The use of spin waves as a signal carrier requires developing the functional elements allowing for multiplexing and demultiplexing information coded at different wavelengths. For this purpose, we propose system thin ferromagnetic layers dynamically coupled by rectangular resonator. We show that single double, clockwise counterclockwise, circulating modes resonator offer wide possibility control...

The excitation of the higher-order mode, in rectangular dielectric resonator designed was explored to enhance the antenna gain and detailed elaboration is presented in this paper. The antenna was fed by a 50Ω microstrip line through an aperture cut in the ground plane. Besides avoiding spurious radiation, this feeding technique gives flexibility in controlling the amount of coupling in order to...

In this paper, a Rectangular Dielectric Resonator Antenna (RDRA) with a modified feeding line is designed and investigated at 28GHz. The modified feed line is designed to excite the DR with relative permittivity of 10 which contributes to a wide bandwidth operation. The proposed single RDRA has been fabricated and mounted on a RT/Duroid 5880 (εr = 2.2 and tanδ = 0.0009) substrate. The optimized...

In this paper effects of coaxial probe feeding position and its penetration inside the radiating structure of an antenna has been presented in detail. For this purpose, a Rectangular Dielectric Resonator Antenna (RDRA) has been synthesized and analyzed. There effects on the characteristic behavior of antenna have been obtained. Optimized condition is established and relation between probe dimen...
