A microstrip array feed for MSAT spacecraft reflector antenna [PDF]
An L-band circularly polarized microstrip array antenna with relatively wide bandwidth has been developed. The array has seven subarrays which form a single cluster as part of a large overlapping cluster reflector feed array.

A Broadband Bow-Tie Cavity-Backed Slot for Traveling-Wave Arrays in the Millimeter-Wave Band [PDF]
, 2019 The use of bow-tie geometries to enhance the characteristics of a radiating element previously proposed by the authors is presented. The previous element consisted of a broadband cavity-backed slot in transmission configuration. The bow-tie shape of the

Feeding‐line‐based decoupling patch antennas
IET Microwaves, Antennas & PropagationMutual coupling among multiple antennas has been a problem needed to be tackled in multiple‐input‐multiple‐output (MIMO) systems. A decoupling method based on short decoupling feeding lines (DFLs) for MIMO patch antennas is proposed.

Modeling of microstrip antenna arrays
, 1994 A new model is developed form the " element by element" approach. It consists in a decomposition in sub-arrays in order to reduce the time of calculation in the modeling of finite arrays. In this modeling we consider that the surface currents are identical on patches which have same neighbourhood configuration.
