A Parasitic Decoupling Structure for Dual-Polarized Patch Antenna Arrays
IEEE Antennas and Wireless Propagation Letters, 2023In this letter, a simple parasitic structure consisting of a microstrip L-section array and a microstrip U-section array is proposed for mutual coupling reduction of dual-polarization (DP) patch antenna array. The additional coupling paths are introduced

A Decoupling Structure for Mutual Coupling Suppression in Stacked Microstrip Patch Antenna Array
IEEE Antennas and Wireless Propagation Letters, 2022A simple decoupling structure for a stacked microstrip patch antenna array is proposed. By loading a shorting C-shaped structure and a square ring, the mutual coupling between stacked microstrip patch antenna elements can be adjusted at the low- and high-

Circular microstrip antenna array
Antennas and Propagation Society Symposium 1991 Digest, 2002The radiated fields due to a circular array of patch antennas are investigated. The aperture method is used to determine the fields of the patch; for this initial study, the effects of mutual coupling are not included. The dependence of the radiated fields on the array geometry is examined for a frequency of 10 GHz and a substrate dielectric constant ...

A Standing-Wave Microstrip Array Antenna
IEEE Transactions on Antennas and Propagation, 2010The design and analysis of a single-layer standing-wave microstrip array antenna are presented. No quarter-wave transformers or power dividers are present in the design. The main emphasis of this paper is on the multiple reflections in the feedline causing a standing-wave of a higher-order mode.

Compact circularly-polarized microstrip array antenna
2010 Loughborough Antennas & Propagation Conference, 2010AbstractThis article first presents a compact circularly polarized single patch antenna. The radiating structure consists of a square patch with embedding four bent slots to reduce the overall dimensions. Circular polarization is obtained by feeding the patch with 90° phase shift between two pins placed symmetrically on the two main axes.

Microstrip array antenna for fire-detection applications
2007 IEEE Antennas and Propagation Society International Symposium, 2007AbstractIn this paper, a first investigation on critical issues for a fire‐detection ground‐based Ku‐band radiometer antenna design is addressed. A printed technology with standard dielectrics has been employed, to reach low cost, simplicity in realization, and easy integrability with the electronic front‐end.
