Conformal microstrip antennas and microstrip phased arrays
IEEE Transactions on Antennas and Propagation, 1974A new class of antennas using microstrips to form the feed networks and radiators is presented in this communication. These antennas have four distinct advantages: 1) cost, 2) performance, 3) ease of installation, and 4) the low profile conformal design. The application of these antennas is limited to small bandwidths.

Crumpling of Microstrip Antenna Array
IEEE Transactions on Antennas and Propagation, 2013The performance of a 2 × 2 microstrip patch array under crumpling conditions is presented. The antenna array was manufactured on textile material, and three cases of crumpling resembling real applications are discussed. The performance of the individual patch elements correlate with the overall performance of the array. Frequency shifts of up to 6% are

A Filtering Microstrip Antenna Array
IEEE Transactions on Microwave Theory and Techniques, 2011A new filtering microstrip antenna array is presented. The antenna elements, together with the very compact feeding network, function as a third-order bandpass filter. The feeding network, which consists of one power divider and two baluns, provides the first two stages, and the microstrip antenna elements provide the last stage in the filter design ...

Microstrip antenna array for mobile communications
Proceedings of the Sixth International Symposium on Signal Processing and its Applications (Cat.No.01EX467), 2002Several challenges remain however in the development of antenna array for mobile communications and one of these is the availability of efficient radiating elements interfacing with the beamformer. This paper presents therefore a development effort for a novel printed array antenna.

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.

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.

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 ...
