polarized cavity-backed slot antenna the open literature. In this paper, a monofilar spiral slot antenna is proposed, which has a cavity-backed reflector to suppress the rearward radiation, providing wide 3dB axial ratio beamwidths in both principle planes. A planar cavity backed slot antenna array for 1.4 The Proposed Cavity Backed Slot Antenna In this report we describe a novel slot antenna designed for wideband car-. borne monopulse radars. A microstrip-fed cavity-backed slot (CBS) antenna is a slot radiator backed by a rectangular cavity and excited by a microstrip feed line. Design of Cavity Backed Slot Antennas Using FDTD (Omiya… Abstract— A cavity-backed slot antenna is thought to be one deal with the cavity-backed slotThe paper proposes a new prediction method antennas, we should use the geometrical theory of diffraction for frequency characteristics of the cavity-backed slot antenna, (GTD) [5] incorporated into the MoM.

connected to one side of the slot, and the outside conductor of the cable - to the other side of the slot. – The slot length is some (λ/2) for the slot antenna and (λ/4) long for the INF antenna. • The INF and the slot antennas behave similarly. • The slot antenna can be considered as a loaded version of the INF antenna. Cavity Backed Spiral AntennaSpiral Antenna Our LX series cavity backed spirals are broadband antennas designed for EMC, surveillance, direction finding, telemetry, and flush mounted airborne applications. These spirals can be used as a separate component antenna or as broadband feeds for reflector type dish antennas. Ultra-wideband Cork Substrate-Integrated-Waveguide Cavity ... The wideband SIW cavity-backed slot antenna topology depicted in Fig. 2 is adopted, making use of the bandwidth enhancement method [9].

A Cavity-Backed Broadband Circularly Polarized Slot/Strip ... It is demonstrated that the cavity-backed slot/strip loop antenna can achieve an axial ratio (d3 dB) bandwidth of 20% with good impedance matching. I. INTRODUCTION Cavity-backed slot antennas have two major advantages over cavity-backed wire antennas, such as dipole, helix, and spiral [1]. First, a slot antenna can be flush mounted
