[Institution of Engineering and Technology 12th European Conference on Antennas and Propagation (EuCAP 2018) - London, UK (9-13 April 2018)] 12th European Conference on Antennas and Propagation (EuCAP 2018) - A Broadband Metamaterial Based Radar Absorber
摘要： In this article, a layer broadband metamaterial radar absorber is presented. Under normal incidence, it achieves at least 90% of absorption from 5.6 GHz to 9.1 GHz for both Transverse Electric (TE) and Transverse Magnetic (TM) polarizations. The structure is 12.7 times thinner than the wavelength at the center frequency. In order to understand the absorption mechanism, the three near unity absorption peaks at 8.87, 7.16 and 8.82 GHz have been used to study the electric and magnetic fields.

[Institution of Engineering and Technology 12th European Conference on Antennas and Propagation (EuCAP 2018) - London, UK (9-13 April 2018)] 12th European Conference on Antennas and Propagation (EuCAP 2018) - Textile-based UHF RFID patch antenna with H-slot
摘要： The paper presents an analysis and fabrication of two wearable textile-based UHF patch antennas with H-shaped slot for RFID applications. Both prototypes are fabricated by embroidering conductive yarn into denim textile. The two antennas differ in embroidered grid density. Performance of the designed and fabricated textile antennas have been evaluated in terms of the antenna gain, input impedance and radiation patterns. The RFID chip was integrated with the antennas and read-range was tested.

摘要： In this paper we present an overview of different antenna technologies for space-based instruments. We show that some of the designs that work well at gigahertz frequencies are difficult to implement at terahertz frequencies due to tight tolerance and rms surface finish requirements. We also show that antenna designs are dictated not only by the frequency of operations but also by the space platform of choice. In this paper, we also present ideas for low-profile terahertz antennas for implementation on SmallSat and CubeSat platforms.
