“…In order to triumph wideband operation with compact outline Xiao et al [8] excited the antenna's TM10 and TM01 modes simultaneously. Likewise, several other authors were successful in getting an impedance bandwidth above 12% by experimenting with the resonant modes [9][10][11][12][13]. It is evident from the results presented in [14,15] that with a proper feeding arrangement, the operating bandwidth can be extended above 28%.…”

The extending applications for mobile computing have experienced immense progress over the previous decade. However, this has ultimately influenced the shortage of bandwidth. Therefore, to fulfill the consumers' demand, inexpensive antennas need to be uniquely designed for the next/fifth generation (5G) frequency spectrum. Consequently, this paper presents a novel antenna composed of inductors (L) or capacitors (C) on an air-substrate. Zinc (Zn) and copper (Cu) materials are utilized to fabricate the lumped LC resonator prototype. The effects of antenna's and substrate's thickness on resonant frequency or bandwidth have been studied. The finalized configuration engaged 1113 sq. mm area and operated at 28 GHz with approximately 3 GHz bandwidth. At resonant frequency, the system demonstrates peak gain and efficiency values of 10.6 dBi and 91%, respectively. The core objective of this paper is to report an antenna featuring simple and economical design along with premium results for 5G mobile terminals.

“…As described in the previous section, the antenna shown in Figure 1 had a wideband circular polarization; however, it also had a small impedance bandwidth. This can be addressed by employing impedance bandwidth enhancement techniques [26][27][28][29][30]. For example, the dual resonance method was used in references [27][28][29][30] to improve the impedance bandwidth of patch antennas.…”

In this paper, a wideband, circularly polarized patch antenna is proposed that leverages the unidirectional resonant modes of a circular patch mounted on top of a grounded dielectric‐ferrite substrate. The proposed antenna is fed via the proximity coupling method and several parasitically coupled patches are placed on a dielectric superstrate to enhance the impedance bandwidth of the antenna. The resonant modes of the structure rotate only in the clockwise or counter clockwise directions. In the frequency range where the effective permeability of the ferrite layer is negative, the resonance frequencies of these modes differ significantly, which produces a large axial ratio (AR) bandwidth. For the proposed antenna, the numerical results show the 10 dB impedance bandwidth to be around 44% and the 3 dB axial ratio bandwidth to be higher than 64%.

“…In Reference 12, a DMPA under the operation of TM 10 and TM 30 mode is proposed, and the bandwidth reached 13%. Similarly, a DMPA with a bandwidth of 14.8% under TM 12 and TM 30 mode is proposed in Reference 13. However, since the resonant frequencies of dominant modes are far from those of high-order modes, it is challenging to integrate three or more modes into one operation band.…”

A compact broadband differential‐fed microstrip patch antenna with 5.8 GHz WLAN band‐notched under quad‐mode resonance is proposed in this article. The antenna consists of two hybrid shape radiation patches and a pair of capacitances loaded loop (CLL) resonators. The broadband performance is achieved by integrating TM10 and TM01 radiation modes of rectangular patches and TM1,0,−1 radiation mode of triangular patches. Then these three radiation modes are adjusted close to each other to form a wide operation band. After that, with the loading of CLL resonators, a nonradiative resonant mode is introduced. Thus, the low‐frequency band of the proposed antenna can be further expanded, and a frequency notch point is introduced in 5.8 GHz WLAN band. Finally, the proposed antenna is fabricated and measured. The measured impedance bandwidth is about 43.5% (5.93‐9.23 GHz) while keeping a compact structure without any air gaps. Additionally, the broadside gain is varied from 4 to 6 dBi with a notch point at 5.8 GHz.
