving dual-linear polarization and wideband performance. The antenna is analyzed and designed using characteristic mode analysis (CMA). By reducing the patch middle width and loading U-shaped slots on the L-shaped probe of the antenna, the suppression of high-order modes, improvement of isolation, and reduction of cross-polarization levels are achieved. The size of the antenna is 0.54λ0 × 0.54λ0 × 0.068λ0 (λ0 is the free-space wavelength of central frequency). The measured bandwidth is 23.5% (4.73 GHz-5.99 GHz) with |S11| < −10 dB, |S21| < −27.9 dB, boresight gain of 4.8 dBi-6.2 dBi, and cross-polarization levels better than −23 dB.

A multi-mode wideband antenna based on multi-mode resonator is proposed with stable radiation pattern, which is composed of two metal radiators, two parasitic resonators, two shorted patches fed by the U-shaped feedline and a box-shaped reflector. A prototype of the proposed antenna is designed, fabricated and tested. Measured results show that the antenna achieves an impedance bandwidth of 37.5% (0.67-0.98 GHz) for |S11|<-15 dB, a half-power beam width (HPBW) of 67.5±2.4 degree at H-plane (horizontal plane) and a gain of 7.9±0.4 dBi. Furthermore, the XPD is more than 15 dB at 0° and at least 11.2 dB within ±60°at H-plane, respectively. The proposed antenna can be used in modern communication system for LTE700/GSM850/GSM900.
