“…And planar inverted-F antennas (PIFA) are also showing a good performance at the desired dual or triple bands with candidates of a PIFA consisting of three separate short-circuited patches with a triple feed integrated [8], a PIFA with two shorted branches [9], a meander patch PIFA structured by two shorting pins [10]. Furthermore, some hybrid antennas composed of a simple monopole and parasitic elements in [11,12], with the technology of defected ground plane in [13,14] or with band-rejected designs of the printed wideband antenna in [15] are reported. The aforementioned designs introduce additional resonance modes or suppress the dispensable bands for accurate expected narrow bands mitigating the interference.…”

A novel compact monopole antenna with triple-band operation is proposed in this paper. The proposed antenna, fed by a 50-Ω microstrip line, consists of an inverted-L-shaped microstrip feed line loaded with a parasitic strip and a protrudent mirrored quasi-F-shaped strip on the ground plane, with a compact overall size of 20 × 25 mm 2. The protrudent mirrored quasi-F-shaped strip is aimed to excite a resonant mode at 2.4 GHz. Meanwhile, with the introduction of the parasitic strip to the inverted-L shaped strip, two adjacent resonant frequencies at 5.2/5.8 GHz are obtained. The numerical and experimental results exhibit the designed antenna operates over triple frequency ranges, satisfying the standards of wireless local area networks (WLAN) both in IEEE 802.11 b/a/g at 2.4-GHz, 5.2-GHz, and 5.8-GHz. Besides, the antenna is fabricated and measured, and the simulation and measurement results of the return loss, radiation patterns and peak antenna gains are studied showing that the presented antenna is in good performance.

Abstract-A wideband slotted multifunctional reconfigurable antenna is proposed for WLAN/WiMAX/UWB/PCS-DCS/UMTS applications. The proposed antenna consists of monopole and spiral sections and microstrip feeding. A microstrip patch on FR4 substrate provides wideband return loss for each application. Total area of the antenna is 34×45 mm 2 that satisfies all the requirements for different applications in a low profile structure. Reconfigurable design is used in this antenna using RF MEMS switches. The proposed antenna has a nearly omnidirectional radiation patterns (doughnut shape) in different frequency bands. The notch is embedded in the ground plane to improve the impedance matching, and the dimensions of this notch are optimized. Moreover, the variation of group delay is about ±2 ns in UWB application. Also a prototype of the proposed antenna is fabricated, and the results are compared with those obtained from simulations. Measured return losses are in good agreement with simulated ones. The proposed antenna has the advantages of multifunctional operation, low profile, low cost and omnidirectional pattern.

“…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.…”

“…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.…”

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.
