Lower Ultra-High Frequency Non-Deployable Omnidirectional Antenna for Nanosatellite Communication System

Abstract

The concept of the nanosatellite comes into play in launching miniaturized versions of satellites or regarding payloads with minimizing cost and building time. The economic affordability of nanosatellites has been promoted with a view to launching various nanosatellite missions. The communication system is one of the most important aspects of a satellite. The antenna is a key element for establishing a communication link between the earth and the nanosatellite. The antenna and solar panel of the nanosatellite are two of the most vital components that profoundly impact antenna type and design. This paper proposes a non-deployable lower ultra-high frequency (UHF) antenna, strategically mounted on the satellite body, to address the constraints of deployment complexity and solar panel integration. The antenna was fabricated and performances measured with a 1U nanosatellite structure, which achieved resonance frequency at 401 MHz frequency bands with 0.672 dBi realized gain. The overall antenna size is 0.13λ × 0.13λ × 0.006λ. The major challenges addressed by the proposed antenna are to design a nanosatellite-compatible lower UHF antenna and to ensure solar irradiance into the solar panel to minimize input power scarcity.

A Novel Design of Complementary Split Ring Resonator Metamaterial-Based Low-Profile MIMO Antenna with Defected Ground Structure for S/C/X/Ka Band Applications

“…The ability to send data rapidly gives it a lot of leeway when it comes to using the spectrum, which might be helpful for mobile computing devices in the future. The broad bandwidth and rapid data transfer speeds are ideal for various applications such as short-range radars, surveillance devices, and medical imaging [ 2 , 3 , 4 ]. Wideband technology, which attempts to give high data rates and acceptable prices, is possible.…”

“…Therefore, variation in the area is represented by ∆L. The change is calculated using the following Equation (3).…”
