Design of a hexagonal monopole antenna capable of operating at 1.5 GHz, 2.5 GHz and 3.5 GHz serving GPS, WLAN and WiMAX applications is reported in this paper. The antenna is comprised of two concentric hexagonal rings with a split along its side length. It is fed by a microstrip line and is printed on a 40×40×3.2 mm3 FR-4 substrate. The effect of the split position on the return loss characteristics...
An inset-microstrip line-fed circular microstrip antenna with a rectangular slot on the radiation element for the dual-frequency operation is proposed. The circular microstrip antenna resonates at 1.58 GHz and 2.43 GHz, which enables it's usage in the wireless communication domain such as in Wireless Local Area Network (WLAN). The two excited modes, which are responsible for the dual-band operation...
A printed monopole antenna with microstrip-fed Sierpinski fractal geometry for dual wideband application is presented. The operating bands are adjusted with the design of modified Sierpinski triangle (radiating patch), ground plane and scale factor used to create a fractal shape. The simulated 10 dB (VSWR 2:1) reflection bandwidth for first resonant frequency is 60% (1.47 GHz2.7 GHz). It covers GPS,...
A printed trident shaped triple-band monopole antenna for wireless application is proposed. The antenna has three different resonant paths (forming a trident shaped structure), supports three resonances at around 2.43 GHz, 3.43 GHz and 5.22 GHz, which are reserved for WLAN and other wireless applications. Effectively constant radiation pattern and large impedance bandwidth has been observed. Impedance...
In this paper, a small printed antenna for mobile handset and WLAN applications is presented and discussed. The proposed antenna is a printed crescent shape monopole which is mounted on top of a defected ground plane. A 50 ohms microstrip line is used for feeding purposes. The performance of the proposed antenna was analysed and optimised to cover a wide bandwidth from 1.7 to 3.1 GHz. For validation,...
