A new multiple C-slotted microstrip patch antenna is proposed in the present study. A patch antenna is a wide-beam narrowband antenna. The microstrip patch antenna consists of a very thin metallic strip (patch) placed a small fraction of a wavelength above a ground plane. The patch can be designed in any possible shape and normally made of conducting materials such as copper or gold. This study...

Emerging digital radar concepts such as orthogonal frequency-division multiplexing (OFDM) allow flexible signal generation. This opens up new opportunities in waveform design a multiple-input multiple-output (MIMO) system introducing coding for multiplexing. In this article, coded MIMO OFDM waveforms are proposed and investigated that continuous simultaneous wideband transmission all transmitte...

In this paper, we adopt a three-stage based uplink channel estimation protocol with reduced pilot overhead for an reconfigurable intelligent surface (RIS)-aided multi-user (MU) millimeter wave (mmWave) communication system, in which both the base station (BS) and RIS are equipped uniform planar array (UPA). Specifically, Stage I, state information (CSI) of typical user is estimated. To address ...

Transport current capability of MgB $_{2}$ multifilamentary wires is intrinsically affected by the self and mutual magnetic inductance between superconducting filaments, which a problem that depends on geometrical distribution filaments...

The Caltech Submillimeter observatory (CSO) is one of the World’s premier submillimeter telescopes. It consists of a 10.4 meter diameter Leighton radio dish situated in a compact dome near the summit of Mauna Kea, Hawaii. The telescope has been operating under a contract from the National Science Foundation on a regular basis since 1988. For the first time heterodyne Superconducting-Insulating-...
