An Antenna is a metallic structure that transmits and receives radio waves. Antennas come in all shapes sizes from tiny microstrip antenna for biomedical applications to very big parabolic reflector antennas satellite communications. A Super Wideband Square Monopole designed on Arlon AD260A FR4 Epoxy with CPW-feed structure. Notched bands are obtained by embedding inverted E-shaped stub, using ...

In this article, a simple and compact dual bandnotched (DBN) super wideband (SWB) printed monopole antenna (PMA) has been proposed. The proposed antenna composed of a circular PMA, which is connected through a 50-Ω triangular tapered microstrip fed line (TTMFL) and a round-cornered finite ground plane (RCFGP). It exhibits a very wide frequency band from 1.6–25 GHz (ratio bandwidth of 15.63:1) w...

A novel configuration of a printed monopole antenna with a very compact size for satisfying WLAN operations at the 5.2/5.8 GHz and also for X-band operations at the 10 GHz has been proposed. The antenna includes a simple square-shaped patch as the radiator, the rotated U-shaped conductor back plane element with embedded strip on it, and the partial rectangular ground surface. By using the rotat...

A novel TM21-mode circularly polarized (CP) annularring microstrip antenna (ARMSA) is presented. The annular ring is designed working at TM21 mode, and conical radiation pattern is obtained. At the inner of annular ring, a simple ring-shaped feeding line is arranged to implement impedance matching and CP operation. Therefore, the antenna has good impedance and CP performance, as well as a compa...

This paper proposes a new triple-band monopole antenna based on Complementary Split Ring Resonators (CSRR) perturbing the ground plane (GND). The consists of an inverted-L-shaped fed by modified microstrip line with two CSRRs cut out plane. operational bands are independently controlled CSRR unit cell parameters. In addition, presents dual-polarization performance (vertical polarization at 2.4 ...

This paper presents a novel circular fractal ring monopole antenna for ultra-wideband (UWB) hardware with dual band-notched properties. The proposed consists of four crescent-shaped nested rings, tapered feeding line at the front dielectric material, and semicircular ground plane on backside. In this design, rings are used both as radiation element band rejection element. has bandwidth 9.03 GHz...

In this paper, a fully transparent antenna comprising of an Artificial Magnetic Conductor (AMC) backed Co-planar Waveguide (CPW) fed dual-ring monopole is presented. The and AMC structure achieve transparency due to the use AgHT-8 conductive oxide Plexiglas substrate. Measured performance shows impedance bandwidth 5.3 – 6 GHz (12.4%) in U-NII-1 U-NII-4 frequency band with peak gain 5.7 dBi whic...

Abstract— In this paper, the trapezoidal ring antenna using the conductor-backed CPW is designed and fabricated. The antenna has a broadband characteristic by the coupling effects through inserted the H-shaped parasitic patch. The conductor-backed CPW shows more stable characteristics than the CPW structure when there is occurred the variation between the feed-line and the ground plane in the f...
