Bent Configurations of Waveguide Slot Arrays
2019 IEEE 90th Vehicular Technology Conference (VTC2019-Fall), 2019The slot array antenna is used for pattern- critical applications including satellite communications and radar. In most mobile communications antennas, the pattern detail at the mobile terminal is not critical because of the distributed target of a multipath propagation environment.

Parasitic Slot Elements for Bandwidth Enhancement of Slotted Waveguide Antennas
2019 IEEE 90th Vehicular Technology Conference (VTC2019-Fall), 2019The use of extra slots in a slotted waveguide array for improving the impedance bandwidth is investigated. This has not been widely studied previously, probably because the directive pattern is a primary parameter for the waveguide array and extra elements are prone to spoiling the control of the pattern.

A matching slot pair for a circularly-polarized slotted waveguide array
International Symposium on Antennas and Propagation Society, Merging Technologies for the 90's, 1990The analysis and the design of the matching slot pair for a circularly polarized slotted waveguide array are described. The position and the size of the slots are numerically optimized to suppress reflection and to realize a desired polarization in the tilted beam direction, which contributes to the improvement of the antenna efficiency.

Tolerance analysis of coupling slot of waveguide slot array
2009 3rd IEEE International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications, 2009The tolerance of coupling slots is a major factor to determine the performance of the waveguide slot array. Consequently, it is significant to discuss the effects of coupling slots tolerance on the slot array performance. In this paper, the effects of slot dimensions on the resonance frequency are analyzed at first.

A Cylindrical Slot Waveguide Antenna
AMPC Asia-Pacific Microwave Conference,, 2005I x A Cylindrical Slot Waveguide Antenna is studied aiialytically. Externally, it is a long and thick cylindrical aiitenna excited by several maglietic current rings. Internally, it is a coaxial waveguide and energy is radiated outward tlirougli tlie slots.

A WAVEGUIDE SLOT SWITCHING TECHNIQUE
1963Abstract : A series of experiments is described on a novel technique which permits a slot radiator in a waveguide to switch its radiation on and off by means of a compact circuit located at the plane of the slow and within the wall thickness of the waveguide feed line.
