چکیده
A novel application of leaky-wave antennas (LWAs) as integrated and multiplexers/demultiplexers is proposed experimentally demonstrated in the millimeter-wave band at 60~GHz. The first demultiplexing an oblique-incident free-space wideband plane wave into $2N$ channels using $N$ LWAs with different beam-scanning laws. second $N$--channel multiplexing pairs identical each other's far-field, where LWA pair designed such that broadside frequency center its respective channel. Friis transmission equation used to analytically demonstrate two applications Gaussian radiation beams. are then implemented reflection-cancelling slot substrate waveguide (SIW) technology. Full-wave simulations by incident four LWAs. Finally, conducting horn-to-LWA LWA-to-LWA measurements successfully showing broadband discrimination. provide a simple, compact, high-efficiency, low-profile multiplexing/demultiplexing solution high-integration capability other circuitry. Compared conventional multiplexers, does not require matching networks can be directly scaled higher frequencies same architecture.

Leaky CPW-Based Slot Antenna Arrays for Millimeter-Wave Applications
A uniplanar leaky-wave antenna (LWA) suitable for operation at millimeter-wave frequencies is introduced. Both unidirectional and bidirectional versions of the antenna are presented. The proposed structure consists of a coplanar waveguide fed linear array of closely spaced capacitive transverse slots. This configuration results in a fast-wave structure in which the = 0 spatial harmonic radiates...

متن کاملAn Electronically Switchable Leaky Wave Antenna
We report an electronically switchable dielectric leaky wave antenna. The main beam angle can be electronically steered using p-i-n diodes. The diodes are used as switches to control the radiation from two sets of gratings with different periods, thereby switching the main beam angle. Beam steering is achieved at a single fixed frequency; no frequency sweeping is necessary. A microwave prototyp...
