Abstract

Due to the rapid evolution in electronics and wireless communication, the demand for the portable electronic devices operating at different frequency bands for multiple applications has been increased. Frequency reconfigurable antennas play an important role in wireless communication. In our proposed method we designed a micros trip patch antenna using HFSS software in order to increase return losses. The substrate used in this proposed design is FR4 with dielectric constant 4.4 and thickness 1. 6mm. The measured tuning of the designed antenna ranges from 2.5 to 5 GHz. The value of VSWR is in the range of 1-2 in this range of frequency. The return losses obtained in our designed antenna is 23Db

Key words: wireless, portable, antenna
