6th European Microwave Conference, 1976, 1976
An equivalent network for rectangular shaped microstrip radiating elements is derived. In order to simplify the problem the radiating elements are considered as two slots separated by a transmission line of low characteristic impedance. The slots are characterized by their equivalent admittances.

A 24GHz microstrip array antenna
Proceedings of 2011 International Conference on Computer Science and Network Technology, 2011A 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.

Broadband microstrip array antenna
1980 Antennas and Propagation Society International Symposium, 1980A broadband (13%) microstrip array antenna with high efficiency, low cost and low weight has been designed and evaluated. The antenna is foam supported and is about 0.15 \lambda thick. The feeding is accomplished by a separate microstrip network. This antenna is compared with two dielectric loaded microstrip antennas, one with a separate stripline feed

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.

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.

Broadband microstrip array antennas
Proceedings of IEEE Antennas and Propagation Society International Symposium and URSI National Radio Science Meeting, 2002Microstrip 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.

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-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
