Multiband, frequency reconfigurable, and metamaterial antennas design techniques: Present and future research directions

Abstract

In recent years, the demand for multifunctional components has increased tremendously. Advancement in integrated technology has provided researchers with ample capability to fit diversified applications operating at different frequencies in one wireless device. Integration of multiband antennas in conjunction with frequency reconfigurability offers an optimal antenna design. In addition, the incorporation of metamaterials yields controllable and promising radiation properties. This paper contributes uniquely to the field of antenna design in two ways. First, it provides the domain and technical aspects associated with multiband, frequency reconfigurable, and metamaterial antennas. Second, it provides a critical review of literature. The paper additionally highlights the deficiencies in the design techniques reported in the literature.

A compact multiband band slot antenna for wireless applications

“…The most imperative topic for researchers nowadays is multiband microstrip patch antennas. Down the progress of navigation, positioning and WLAN applications on cell phones, antennas on such devices are expected to support multiple bands functioning . Low profile frameworks have drawn the enthusiasm of the researchers towards the microstrip patch antennas (MPAs).…”

“…A test in planning such wireless systems is to configure smaller, ease, multiband and broadband antennas. For this, numerous promising double or multiband antennas outlines, such as, the microstrip‐line‐sustained antennas, Slots, fractals, metamaterials, , DGS etc.…”

Rectangular Zigzag Microstrip Patch Antenna with Swastik Shape DGS for WLAN, C and Ku-Band Applications

“…Different configurations for defected ground structures have been used to implement microstrip patch antennas showing variable performance characteristics [9][10][11][12]. Researchers have also put their efforts in exploring multiband, frequency reconfigurable, and metamaterial antennas design techniques and miniaturized circularly polarized coaxial fed superstrate slot antenna for L-band application [13,14]. In this letter, a triple-band microstrip-fed patch antenna has been designed for WLAN, C-band and Ku-band applications.…”

A compact decagonal‐shaped UWB monopole planar antenna with truncated ground plane

“…Given these aforementioned abilities, a computationally efficient UWB antenna must possess effective integration capability and compact size. Nevertheless, designing compact antennas is a challenging issue since; reducing the dimensions of the ground plane shortens the current length path thereby resulting in poor antenna matching at lower frequencies …”
