Array-antenna Decoupling Surface for Dual-band Microstrip Antenna Array
2020 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2020A compact Array-antenna Decoupling Surface (ADS) is presented to decouple dual-band microstrip antenna array, working at 4.5GHz and 5.6GHz. Through diffracting part of the radiated waves to cancel the coupled ones, ADS can greatly reduce the mutual coupling of 10dB and 20.4dB at two frequencies between array elements.

Tilted beam microstrip array antenna
2017 IEEE International Conference on Signal Processing, Informatics, Communication and Energy Systems (SPICES), 2017Tilting of broadside radiation pattern of microstrip antenna array is obtained by loading SRR on the ground plane between antenna elements. Progressive Phase Shift method is used here. The phase delay generated by single SRR is around 500 when compared to a reference transmission line.

Microstrip active antennas and arrays
1988., IEEE MTT-S International Microwave Symposium Digest, 2003A description is presented of active antennas and arrays fabricated using microstrip patch antennas and Gunn diodes. Injection-locking experiments were carried out on these X-band antennas to achieve frequency coherency and to calculate the circuit Q-factor. An electronic tuning range of over 9% has been achieved for the single active patch element.

Planar microstrip Yagi array antenna
Digest on Antennas and Propagation Society International Symposium, 2003The Yagi concept is introduced for the planar microstrip array. With parasitic director and reflector patches located on the same plane of the driven element, the beam peak, by the effect of mutual coupling, can be tilted toward the endfire direction. With this capability, the power divider and phase delay transmission lines in a conventional array are

Multi-Layer Microstrip Array Antenna
18th European Microwave Conference, 1988, 1988The bandwidth behaviour of a pair of stacked rectangular patches is investigated experimentally. The return loss is measured as functions of the size of the upper patch and the separation of the patches. The band-width of the optimized stacked antenna is twice as broad as the bandwidth of the single patch with equal height.

Microstrip-CPW transitions for antenna array applications
Microwave and Optical Technology Letters, 1999Coplanar waveguides nowadays are successfully used to feed printed antennas. This technique is very interesting for antenna arrays. However, the complete system involves the association of several microwave functions, essentially power divisions and phase shifts, which are easier to implement in microstrip technology than in CPW technology. In order to

Comparison between microstrip grid array antenna and patch array antenna
2016 IEEE Region 10 Conference (TENCON), 2016In this paper, a microstrip grid array antenna is designed and compared to bandwidth-enhanced patch array antenna. The proposed microstrip grid array antenna has 145 radiating elements which are on a single-layer electrically-thin RT/duroid 5880 substrate.

A Phased Array Antenna using Microstrip Patch Antennas
12th European Microwave Conference, 1982, 1982A phased array antenna using microstrip for tne AMES (Aeronautical Maritime Engineering Satellite) airborne antenna. The phased array antenna has tested over a frequency range from 1.54 to 1.65 GHz. Scanning abilities up to +30 degrees have been verified over above the frequency range. The V.S.W.R is less than 2 to 1 over 8.4 percent bandwidth.
