Abstract
A broadband coplanar waveguide (CPW)-fed monopole antenna based on conventional CPW-fed integration with an organic solar cell (OSC) of 100% insolation is suggested for Ku band satellite communication. The proposed configuration was designed to allow for 100% insolation of the OSC, thereby improving the performance of the antenna. The device structure was fabricated using a Leiterplatten-Kopierfrasen (LPKF) prototyping Printed circuit board (PCB) machine, while a vector network analyzer was utilized to measure the return loss. The simulated results demonstrated that the proposed antenna was able to cover an interesting operating frequency band from 11.7 to 12.22 GHz, which is in compliance with the International Telecommunication Union (ITU). Consequently, a 3 GHz broadband in the Ku band was achieved, along with an enhancement in the realized gain of about 6.30 dB. The simulation and experimental results showed good agreement, whereby the proposed structure could be specifically useful for fixed-satellite-services (FSS) operating over the frequency range from the 11.7 to 12.22 GHz (downlink) band.
Highlights
Wireless communications have been undergoing rapid development and are highly requested for communication services over long distances that use high data rates [1]
It is comprised of a rectangular patch with a dimension of 15.2 × 6.5 mm2 sandwiched between the organic solar cell (OSC) and substrate, where a gap of
Since the solar array backside is mounted onto the backside of the antenna, the antenna performance would not interfere with the solar cell
Summary
Wireless communications have been undergoing rapid development and are highly requested for communication services over long distances that use high data rates [1]. In remote areas where it is difficult to establish a grid electricity transmission, the operation of a stand-alone communication service for long-term use is becoming easy with the help of an independent and continuous supply of electricity. Such steady power supply can be realized by means of photovoltaic (PV) technology. PV devices can be successfully utilized to convert sunlight energy into electricity via solar cells comprised of various architectural designs and active materials [2,3,4]. The integration of solar cells with antennas can overcome the problem of autonomous communication systems and helps in reducing design costs
