“…Several researchers have proposed different kinds of printed monopole antennas [10][11][12] that had exhibited larger IB but with limited gain. Some of the techniques to improve the performance of the printed monopole antenna include modi ed ground plane, frequency selective surface (FSS), arti cial magnetic conductor (AMC) and so on [13][14][15]. Among them highly e cient and useful technique is the use of FSS radiator that attracts a large research attention.…”

In this manuscript, a novel high gain Microstrip Patch Antenna (MPA) is proposed using frequency selective surface (FSS) dedicated to operate at ultra-wideband (UWB) frequency domain between 3.1 to 10.6 GHz. The patch has been modified to a semi-circular shape and a partial ground technique is incorporated that also comprises a truncated semi-circular metallic plate to achieve desired high bandwidth. The FSS layer beneath the antenna has successfully augmented the gain of the antenna prototype by about 5–6 dBi. This FSS layer comprises of a 4×4 array of uniquely designed unit cells that satisfy the UWB specification and each cell size is 12×12 mm2. The integrated design provides an impedance bandwidth (IB) from 3.14 to 12.6 GHz. The proposed model finds application in the Worldwide Interoperability for Microwave Access (WiMAX) band, the C and X-band for satellite applications and in Wireless Local Area Network. The antenna is printed on a double-sided FR4 glass epoxy of 1.6mm thickness. A parametric investigation is conducted both for the FSS unit cell and the integrated design to optimize the antenna parameters to be suitable for the UWB frequency range. The optimized antenna size is 26×30 mm2 and the integrated antenna size is 51×51 mm2. The antenna prototype has provided well similarity between simulated and measured results.

“…Although the printed planar monopole antennas exhibit wider bandwidth than a conventional microstrip, they have limitation of gain. In literature, many studies have been conducted in order to improve printed monopole antenna performance, such as modify ground plane, artificial magnetic conductor (AMC), frequency selective surface (FSS) and so on 4–6 . However, among these methods FSS is a useful technique and still attractive to the researchers due to its stability and high efficiency.…”

In this paper, a wideband, high gain planar trapezoidal monopole antenna based on single‐layer frequency selective surface (FSS) is presented. The antenna adopts an unconventional, dual‐metallic on a single‐layer FSS structure as a reflector layer to improve its performance. To validate the structure, the prototypes are fabricated and measured. The experimental results exhibit that the operating band of the proposed antenna covers 3.52–5.92 GHz, which corresponding to the impedance bandwidth of 50% with respect to the 5 GHz is the center frequency. Moreover, the proposed antenna offers a high gain with the maximum gain of 11.8 dBi at 5.1 GHz, and the gain is sustained higher 10.5 dBi for the entire bandwidth. The proposed antenna structure is a potential candidate for wideband applications and wireless local area network applications.

This paper presents a development and study of the capacitive shunt type RF MEMS switch. MEMS is a combination of mechanical and electromagnetic properties at the micro-level unit. The switch which can be used for switching purpose at RF and microwave frequencies is called RF MEMS switch. MEMS switch has many excellent advantages with potential characteristics and higher performances at radiofrequency. In this proposed design, a new type of capacitive switch is designed and analysed for RF electromagnetic properties in HFSS software and electromechanical properties in COMSOL multiphysics. The designed switch mainly consists of a substrate, co-planar waveguide (CPW), dielectric material and a metallic bridge.
