Abstract :
The characteristics of new high gain multiband rounded corners dashed rectangular spiral microstrip patch antenna has been analyzed using a full wave analysis simulator. The antenna performance is sensitive to the cutting angles, which have been used to control the antenna gains up to 32.8 dB in some cases and bandwidths up to 20.1% in others. The proposed antenna is constructed on FR-4 glass-epoxy substrate of thickness 1.6 mm and relative permittivity 4.6. The radiation characteristics for the designed antenna such as return loss, radiation pattern and gain with respect to changes on the cutting angle are obtained using numerical simulations.
