Cylindrical dielectric resonator antenna-based sensors for liquid chemical detection
(MDPI AG., 2019)
A compact, cylindrical dielectric resonator antenna (CDRA), using radio frequency signals to identify different liquids is proposed in this paper. The proposed CDRA sensor is excited by a rectangular slot through a 3-mm-wide ...
Low-profile frequency reconfigurable antenna for heterogeneous wireless systems
(MDPI AG., 2019)
A low-profile (0.21λg× 0.35λg× 0.02λg ) and a simply-structured frequency-switchable antenna with eight frequency choices is presented in this paper. The radiating structure (monopole) is printed on a 1.6-mm thicker, ...
