“…After that, the shorted patch antenna (SPA) instead of the traditional MPA was alternatively used and designed, and a slot was cut at the minimum electric field of its higher-order modes for simultaneous bandwidth improvement (33.3%) and size reduction [29]. Recently, the MMR design concept was developed for wideband MPAs by further improving the feeding scheme [30]- [32]. Apart from patch antennas, the MMR technique could be alternatively used for other types of wideband antennas.…”

During the past several decades, the multimode resonator (MMR) technique has been extensively investigated and widely used, with successful exploration of a variety of high-performance patch antennas, slot antennas, dielectric resonant antennas, dipole antennas, and so on. In this review paper, we summarize the research milestones for these MMR antennas worldwide as one of the most contributive research teams in this field. First, the basic working principles of the MMR technique are clearly illustrated and studied, including mode excitation, mode suppression, impedance performance improvement, and radiation performance improvement. Next, the research topics regarding impedance performance enhancement, i.e., widebandwidth operation, multibandwidth operation, and mutual coupling reduction, based on the MMR method are intensively described. After that, the relevant works on radiation performance enhancement, i.e., high-gain, wide-beamwidth, multibeam, multipolarization, low-cross-polarization, filtering-response, and leaky-wave antennas, based on the MMR method are extensively illustrated. By using this technique, several ideas about operating frequency reallocation, electric-field null control, radiation pattern reshaping, and efficiency null generation of the antennas are proposed and demonstrated by our team for the first time. In addition, the application of the MMR technique for wireless communication systems is introduced and presented, such as implant communication, wireless power transfer, and multiple-input multiple-output communication. With these arrangements, exploration and reporting of more interesting and useful MMR design methods can be anticipated in the future.

“…The staggered gap‐coupled design discussed in Yoo et al 1 has lower impedance BW, and the wideband design presented in Cao et al 2 employs parasitic shorted patches. The shorted gap‐coupled design presented in Kumari et al 3 requires larger patch size. Initially reported wider BW slot cut configurations either require a larger patch size 4 or offers lower impedance BW 5 .…”

“…To realize multiple modes, techniques like gap-coupled patches, modified patch shapes, resonant slot, and the slot-cut ground plane designs, have been reported. [1][2][3][4][5][6][7][8][9][10][11][12] However, while offering wider BW, none of these techniques gives a reduction in the patch resonance frequency, and thus its area. In the present paper, simple wideband configurations of proximity-fed rectangular MSA (RMSA) and circular MSA (CMSA) by employing H-shape, C-shape, and W-shape ground plane profiles are presented.…”

Proximity‐fed compact wideband rectangular and circular microstrip antennas by employing H‐shape, C‐shape, and W‐shape ground plane profiles are proposed. Optimum results are obtained in rectangular microstrip antenna using H‐shape ground plane. Against the conventional ground plane, it gives 16% bandwidth improvement, supported by 17.29% and 31% reduction in resonant mode frequency and patch area, respectively. The proposed design exhibits a broadside pattern with a gain of 6.1 dBi and can find applications in GSM 900 band.

“…In contrast to the case of using orthogonal polarisation, obtaining good isolation will be more complicated if the same polarisation for the TX and RX must be preserved. Recently, some works on the co-linearly polarised (co-LP) IBFD antenna have been proposed [9], [10], [11], [12], [13], [14], [15], [16], [17], [18]. Utilising the decoupling resonator is a common method to improve the isolation between the TX and RX [9], [10], [11], [12].…”

A dual-linearly polarised (DLP) magneto-electric (ME) dipole antenna is proposed for the inband full-duplex (IBFD) application. It is formed by ME dipoles with a shared central part, giving a compact and symmetrical antenna structure. It has four isolated channels, two for dual-LP transmitting (TX) and the other two for dual-LP receiving (RX). Due to the symmetrical structure, it can provide similar radiation patterns for both the TX and RX ports. Good isolation between any two of all four ports is obtained over a wide frequency range by modifying the antenna structure without introducing any additional complex feeding structures. To validate the proposed antenna, a prototype was fabricated and measured. The measured isolation of any two of four ports is better than 20.9 dB over the wide operating frequency band from 1.90 to 2.75 GHz (36.6%). The measured realised gain in the broadside direction and the measured radiation pattern remain stable in the whole operating frequency band and are similar for the different ports.INDEX TERMS Dual-linearly polarised (DLP), in-band full-duplex (IBFD) antenna, magneto-electric (ME) dipole antenna, wideband.
