“…In [2], dual/tri-band operations are achieved by adopting the Manuscript fundamental and the spurious frequencies of the radiation element. In [3]- [5], multiband antennas with omnidirectional radiation are obtained by loading slots or parasitic stubs on the radiator. For the unidirectional antenna, multiple bands could also be achieved by stacking multiple patches with different sizes, however which leads to high thickness and complexity [6].…”

Abstract-A novel multiband patch antenna with unidirectional radiation is proposed by integrating resonators in the design. The multiple frequency bands are achieved based on a coupled resonators network. The topology and design methodology are detailed. The patch not only works as the lastorder resonator of the network but also the radiating element. Using this approach, multiple bands can be achieved without changing the shape of the radiation element. In addition, the operation bands can be adjusted by adjusting the coupling between the resonators. In this work, the four bands are designed at 4.6, 5.05, 5.8 and 6.3 GHz as a proof-of-concept. The prototype is fabricated and tested and measured results agree very well with the simulations, showing an excellent performance in terms of impedance matching, radiation patterns, gains and cross polarization discrimination (XPD).Index Terms-Multiband, patch antenna, resonator-based, unidirectional.

“…The bandwidth increment would be achieved at some cost, but it can benefit the users by providing a higher data rate with shorter download time. The various feed structures that can be used for bandwidth enhancement, resonance-mode realization, and size reduction of a monopole antenna include the probe [11][12][13][14], the microstrip [15][16][17], and the coplanar waveguide (CPW) [18][19][20].…”

This paper presents a unique and miniaturized dual-band coplanar waveguide (CPW-fed) antenna for modern wireless communication. A new technique of using a modified ground structure (MGS) and frequency shifting strips (FSS) has been employed in the design to achieve dual-frequency operation. The proposed antenna generates two separate impedance bandwidths and covers the minimum required frequency bands of GSM 1800, GSM 1900, and WiFi/WLAN 5 GHz. The proposed antenna is relatively small (17 × 20 mm 2 ) and operates over frequency ranges 1.51~2.06 and 4.43~6.70 GHz. The designed antenna was simulated using Ansoft HFSS, a FEM based simulator, and antenna characteristics, such as reflection coefficient, gain, radiation efficiency, radiation pattern, impedance bandwidth, VSWR, surface current, and electric field distributions, are reported in this paper. The effect of the antenna's key structural parameters on its performance is also analyzed.

“…Among the various types of antennas, circularly polarized antennas owing to their reducing polarization mismatch and multipath fading win a wide range of applications in the communication systems. As a good candidate, planar printed antennas [1][2][3][4][5][6][7][8][9][10][11] have the attractive features of small size, light weight, low profile and ease of fabrication. Some printed monopole antennas with multiple branches, such as F-shaped [1], G-shaped [2], double Tshaped [3], and C-shaped [4] ones, provide dual or triple current paths and resonate at different frequency points.…”

“…The band-notched UWB printed antennas reported in [5], by appropriately inserting bandpass filter structure, suppressed the dispensable bands and separated multiple narrow frequency bands from broadband. Other hybrid antennas composed of a single monopole and parasitic elements are proposed in [6][7][8]. The parasitic elements introduce another resonant mode, and tri-band performance is realized.…”

Abstract-A tri-band slotted F-shaped antenna with dualpolarization characteristics for wireless applications is presented. The crooked gap and F-shaped monopole are optimized to achieve triband operation of 2.4, 3.5 and 5.8 GHz with −10 dB impedance bandwidths of 20%, 14.1%, and 13.6%, respectively. Furthermore, by properly inserting an F-shaped strip on the wide-slot ground, the circular polarization (CP) with a 19% (3.3-4 GHz) 3 dB axial ratio bandwidth is obtained. The proposed antenna has a compact dimension of 42×40×1.6 mm 3 . A prototype of the antenna is fabricated and tested, and an agreement with simulated results is obtained.
