“…Patch antennas for multiband operations were also presented [4][5][6][7][8]. Coplanar waveguide antennas (CPW), such as dual-band rhombus slot [9], monopole antenna employing T-shaped quasi-self-complimentary resonators [10], parasitically loaded CPW-fed [11], and planar monopole [12], are also applied to realize multiband operation due to their low cost and omni-directional radiation pattern.…”

“…In this paper, a new design of planar antenna with parasitic strip suitable for MIMO application is presented. Compared to the antennas in [2][3][4][5][6][7][8][9][10][11][12], the proposed antenna in this paper not only achieves triple bands simultaneously but also has a rather simple structure that is easy to fabricate. Meanwhile, the proposed antenna structure also allows for the independent adjustment or tuning of each frequency of interest within certain limits, which is important aspect for manufacturing.…”

A new microstrip slot antenna with parasitic elements has been presented in this paper. The proposed antenna is composed of a microstrip feed line, a ground plane on which some simple slots are etched, and parasitic elements. Simulation results show that the antenna structure allows for the independent adjustment of each frequency. A two-element array configuration of this antenna for MIMO application is investigated as well. For comparison between simulation and measurement result both single and array configurations have been fabricated. The measurement result exhibits good radiation performance in terms of return loss, low mutual coupling, and compactness.

“…Thus, a multi-band CP antenna which can operate both at GPS and CNSS frequency bands is required. With the rapid development of wireless communication systems, multiple frequency bands antennas [6][7][8][9][10] have been developed to meet increasing demand for a modern portable wireless communication standard in a single system. In particular, various types of designs related to multi-band CP antennas have been reported [11][12][13][14][15][16][17][18][19][20][21][22].…”

A novel single-feed tri-band circularly polarized (CP) annular slot antenna is presented. The antenna structure is composed of two nonconcentric annular slots that are fed by an Lshaped series step impedance microstrip line configuration. The proposed antenna is designed to operate at the L 1 and L 2 bands of the global positioning system and the operating band of the compass navigation satellite system. Compared to the most of the previously reported tri-band CP antenna structure, the proposed antenna has low profile, compact size, and easy fabrication on the single-layer PCB. The measured results show that the impedance bandwidths are good for all bands. The axial ratio bandwidth and radiation patterns are also measured at the three resonant frequencies. The proposed compact tri-band CP antenna design is suitable for mounting onto the mobile communication devices and portable positioning systems. IntroductionCircularly polarized (CP) antennas have received much attention for the applications of the wireless communication services such as global and positioning system (GPS) and other wireless communications and sensor systems, due to the advantages including immunity to Faraday rotation, mitigation of multipath propagation effects, and reduced antenna orientation constraints. A number of CP antennas have been designed and published [1][2][3][4][5]. For more demanding applications, such as surveying systems employing differential GPS, an antenna covering both L 1 and L 2 bands is useful. In China, compass navigation satellite system (CNSS), or named "BeiDou," has provided navigation and positioning services compatible with GPS. Thus, a multi-band CP antenna which can operate both at GPS and CNSS frequency bands is required. With the rapid development of wireless communication systems, multiple frequency bands antennas [6-10] have been developed to meet increasing demand for a modern portable wireless communication standard in a single system. In particular, various types of designs related to multi-band CP antennas have been reported [11][12][13][14][15][16][17][18][19][20][21][22]. Singlelayer designs using square and circular patches with several slits have been demonstrated in Li et al. [11]. Stacked-patch multi-band CP antennas have also been introduced [12-17]. A dual-band proximity-fed stacked patch antenna presented in [15] could cover L 1 =L 2 =L 5 GPS band, but two L-shaped probes and a 0°-90°hybrid were employed to ensure RHCP

“…But their structures are complex for practical applications. A compact octagonal monopole antenna employing T-shaped quasi-self-complementary resonators for tri-band operation is presented in [18]; the T-shaped resonators can produce a new resonance obtaining multiband characteristic, but the operation band range is limited to around 5.8 GHz, while the antennas for UWB systems are in growing demand [19][20][21][22][23][24][25][26][27].…”

A novel multi-band monopole antenna using a pair of symmetrical mushroom-shaped self-complementary resonators (SCRs) is presented. The original antenna is composed of a monopole with arc-shaped edge and a beveled ground producing wide bandwidth with S 11 lower than −10 dB from lower frequency limit 2.5 GHz up to 15 GHz. Then a pair of mushroom-shaped SCRs, which produce a new resonance at 2.44 GHz, covering 2.05-2.60 GHz for 2.4 GHz WLAN band with S 11 lower than −10 dB, are embedded into the monopole. The antenna is simulated and measured; the results show that the proposed antenna can be used for 2.4/5.2/5.8 GHz WLAN, 3.5 GHz WiMAX, 3.7-6.425 GHz C band satellite communications and UWB systems.
