Triple-band frequency agile Monopole antenna using PIN diode for wireless communications

摘要

A triple band monopole coaxial feed antenna which incorporates a ring shaped elliptical radiator operating on multi-frequency bands of 6.2 GHz, 7.6 GHz and 9.1 GHz is presented. Parametric analysis is performed along with frequency reconfigurability using PIN diodes. PEC and lumped RLC techniques are shown for implementation of PIN diode. Substrate variation is also performed with RT Duroid, FR4 and Taconic RF-60. This antenna covers WLAN, Body Area Networks, C-band and X-band applications.
