Abstract:
A new design or compact co axial feed ‘o’ slotted corner truncated rectangular microstrip patch antenna is proposed. This proposed design enhanced bandwidth and reflection coefficient. Co axial feed ‘o’ slotted corner truncated rectangular microstrip patch antenna is designed by adopting a rectangular patch on FR4 substrate with 4.3 permittivity and 1.5 thickness. The circular ring on patch not only achieve a higher bands but it also used to for better tunning. This proposed antenna operated on 3.75 GHz. This antenna is used for S-Band Applications such as WiFi, GPRS etc. The Band Width is achieved approximate 15 % of operating frequency.
