Miniaturized Triple Seven Shaped Microstrip Patch Antenna for X Band Satellite Communications

Objective: In digital world, the X band or Super High Frequency is widely used by military forces in Satellite Communication for beyond line of sight communications. X band is most preferable band for military users as antenna able to operate at frequency bands which is suitable for military user’s needs. Methods/Statistical Analysis: A Compact triple seven shaped microstrip patch antenna is considered. By employing two rectangular slots that can change the conventional rectangular slot into seven shaped patch, the antenna able to operate in single band in the X band satellite communication. However, in order to meet military radio spectrum the frequency range is specified at 8 to 12 GHz and wavelength range is about 3.75 to 2.5 cm. Findings: The proposed antenna consists of Rogers RT/duriod 5880 substrate material with the dimension of 50mm X 50mm and triple seven shaped radiating patch with microstrip feed line having the length and width of 0.8mm X 5mm. The compact triple seven shaped microstrip patch antenna resonates at the frequency of 11.4 GHz with -29.03dB return loss. The proposed antenna gain is 2.24dBi. The simulated results show that the proposed antenna operates with stable gain, good return loss, VSWR and consistent radiation efficiency. The good agreement is achieved and it is more suitable for X band applications. Application/Improvements: The applications of the X band are Radar communication, satellite Communication, wireless computer networks and military forces.
