A small wideband microstrip patch antenna is introduced. The antenna is designed to function in the 5-6 GHz wireless LAN bands. It achieves multi-band functionality through the addition of a slot to a square patch (21 mm by 21 mm by 2.6 mm). The proposed antenna also generates circular polarization and has a 3 dB axial ratio bandwidth of 2.8%. The impedance bandwidth of the antenna is more than...

In this paper a novel approach for analyzing penetration of electromagnetic radiations in human tissue at different frequency is presented. Moreover, we concentrated our work on analyzing the other related factors describing system performance like return loss& Voltage Standing Wave Ratio (VSWR). consider We use different communication frequencies to simulate antenna for analyzing variation in ...

A simple electromagnetically coupled broadband printed microstrip antenna suitable for multifunctional wireless communication bands is presented. V-slots and corner notches are employed in a rectangular patch to achieve broadband operation. The proposed antenna has a 2 : 1 VSWR bandwidth of 51% from 3.75 GHz to 6.33GHz. The simulated and measured reflection characteristics of the antenna along ...
