A Scalable Solar Antenna for Autonomous Integrated Wireless Sensor Nodes

A novel scalable low-profile omnidirectional antenna that can be integrated underneath a solar panel is presented. The topology alleviates the effect of solar panel to the antenna while achieving a monopole-like radiation performance above a ground plane. A 72 × 72 × 11.5 mm
