Frequency Agile Triple Band Microstrip Antenna for WLAN / WiMAX Application
A frequency agile triple band microstrip antenna using defected ground structure for WLAN/WiMAX application is presented, in which frequency agility is electronically achieved by changing the bias voltage of varactor diode. A defected ground structure rectangular patch with dual inverted L-shaped fed with a cross shaped strip line is used to achieve multiple bands. Simulated results are validat...
متن کاملWide-band Slot Antenna for WLAN Application
This paper presents coplanar waveguide (CPW) fed slot antenna. A rectangular slot antenna is excited by a 50 ohm CPW with L-shaped tuning stub. It can achieves wide band from 2.0 GHz to 6 GHz which is the frequency band covered the standard IEEE 802.11a/b/g for use in WLAN (Wireless Local Area Network) and covered the WiMAX (Worldwide Interoperability for Microwave Access, 2-6 GHz). The charact...
متن کاملOmni Antenna vs. Directional Antenna
An antenna gives the wireless system three fundamental properties: gain, direction and polarization. Gain is a measure of increase in power. Gain is the amount of increase in energy that an antenna adds to a radio frequency (RF) signal. Direction is the shape of the transmission pattern. As the gain of a directional antenna increases, the angle of radiation usually decreases. This provides a gr...
متن کاملCompact triple-band monopole antenna for WLAN/WiMAX applications
A planar triple-band monopole antenna with a U-shaped stripline and a L slot is presented. The antenna is very compact with a size of 20 × 30 × 1.5mm3 and fed by a 50 Ω microstrip line with a defected ground. The measured −10 dB impedance bandwidth of the proposed antenna covers 2.33 GHz–2.51GHz, 3.25 GHz–3.82 GHz, and 4.83 GHz–8.4GHz, respectively, which meets the specifications of WLAN 2.4/5....
متن کاملCompact Triple Band Rectangular Microstrip Antenna for Wlan/wimax Applications
A compact triple band rectangular microstrip antenna (RMSA) for WLAN / WiMAX applications is proposed. The antenna operates at three resonance frequencies 2.4/3.2/3.5GHz Covering the WLAN/ WiMAX operating bands, IEEE WLAN protocol 802.11 b/g employs 2.4 GHz and WiMAX 3.5 GHz. The antenna was studied by means of simulations as well as practical measurements. The Triple band characteristics of an...
