چکیده
The paper presents a new practical design for 4 × 1 planar switched array of dielectric filled waveguide antennas loaded with bow-tie shaped slots operating at 26.5 to 29.5 GHz 5G millimetre-wave applications. is realized as three-layered architecture, the top layer behaving radiator, bottom feed network and control circuit; common ground plane in middle layer, offering small form factor. are used achieve suitable bandwidth stable gain ∼ 13 dBi. proposed (DFW) shown offer 5 deg/GHz freq.-controlled beam-sweep 70° fixed freq. beam-steer. With only three switching ICs, it offers low power consumption fast beam-steering. Further, combination beam-scanning fixed-freq. beam-steering allows wide coverage antenna.

LTCC Partially-Filled Post-Wall Rectangular-Waveguide Slot Array Antenna in the Millimeter-Wave Band
In the millimeter-wave band, the series-fed array antenna is facing a problem of large transmission loss and narrow bandwidth by using a high-permittivity and large-loss-tangent material. In this paper, an air region is inserted in the half of the height in the LTCC waveguide of εr =6.6 and tanδ =0.013 to reduce the transmission loss. The reduction of the equivalent dielectric constant by the a...
متن کاملAn Ultralow Cross-Polarization Slot Array Antenna in Narrow Wall of Angled Ridge Waveguide
A low cross-polarization slot array antenna in the narrow wall of ridge waveguide is presented. A non-angled slot which is created in the narrow wall of the ridge waveguide is considered to be used as radiating resonant slot. The normalized resistance and normalized reactance curves are presented for design purposes. A six element slot array waveguide antenna with ridges on its narrow wall is t...
متن کاملSingle-layer waveguide slot array antenna with diaphragms
A single-layer waveguide slot array antenna of low cost and high performance for a millimetre-wave wireless communication system at 38 GHz frequency band is presented. The waveguide slots and diaphragms are located together on the cover plate of the antenna, which makes the antenna cost effective and highly efficient. Measurements show a cross-polarisation level below 26 dB and an efficiency le...
متن کاملDevelopment of A Compact and Low Profile Cavity Backed Slot Antenna Using Microstrip Gap Waveguide Technology
Proof of concept of a cavity backed slot antenna based on inverted microstrip gap waveguide (IMGW) technology is presented. Since the antenna is operating based on the first resonating mode of the cavity, it is more compact compared to the ordinary cavity backed slot antennas in which the second cavity mode is used for radiation. Furthermore, the proposed antenna element introduces lower lo...
