“…This is especially true for the circularly polarized (CP) microstrip antenna which owns additional advantages of imposing less strict restrictions on orientation of the transmitter and receiver and mitigative multi path effects. A survey of recent literature indicates that a considerable amount of efforts have been devoted to the antennas with CP, for instance, CP antennas for bandwidth enhancement by using left handed (LH) metamaterial transmission line (TL) [8] and reactive impedance substrates [9], respectively, CP antennas with gain and directivity enhancement [10][11][12][13], omnidirectional radiations [14][15][16] and even dual-band or multifrequency operation with radiation pattern selectivity and polarization diversity [16][17][18][19][20][21][22][23][24][25].…”

“…Among them, the multiband antennas [16][17][18][19][20][21][22][23][24][25] with one or more CP bands have generated much attention because the multifunctional systems exhibit the benefits of high stability, reliability and integrity. Although these antennas present a miniaturized layout at the lowest resonant mode and decent CP radiation performances with good axial ratios (ARs), some of them are confined to mushroom structure which provides the shorted LH stub inductor through drilling via holes [16][17][18][19].…”

Abstract-A novel triple-band single-fed compact microstrip antenna with varied polarization states and radiation patterns is proposed based on two-dimensional artificial metamaterial transmission line (TL). The TL element is composed of complementary split ring resonators (CSRRs) etched in the ground plane and a capacitive gap embedded in the stepped-impedance conductor line. By inserting a 2 × 2 array of the original element in conventional patch and feeding the resultant structure with an annular-ring slot along the diagonal, an antenna working in three resonant modes (n = −1, n = 0, and n = +2) is engineered at three specific well-separated frequencies f −1 = 1.5, f 0 = 2.4 and f +2 = 3.5 GHz, respectively. As a result, both the numerical and experimental results illustrate that the antenna exhibits a patch-like radiation with pure linear polarization in the n = −1 mode, a monopolar radiation with circular polarization in the n = 0 and also an asymmetric quasi monopolar radiation with a hybrid linear polarization in the n = +2 mode. The antenna features compact whose patch occupying only an area of 0.246λ 0 × 0.246λ 0 × 0.03λ 0 at f −1 and exhibits groups of advantages such as high radiation efficiency. Moreover, the proposed prescription, free of any metallic via, perturbation structure and complicated feeding network, is of practical value and opens an alternative avenue toward new types of antenna with agile polarization capability and versatile radiation patterns.

Abstract-The phase-shifting characteristic of a novel composite right/left handed transmission line (CRLH TL) for two frequency points is analyzed in this paper. Samples of (90 • , 0 • ) and (180 • , 0 • ) phase-shifting TLs for two frequency points (f 1 , f 2 ) are deigned and the total length of the CRLH TLs has decreased by more than 77% compared to the conventional microstrip lines. Then a four way power divider made by three Wilkinson power dividers and interconnected with the (90 • , 0 • ) and (180 • , 0 • ) phase-shifting TLs is designed to feed an antenna with two different operating modes at two different frequency bands. Four radiating patches arranging symmetrically in a loop are printed in an upper substrate and connected with the four outputs of the feed network by four copper pins. When the four rectangular patches are excited by four sources with equal amplitude and phase at f 1 , metamaterial antenna with conical beam and linear polarization (LP) is achieved; while four sources with equal amplitude but 90 • phase difference for each adjacent output at f 2 leads to wideband antenna with broadside beam and circular polarization (CP). One antenna prototype with dual-band dual-mode dual-polarization property is fabricated and good agreements between simulation and measurement results are obtained. This single-feed patch antenna is valuable in wireless communications for its radiation pattern selectivity and polarization diversity.

A compact, dual-band metasurface-based microstrip patch antenna with both linear and circular polarization (CP) for multiband communication is reported in this work. The ingredients in the antenna design consist of a combination of metasurface and metamaterial inspired structures that are demonstrated as an effective technique to correct the beam squint problem and reduce the cross-polarized radiation, usually experienced by thick substrate-based broadband CP antennas. A fractal boundary metasurface is introduced to achieve CP over a small frequency band. Eight Electric-LC resonators are symmetrically placed in the same plane of the radiating patch to widen the CP bandwidth, correct the beam squint, reduce the cross-polarized radiation, and realize a subwavelength resonance of λ 0 /5.15 order. The measured impedance bandwidths (jS 11 j < À10 dB) of the proposed antenna are 7.8% (3.7-4.0 GHz) and 27.58% (5.05-6.65 GHz) in the lower and upper-frequency band, respectively. The measured 3-dB axial ratio bandwidth (ARBW) is 24.8% (5070-6510 MHz) at 5.8 GHz. The fabricated prototype has an overall size of 55 Â 55 Â 4.08 mm (0.696λ 0 Â 0.696λ 0 Â 0.051λ 0 at 3.8 GHz or 1.063λ 0 Â 1.063λ 0 Â 0.078λ 0 at 5.8 GHz) with a realized peak gain of 4 dBi in the lower band and 7.1 dBic in the upper band. The measured results are consistent with the simulation results.
