Index Terms:- Compact size, CPW, Slot antenna, RFID applications. I. INTRODUCTION Radio frequency identification (RFID) systems Slotted Waveguide Antenna - Keysight The slotted waveguide has achieved most of its success when used in an omnidirectional role To make the unidirectional antenna radiate over the entire 360 degrees of azimuth, a second set of slots are cut in the back face of the waveguide. When looking straight at the face of the waveguide you will be able to see straight through both slots. Research Article Waveguide-Based Antenna Arrays for 5G Networks

The main feature of these gap waveguide antennas is the flexibility (Design of 8 8 Slot Array Antenna based on Inverted
show that- it is possible to have an array antenna with BW of 15 % or more based on ridge gap waveguide technology. Keywords- Slot array antenna, corporate-feed, T-junction I. INTRODUCTION Planer waveguide slot array antennas and microstrip patch array antennas have been an interesting research topic among the antenna professionals since 1970s.
PARAMETRIC STUDY OF WAVEGUIDE SLOTS AND ANALYSIS OF RADIATION ... PARAMETRIC STUDY OF WAVEGUIDE SLOTS AND ANALYSIS OF RADIATION PATTERN FOR THE DESIGN OF WAVEGUIDE ARRAY ANTENNA M. Mondal Kalpana Chwala Space Technology Cell Department of E & ECE, IIT KGP Kharagpur-2, India A. Chakrabarty DEAN (Continuing Education) Electronics Electrical Communication Engg. IIT Kharagpur, India Antennas: The Slotted Waveguide Antenna (Planar Array of Slots) The problem arises because the physical dimensions along the E-plane is much shorter than that along the H-plane (the slotted waveguide is long but thin). In general, a longer antenna (or longer array) produces a narrower beam. This problem can be circumvented by arranging slotted waveguides in parallel, as shown in Figure 1. Figure 1.
Dec 11, 2017 · Abstract: A wideband 8 × 8 element slot antenna array based on ridge gap waveguide feeding network has been proposed for mmWave applications. The antenna subarray consists of four radiating slots which are excited by a groove gap cavity layer. Compared with previously published works, the proposed planar antenna array has quite wide impedance bandwidth. Slot antenna in ridge gap waveguide technology
