“…Moreover, a pair of step-slots [4] or a pair of properly-bent narrow slots [5] embedded near the non-radiating edges of a rectangular microstrip patch have also been reported. Another dual-band antenna applying two arc-shaped slots integrated close to the edge of the circular microstrip patch has been studied in [6]. These antennas exhibit linear polarization (LP) at both bands.…”

“…These antennas exhibit linear polarization (LP) at both bands. In [7,8], dual-band circular polarization (CP) antennas have been demonstrated. A slot-loaded square patch with two feeding points has been used in [7], wherein four equal shaped slots are loaded close to the edges of the patch.…”

“…A slot-loaded square patch with two feeding points has been used in [7], wherein four equal shaped slots are loaded close to the edges of the patch. A small circular patch surrounded by two concentric annular-rings that are loaded by an unequal lateral cross-slot ground plane has been presented for dual-band CP operation [8]. A CP antenna using metamaterial for WiMAX applications has been presented in [9], wherein two split ring resonators (SRR) are implemented to realize CP.…”

“…Therefore, this structure works in a single band with CP radiation. However, the slot-loaded antennas mentioned in [1][2][3][4][5][6][7][8] act as dual-band antennas because the loaded pair of slots introduces another higher order resonant frequency and modifies the current distribution on the band to obtain a radiation pattern similar to the lower resonant frequency [1]. In [10], an aperture coupled square microstrip patch with a dual-band polarization reconfigurable capability has been described for wireless local area network (WLAN) systems.…”

Abstract-In this study, a new slot embedded microstrip antenna for dual-band dual-polarization operation is proposed. The antenna comprises a single layer structure with a square radiating patch where the feed port is located along a diagonal line of the patch. Two narrow slots parallel and close to the radiating edges of the patch are loaded on the patch. Patch without slots is resonated for X-band and another resonant frequency at Ku-band is obtained by loading the slots. Moreover, the loading of slots helps to produce two orthogonal modes of equal amplitudes at X-band. Furthermore, the feed port along the diagonal line of the square patch makes it possible to radiate different polarization at the two bands. The antenna can radiate circular and linear polarization at X-and Ku-band, respectively. Current distributions of the antenna at both bands are observed to explain the behavior of the antenna and confirm the polarization characteristics at X-and Ku-band. A 3-dB axial ratio bandwidth of 1.35% is achieved. Measured gains of 6.60 dBic and 5.80 dBi with good radiation performances are achieved at X-and Ku-band, respectively. Moreover, good measured cross-polarization levels of 27.6 dB at Xband and 15.6 dB at Ku-band are obtained. The measured performances of the fabricated antenna are consistent with simulated results.

In this paper, a dual arm patch antenna for wideband applications has been presented using metamaterial. The proposed antenna has a percentage impedance bandwidth (S 11 \ -10 dB) of 65.1 % (at center frequency of 3.7 GHz). The proposed structure consists of two arms having rectangular patch etched with complimentary split ring resonator (CSRR) while ground plane is partial. The fabricated structure has substrate dimensions of 40 9 40 9 1.6 mm 3 and radiating element size of 2 9 (10 9 14 mm 2 ) showing compact size and meets various wireless standards such as WLAN, Wi-Fi and WiMAX. Wideband characteristic is obtained by combining two hybrid modes of patch and a resonant mode exhibited by CSRR which is etched on the rectangular patch. The metamaterial-inspired dual-arm patch antenna exhibits monopole-like radiation patterns in xz-plane and dipolar-type in xy-plane with an average gain of 2.31 dB and an average radiation efficiency of 94.8 % in the working band.
