“…In particular, antennas with unidirectional radiation patterns of various beam widths are of interest as they may be mounted on walls or vehicles without degrading their electrical characteristics and without affecting the aesthetics of the mounting bodies. Although PMA has a simple and compact antenna structure, it is a good competitive solution for such a system because of wide impedance bandwidth [1][2][3]. There are lots of techniques such as a bevelling, a shorting strip, a multiple feeding strip and loaded plate to increase the impedance bandwidth in the PMA [4][5][6].…”

Abstract-A wideband circular polarized planar monopole antenna array (PMAA) that employs dual band-notched characteristics is presented in this paper. The proposed antenna array is formed by four pinwheel-shaped folded planar monopole antennas (PMAs) in order to improve the performance of circular polarization and high directivity. Also, it achieves low-profile, small-sized structure. The attractive characteristics of the proposed PMAA are a wide impedance bandwidth of 87.3% (1 GHz to 2.55 GHz), the 3 dB axial-ratio (AR) bandwidth of 92.3% (1.05 GHz to 2.85 GHz) excluding dual notch bands, the total bandwidth of 35% (1.8 GHz to 2.55 GHz), and the maximum gain of 8.24 dBic within the total bandwidh. Moreover, in order to generate dual band-notched characteristics in a circular polarized antenna, a folded PMAA with multiple U radiators and inverted W slots is proposed.

“…In order to satisfy the IEEE 802.11 WLAN standards and the WiMAX standards simultaneously, multiband antennas with large impedance bandwidth and planar structure are required. For this, several types of antennas have been proposed for WLAN/WiMAX applications, such as planar inverted-F antennas (PIFAs) [1][2][3], monopole antennas [4][5][6][7], and slot antennas [8][9][10][11][12]. The PIFA antenna provides many desirable characteristics such as multiband operation and compact size while it has a complex structure and its 3D structure may be challenging in fabrication.…”

Abstract-A novel circular slot antenna with two pairs of T-shaped slots is proposed for satisfying WLAN and WiMAX applications simultaneously. The proposed antenna consists of a 50 Ω microstrip feed line with a tuning stub on the top and a circular slot ground plane with an embedded straight strip and two pairs of etched T-shaped slots on the bottom side. By carefully adjusting the length of the straight strip, the proposed antenna can operate in two separate bands. With the use of two pairs of T-shaped slots, a new resonant frequency has been excited, and the impedance bandwidth can be widened. The measured results show that the 10 dB return loss bandwidths of the proposed antenna are 760 MHz (3.18-3.94 GHz) and 1002 MHz (5.05-6.07 GHz), which can cover both 5.2/5.8 GHz WLAN bands and 3.5/5.5 GHz WiMAX bands. The design evolution and parametric study of the proposed antenna are presented to provide information for designing and optimizing such an antenna. Furthermore, good omnidirectional radiation patterns with appreciable antenna gain are obtained over the operating bands.

“…Along with the compact size, the antenna should be low cost, light weight, less fragile, low profile, and finally, the fabrication methodology should be simple. Many compact printed monopole antennas were fabricated for wireless applications and reported in the literature [1][2][3][4][5][6][7]. Most of these antennas are designed for applications either in WLAN [1][2][3][4][5] or worldwide interoperability for microwave access (WiMAX) [6,7].…”

Abstract-The design of a simple microstrip fed folded strip monopole antenna (FSMA) with a protruding stub in the ground plane for the application in WLAN and RFID is presented. The antenna has two resonant paths, one in the radiating element (folded strip) and the other in the protruding stub of the ground plane. It supports two resonances at 2.4 GHz and 5.81 GHz, which are the center frequencies of WLAN and RFID. Effectively consistent radiation pattern and large percentage bandwidth have been observed. The measured percentage fractional bandwidth at 2.4 GHz (2.05 GHz to 2.86 GHz) is 32.99, and the percentage fractional bandwidth at 5.81 GHz (5.55 GHz to 6.14 GHz) is 10.11. The proposed antenna is simple and compact in size, providing broadband impedance matching, consistent radiation pattern and appropriate gain characteristics in the WLAN and RFID frequency regions.
