Design of dual-band and high gain waveguide slot antenna ... A new kind of dual-band and high gain waveguide slot antenna is designed in this paper. By combining a folded plate and a double-layer metal structure with four apertures on its top floor, the proposed antenna has a dual-band characteristic and its gain reaches up to 11.9 dB with only 35 degrees (HPBW) of E-plane at 12.7 GHz and 12.1 dB with 39 degrees at 15.0 GHz. below 6cm slot antenna 20 slots 14.7 dbi 125 euro ... - PE1RKI 10ghz slot antennas are 125 euro, i used to sell them for 150 euro but i noticed i had competition in this area so i lowered price. 10ghz and 24ghz can have waveguide or sma input.

Radar Basics - Slot Antennas | Slotted Waveguide … Slot radiators or slot antennas are antennas that are used in the frequency range from about 300 MHz to 25 GHz. They are often used in navigation radar usually as an array fed by a waveguide.A single narrow slot radiator can also work on frequencies ±5 … ±10% besides its resonance frequency.

Waveguide Slot Array Antenna Snares 120 GHz |… As lower-frequency bandwidths are consumed by communications and other applications, researchers attempt to find cost-effective methods to make use of millimeter- wave frequencies. Using the 60- and 120-GHz bands for short-range, high-data-rate communications is one such example.
However, the grating lobes still appear in the plane including z-axis and diagonal kk’-direction due to the triangular lattice arrangement since the slot spacing in kk’-direction becomes the maximum as is shown in Fig.

The waveguide slot antennas we will be discussing have longitudinal slots in the broad face of stan-dard rectangular waveguide, parallel to the length of the guide. Figure 7-1 is a photograph of a typical waveguide slot antenna, with a total of 12 slots, six on each side, in WR-90 X-band waveguide for 10 GHz operation. Non-Resonant Slotted Waveguide Antenna Design Method n this paper a non-resonant slotted waveguide antenna design method is present-ed. The internal and external mutual coupling between adjacent radiat-ing slots is considered in the described meth-od.
