“…With the development of mobile communication technology, the different mobile communication systems have different communication frequencies. Now at the present stage, in the 2G communication system (CDMA800 and GSM900 and GSM1800 and GSM1900), its working frequencies are from 824 MHz to 960 MHz and from 1710 MHz to 1926 MHz; the work frequency of 3G system (TDS-CDMA, WCDMA, and CDMA 2000) is from 1880 MHz to 2170 MHz, with the comprehensive promotion of LTE (4G) technology, the frequency of LTE2300/LTE2500 becomes the new demand in the 4G communication system, and its working frequency band is from 2300 MHz to 2400 MHz/2500 MHz and 2690 MHz [1][2][3][4].…”

A design of dual broadband antenna is proposed in this paper; it consists of one low frequency unit and two high frequency units. The low frequency unit consists of a pair of printing vibrators; the high frequency unit consists of a pair of printing oscillators, which is bent at its end, and high frequency unit and low frequency unit are set on the same dielectric substrate. Through adding a parasitic unit on antenna, it can enhance frequency bandwidth without affecting the bandwidth. In the high frequency unit, it adopts gap-coupled microstrip line feeding method in order to get enough bandwidth. Through the test of dual broadband antenna, it can be found that, in the low frequency part, the antenna covers 20% bandwidth of the total bandwidth, and it covers the frequency from 800 MHz to 980 MHz. In the high frequency, the antenna covers 60% of total bandwidth and its frequency is from 1540 MHz to 2860 MHz, so the designed antenna can satisfy the frequency requirements of 2G/3G/LTE (4G) communication system.

“…Patch and dipole antennas have also been used for many years to develop broadband antennas for base stations [6]. The patch antenna in [7] achieved a bandwidth of 30% for S 11 ≤ −10 dB, while the bowtie patch antenna in [8] achieved 45% impedance bandwidth. The printed dipoles in [9,10] achieved 40 and 50% bandwidth for S 11 ≤ −10 dB, respectively.…”

“…The proposed antenna has a slightly higher gain when compared with the single elements (1 × 1 array) of the omnidirectional dipole antennas in [1,5,12] with approximately similar sizes. The proposed antenna has omnidirectional radiation and smaller in size when compared with the directional dipoles in [7][8][9]11], although the proposed antenna has a lower gain compared to these antennas.…”

This study presents an omnidirectional dipole antenna with wideband and low gain variation in the horizontal plane. The antenna is made up of two driven dipoles and two parasitic dipoles placed symmetrically on both sides of a central ground plane. The driven dipole is made up of two planar arms printed on both sides of the substrate. Two small slits on both sides of the driven dipole, a large centrally placed slit in the driven dipole, extensions on both sides of the driven dipole with different dimensions, and parasitic dipoles are introduced to greatly enhance the bandwidth and also attain a low gain variation. The fabricated antenna achieves a wide impedance bandwidth of 105.5% (1.36–4.4 GHz) for S11 ≤ −10 dB, and an average gain of 4.14 dBi with a low gain variation of 2 dB. The antenna may find applications in 2G/3G/LTE frequency bands.

“…Therefore, the pseudo-PMC effect of HIS is defined as bandgap range of 0 ∘ ± 90 ∘ . Using HIS as a reflector, a lot of low-profile antennas have been reported [11][12][13][14][15][16]. A planar folded dipole on via-less dog bone-shaped HIS array is presented in [11], achieving a measured impedance bandwidth of 6% and a boresight gain of 6.4 dBi.…”

“…By inserting via only at reflector edges, while the center part is via-less, a hybrid HIS is proposed in [13], which significantly alleviates antenna beam distortion and reduces side lobe level. Low-profile bowtie antennas are published in [14][15][16] with wide bandwidth and small physical thickness. However, the electrical thickness is still large.…”

This paper proposes minimized low-profile wideband antenna by employing high impedance surface (HIS), for wireless application scenarios at radio frequency, microwave, and even terahertz. To validate this concept with low cost and easy measurement, two prototypes at radio frequency are fabricated and tested. Firstly, antenna with dielectric-substrate reflector is proposed and analyzed and 4 × 6 HIS array is employed to minimize the antenna size to 0.57 × 0.86 × 0.078 , while maintaining antenna performances such as bandwidth, gain, and directive radiation. Secondly, a substrate-less HIS is proposed to improve the antenna bandwidth from 36% to 52% and also reduces the antenna weight by 72%.
