Abstract
This letter presents a null-filled high-gain airborne antenna with metasurface for emergency communication. The proposed antenna consists of a monopole with two metal feeding loops, a metal cylindrical cavity and metasurface radome (MSR). By cutting the corners of the monopole and adding two loops, the aim is to direct vertical radiation electromagnetic waves. The cavity and MSR are used to achieve vertical null-filled radiation performance with high gain. Simulated and measured results exhibit that the antenna has a −10 dB bandwidth of 0.8–1.0 GHz, covering the emergency communication band, with a high gain (5.0–6.7 dBi). Furthermore, the null-filled level of the vertical radiation E-plane of the antenna is higher than −4.6 dB, and the H-plane maintains horizontal omnidirectional 360°radiation. The proposed airborne antenna is a good contender for emergency communication and also provides ideas for the antenna to meet both vertical null-filled and horizontal-omnidirectional radiation.
期刊介绍:
AEÜ is an international scientific journal which publishes both original works and invited tutorials. The journal''s scope covers all aspects of theory and design of circuits, systems and devices for electronics, signal processing, and communication, including:
signal and system theory, digital signal processing
network theory and circuit design
information theory, communication theory and techniques, modulation, source and channel coding
switching theory and techniques, communication protocols
optical communications
microwave theory and techniques, radar, sonar
antennas, wave propagation
AEÜ publishes full papers and letters with very short turn around time but a high standard review process. Review cycles are typically finished within twelve weeks by application of modern electronic communication facilities.
