Abstract
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.

Highlights
UWB antenna for X band applications have created much attention in recent years
Many ultra wide band antennas ranging from 3.1 GHz- 10.6 GHz have been developed for X band applications
The behaviour the return loss is nothing but signal should not return back to the originating place. in triple seven shaped patch antenna can have the return loss value as -29 dB when the antenna is resonated at 11.4 GHz
Summary
UWB antenna for X band applications have created much attention in recent years. Many ultra wide band antennas ranging from 3.1 GHz- 10.6 GHz have been developed for X band applications. Miniaturized Triple Seven Shaped Microstrip Patch Antenna for X Band Satellite Communications introduced to operated in multiband frequency by changing the bridge gap between the dual U slots.[6] To detect the breast cancer in early stage the author introduced an antenna to resonate at 2.45 GHz and the results are in good agreement with simulated and fabricated antenna.[7] This author had done the research to wear the antenna into clothing to monitor the human activities such as body temperature, pressure, heartbeat rate etc.[8] A compact wearable antenna with ultra wide band works well in textiles engineering when antenna embedded on clothes.[9] The body worn antenna has been introduced in this paper with fleece substrate and simulated results shown clearly in this paper.[10]. The length and width of the feed line is about 0.8 mm X 0.8 mm
