AbstractOne of the self‐complementary antennas is axially symmetric and three‐dimensional. Since this antenna has an axially‐symmetrical antenna, made of a finite‐sized plate, it becomes a hard‐to‐control multibeam antenna. to obtain a single beam we remove one of the unipole arrays from a self‐complementary unipole‐slot array antenna made of two ...

"Infinite Bandwidth" long slot array antenna
IEEE Antennas and Wireless Propagation Letters, 2005This work deals with the properties of a long slot array fed by an array of periodically located feeds spaced at a Nyquist interval. The study begins with the rigorous Green's function (GF) of a single long slot which was extended to an infinite array structure. After this, the input impedance properties of the array when fed by an array of /spl delta/

Conformal slotted waveguide array antenna
2012 IEEE International Workshop on Antenna Technology (iWAT), 2012A new slotted rectangular waveguide array antenna is introduced, which is constructed on the conformal cylindrical surface. Unlike other slotted waveguide arrays, this array has a beam with a large tilt angle from the broadside of the linear array. The array consists of a waveguide with inclined slots cutting in the narrow wall and a matching load at ...

Spiral slotted waveguide antenna array
2013 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2013Slotted waveguide antenna stiffened structure (SWASS) integrates the slotted waveguide antennas (SWAs) into the carbon fiber reinforced polymer (CFRP) composites in airplane skins. SWASS utilizes conventional half-wavelength rectangular slots as elements of the SWA array.

Log-periodic slot antenna array
Microwave and Optical Technology Letters, 2000Wideband operation of a microstrip-fed slot antenna is achieved by arranging the slots in a log-periodic manner. A nine-element log-periodic microstrip slot antenna array operating in the X-band is designed using the finite-difference time-domain method (FDTD).

Annular slot monopulse antenna arrays
IEEE Transactions on Antennas and Propagation, 1964This paper describes the design and performance of annular slot planar arrays which generate pencil beams and monopulse tracking beams in both principal planes. These planar arrays consist of a transmission line in the form of a radial waveguide whose upper plate contains annular groups of linear slots.
