Summary: Due to the low available ambient power level, it is desirable to have a high gain and wide beamwidth antenna. However, it is difficult to achieve both simultaneously. In this study, a multi-port antenna using a nonuniform metasurface is proposed to overcome this limitation. By exciting three modes with complementary radiation patterns, and connecting each feed to a rectifier, the antenna achieves a wide beam and high gain effectively. The proposed rectenna has a beamwidth of 114 degrees with a gain ranging from 8 to 9.8 dBi, and an RF-to-DC conversion efficiency of 3%-67% at 2.45 GHz.

Summary: This article presents a novel low-profile self-duplexing antenna with high isolation for out-band operation applications. The antenna features two patches, one rectangular and one triangular, both utilizing the quarter-mode substrate integrated waveguide (QMSIW) cavity for enhanced performance. Miniaturization is achieved through capacitive slots. The antenna operates at both 5.8 and 9.8 GHz frequencies, with impressive alignment between measured and simulated results. It has compact dimensions and 40 dB isolation between its ports, as well as consistent radiation patterns at both frequencies. The gains at 5.8 and 9.8 GHz are 4.1 and 4.6 dBi, respectively. The antenna's frequency bands can be independently tuned by adjusting the size of the capacitive slots. The article also provides valuable insights into the antenna's functionality and versatility, making it a valuable asset for dual-band wireless communication applications.

Summary: A new self-oscillating mixer (SOM) has been proposed in this paper, which includes a dielectric resonator (DR) antenna fed by a half-mode substrate integrated waveguide (HMSIW) on an FR4 epoxy substrate using hybrid integrated circuit technique. The high quality factor of the HMSIW resonator and the higher order HEM13 delta mode excitation of the DR radiator contribute to the excellent phase noise performance of the oscillator and the high directivity of the antenna, respectively. The phase noise, estimated LO power, and conversion gain are -102.5 dBc/Hz at 1 MHz offset, 8.74 dBm at an oscillation frequency of 24.15 GHz, and 8.5 dB, respectively. The figure-of-merit for the oscillator is -172.8 dBc/Hz.
