With the continuing development of mobile communications, the communication standards, which include operating frequencies and protocols, are also evolving. In order to accommodate these and future changes, antennas with characteristics of wideband and multiband are becoming a necessity. Hence, wireless communications industries are now demanding broadband antennas that are low-profile and low-volume structures.Conventional planar microstrip antennas are the most common form of printed antennas that have been used for many years. This is because these antennas offer advantages of low cost, conformability, and ease of manufacturing; however, the bandwidth of these types of antennas is highly restricted. Among different types of planar antennas, the slotted structure that offers the simplest structure is compact and radiates omnidirectionally; these features make it an excellent candidate for broadband applications.

A quad‐band dual‐polarized monopole with asymmetrical microstrip feed line is proposed in this article. The proposed antenna exhibits a linearly polarized behavior in three operating bands for UMTS, WLAN 2.4 GHz, and WiMAX 3.5 GHz applications while a circularly polarized nature in the lowermost band for the GPS/GLONASS. The multiband operation is achieved because of λ/4 mode of resonances of three different monopole lengths and 3λ/4 mode of longer monopole. The 3λ/4 mode of larger monopole is controlled by using an L‐Shaped stub to make it useful for WiMAX application (3.5 GHz). The circular polarization for GPS (band‐L1, 1575 MHz) is achieved by using an L‐shaped slit with the ground plane which leads to generation of magnetic current orthogonal to the longest monopole current corresponding to the lowermost resonance frequency. The proposed antenna exhibits impedance bandwidths of 11.22%, 7.9%, 6.84%, and 4.26% at the resonant frequencies of 1.5, 2.02, 2.46, and 3.51 GHz, respectively. The axial ratio bandwidth corresponding to the GPS band is 2.5%. The proposed antenna has dual sense circular polarization (LHCP in θ = 0° and RHCP in θ = 180°) and bi‐directional radiation patterns at GPS/GLONASS band along with stable gain and good efficiency in all the operating bands.

“…The frequency ratio of this antenna is adjusted by inserting four shorting posts into the patch and polarization switching among horizontal, vertical, and 45 • LP is realized by changing the states of the PIN diodes connected between the center of each edge of the patch and ground. Another dual-band dual-polarization capacitive-fed circular patch antenna operated at 1.575 and 2.4 GHz has been presented in [11], wherein a 90 • hybrid coupler chip is used to produce CP at 1.575 GHz and a pair of arc-shaped slots is embedded in the patch to radiate LP at 2.4 GHz. A dual-layer dual-band dual-LP reflectarray antenna using a cross dipole, modified phoenix loop, and square patch has been demonstrated in [12] for Ka-and W-band operation.…”

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.
