Single-Layer Dual-Band Satellite-IoT Terminal Antennas with Increased Beamwidth
Author: Ismael Vico Triviño, Miroslav Veljovic, Anja K. Skrivervik 

Abstract: In this Vision, we present an idea for a low-profile cost-effective, dual-band antenna with a small frequency ratio and enhanced beamwidth, suitable for dual-band bidirectional IoT satellite networks. A broader antenna beamwidth increases the number of Low-Earth-Orbit satellite contacts and decreases the IoT system latency. The proposed patch antenna uses a slot to enable the dual band operation and a set of parasitic elements to modify the radiation pattern in both frequency bands. We present an example operating in L band to illustrate the potential of this idea. The enhanced HPBW is on average 140º over the two frequency bands and all angular planes, which is an improvement of 41º in comparison to the same antenna without parasitic elements.
