Proof of concept of a cavity backed slot antenna based on inverted microstrip gap ‎waveguide (IMGW) technology is presented. Since the antenna is operating based on the ‎first resonating mode of the cavity, it is more compact compared to the ordinary cavity ‎backed slot antennas in which the second cavity mode is used for radiation. Furthermore, ‎the proposed antenna element introduces lower lo...

Various broadband multi-resonator gap-coupled configurations of equilateral triangular microstrip antenna and its compact variation, half equilateral triangular microstrip antenna, are proposed. The broadband proximity fed equilateral triangular microstrip antenna yields bandwidth of more than 650 MHz (~44%), whereas equivalent proximity fed gap-coupled half equilateral triangular microstrip an...

The superinductor, the lumped-element LC resonator, and the microstrip feedline line were fabricated within the same vacuum cycle using multi-angle electron-beam deposition of Al films through a nanoscale lift-off mask. To minimize the spread of the junction parameters, we have used the so-called“Manhattan-pattern”bi-layer liftoff mask formed by a 400-nm-thick e-beam resist (the top layer) and ...

New emerging wireless systems that operate at millimeter wave frequencies, such as high data rate 60-GHz transceivers for wireless personal area networks (WPAN), use integrated antennas. The small wavelength at 60-GHz enables the antenna to be integrated either in the package or on the chip. However, on-chip integrated antennas for 60-GHz systems, built on a conductive substrate, such as comple...

Microstrip fed inset patch antennas embedded in planar and cylindrically curved surfaces are introduced to be used in Body Area Networks (BANs) presented. These antennas are designed as wearable antennas for industrial, scientific and medical (ISM) band wireless communication networking. The proposed antennas consist of 50 Ω microstrip line feeding inset patch printed on the front face of diele...

In this paper, a new de-embedding technique with Look-Up Table (LUT) is proposed for accurate and efficient characterization of interconnects, particularly printed circuit board (PCB) transmission lines including microstrip and stripline. LUT is pre-created to cover various fixture effects including the reference structures inside and/or outside test printed circuit boards (PCBs). The pre-estab...

This paper presents the bandwidth and gain enhancement of microstrip patch antenna using EBG for X band (10 Ghz) application. The surface waves must be suppressed to increase the bandwidth and gain by using EBG. By using EBG the stop band characteristics is created over certain frequency and that has been adapted to suppress the surface wave and to enhance the gain and bandwidth of the antenna ...
