A simple design of planar microstrip antenna on composite material substrate for Ku/K band satellite applications

Abstract

A straight forward design of rectangular slotted microstrip planar antenna fed by 50 ohm microstrip line is proposed for Ku/K band satellite applications. The radiating patch of the antenna occupies an area of 17 × 17 mm 2 and fabricated on 1.0 mm-thick ceramic filled bioplastic composite material substrate whose dielectric constant (ε r ) is 10.0. The dual resonant square-shaped antenna has been formed by inserting four arc shape slots at the corners with the combination of circle and square and wide square shape slot at the center. The results from the measured data show that the antenna has a lower resonant mode impedance bandwidth for S11 < À10 dB is of 18.4% (11.67-14.05 GHz) and upper resonant mode bandwidth is of 8. 2% (18.19-19.75 GHz) centered at 12.94 GHz and 19.04 GHz, respectively. The antenna prototype has achieved maximum gains of 3.1 dBi and 4.13 dBi with average radiation efficiencies of 75.3% and 86.4% for the lower band and the upper band, respectively. The numerical data analyses of both the measured and simulated results show relatively good agreement. Moreover, the consistent and symmetrical radiation patters of the proposed antenna make it suitable candidate for the Ku/K band satellite applications.

Dual‐wideband semi‐circular patch antenna for Ku/K band applications

“…From the perusal of Table , it is clear that the total volume of the proposed antenna is greater as compared to the antennas reported in Refs. by a factor of 4.38, 1.17, and 1.95, respectively, whereas it occupies lesser volume than antennas reported in Refs. by a factor of 4.7 and 1.11, respectively.…”

“…Since last few years, researchers have been investigating the implementation of the patch antennas in Ku/K band for satellite and radar applications but are still struggling to obtain the optimum structure with high gain and sufficient bandwidth. In order to obtain the compact structure with improved gain and radiation characteristics in the Ku/K band applications, different configurations of patch antenna structures have been reported by researchers . In this work, a compact dual‐wideband semi‐circular (substrate and patch both) shape micro‐strip patch antenna is presented for Ku/K band applications.…”

Design of Nature Inspired Broadband Microstrip Patch Antenna for Satellite Communication

“…It may be observed that the radiation patterns at all these frequencies are stable and maximum radiations are directed normal to the patch geometry. The antenna could serve as a potential candidate for Ku band of satellite communication and other suitable applications having better radiation performance as compared to the recently reported works [14][15][16]. …”
