Abstract: A 3-D wideband high-gain circularly polarized array antenna with low radar cross section (RCS) is presented in this letter. Its element contains four 3-D radiation structures fed by a ...
Abstract: We propose a two-dimensional (2D) resonant-tunneling-diode (RTD) oscillator array to generate quasi-plane terahertz (THz) waves. Dual-RTD slot antennas are employed to form the 2D array ...
