Single slot cavity antennas assembly

By Author

Fig. 3 Three monopole on-chip antennas, one transmit and two receive antennas on a single silicon chip. Fig. 4 Three wide slots backed by a cavity for each monopole antenna. The depth of the cavity is 0.5 mm. The combination of the slot with the monopole improves the overall efficiency of the antenna.

Munson, Single Slot Cavity Antennas Assembly, U.S. Patent No. Dual-slot feeding technique for broadband Fabry- Perot cavity antennas

A compact design for dual- and wide-band cavity-backed slot antenna is presented in this letter. The slot antenna is fed by two microstrip lines on the top of the substrate for 900- and 1800-MHz ...

Single-Layer Cavity-Backed Slot Array Fed by Groove Gap ... A $4 \times 4$ slot array has been designed using this concept. The goal of this letter is to demonstrate the viability of groove gap waveguides and coaxial cavities for the design and fabrication of high-frequency single-layer slot-array antennas. Simulation results as well as measurements are shown. IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, VOL. 54, NO. 5 ...

In one embodiment, the present invention provides an antenna array for transmitting one or more beams in a communication system. The antenna includes a cavity slot antenna array that is adapted to be operatively connected to a beam forming module (e.g., via a plurality of signal feed lines that are connected to radiating signal probes).

Cavity-Backed Slot Array | Antenna Magus Cavity-backed slots allow for very efficient low-loss structures at high frequencies, but often require complex feed structures. By using a single cavity backing for a number of slots and leveraging the modal distribution in the cavity to realize the excitation distribution of the slot array the complexities...
