Reconfigurable microstrip stacked array antenna

2016 Online International Conference on Green Engineering and Technologies (IC-GET), 2016
The project examines the novel structure of a frequency-reconfigurable microstrip stacked array antenna by using the aperture-coupled feeding technique and the stacked patch methodology. The aperture slot positions are determined by the bottom patches and top patches (layer 1 & layer 2), respectively.

Microstrip leaky-mode antenna array

IEEE Transactions on Antennas and Propagation, 1997
The first-pass design of a linear eight-element microstrip leaky-mode antenna array is proposed, built, and tested, showing a gain of 18.5 dB, directivity of 23.5 dB, and pencil beam with 3-dB beamwidth (Az/El) of 10.2/spl deg//14.3/spl deg/. Excellent agreement between the theoretical prediction and measured results for the array antenna performance ...

Broadband microstrip array antennas

Proceedings of IEEE Antennas and Propagation Society International Symposium and URSI National Radio Science Meeting, 2002
Microstrip antennas and microstrip arrays have several practical features, which could make them interesting candidates for a lot of antenna applications, ranging from mobile communications to phased array radar systems. The required bandwidth of these applications varies from less then a few percent to 30 percent or more for radar applications.

Microstrip phased array antennas

1973 EIC 11th Electrical Insulation Conference, 1973
High velocity aircraft, missiles, and rockets require conformai, thin antennas. Ideally, an antenna "paper thin" would best suit the aerodynamic and mechanical engineer. This antenna would neither, disturb the aerodynamic flow, nor would it protrude inwardly to disrupt the mechanical structure.

Broadband stacked microstrip antenna arrays

1998 Symposium on Antenna Technology and Applied Electromagnetics, 1998
It is well known that antenna arrays employing single layer microstrip patch radiating elements exhibit inherently narrow bandwidth. The aim of this paper is to investigate the impedance and gain bandwidth characteristics of microstrip antenna arrays with stacked parasitic elements.

A Filtering Microstrip Antenna Array

IEEE Transactions on Microwave Theory and Techniques, 2011
A 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 ...

Conformal microstrip antennas and microstrip phased arrays

IEEE Transactions on Antennas and Propagation, 1974
A 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.

Superimposed dichroic microstrip antenna arrays

IEE Proceedings H Microwaves, Antennas and Propagation, 1988
The dichroic microstrip antenna concept is reported which enables an antenna aperture to function at two widely separated frequencies fH and fL. The innovation centres on the utilisation of printed frequency selective mesh conductors as microstrip patch antennas at fL, which in turn become transparent to near-field radiation at fH, from another ...

A 24GHz microstrip array antenna

Proceedings of 2011 International Conference on Computer Science and Network Technology, 2011
A novel 24GHz microstrip array antenna with 168 rectangular resonators is presented. Compared with the traditional 18×14 microstrip elements array, 84 elements may be reduced with same performance. The feeding network with Dolph-Chebyshev distribution is used for low side lob, and the side lobe of microstrip array antenna is less than −17 dB.

High Efficiency Microstrip Antenna Array

17th European Microwave Conference, 1987, 1987
A fixed beam (broadside) two-dimensional microstrip array of 16×16 resonant rectangular radiating elements at the frequency of 8.15 GHz with a gain of 29.5 dB is presented. A modular approach is utilized in which a given antenna is used as a building block for a higher-gain antenna.
