One of the most challenging works on compact antenna design is to maintain flexibility orientation. This paper demonstrates a coplanar waveguide (CPW) fed monopole with rubber substrate at 2.45 GHz center frequency for ISM band application. The proposed attained realized gain 4.06 dB radiation efficiency around 90% peak value and bandwidth 541.5 MHz. was designed using CPW structure. CST microw...

Since the FCC has announced to allow the unlicensed use of the industrial, scientific, and medical (ISM) frequency band by any potential users, wireless communications community has provided enormous opportunities for driving many wireless systems that can be communicated over short distances. For example, some practical applications are operated at the internationally available unlicensed ISM ...

Abstract This paper presents wideband split-ring antenna arrays based on substrate integrated waveguide (SIW) for Ka-band (26.5–40 GHz) applications. The array is fed by a 2.92 mm coaxial connector (K-connector) and the power equally distributed to each resonator. designed coplanar (CPW), SIW, CPW-to-SIW transition, coaxial-to-CPW two-stage SIW divider are described in detail. By using thin Rog...

The fractal antennas that have the multiband operation due to the self-similar property in fractal geometry, which plays a key role to create a fractal circular monopole patch antenna. The other important property that is, Space-filling property which actually determines the reduction in the size of the antenna. This property adds more electrical length in less volume which reduces the size of ...

This study presents a triangle director dipole antenna with rectangular impedance balun (RIB). The proposed consists of triangular director, coplanar waveguide (CPW) to stripline (CPS) transition line, and the RIB. substitutes typical planar quasi-Yagi antenna. has modified generates circular polarization. Also, RIB match an between CPW-fed CPS line. It obtains ultra-wide frequency band 4020 MH...

Introduction: Millimetre-wave fibre wireless applications [1] could profit from a small antenna that can be fully integrated with the microwave and optical components of the system. This can lead to smaller and more cost-effective fibre-fed antenna units. Active integrated antennas [2] are another application that could benefit from a directly integrated antenna. Printed antennas are the obviou...
