“…This antenna shows, however, considerable ground plane dimensions, when compared to the size of the radiating part. Some physical modifications to the typical array of dipoles with log-periodic architecture are presented in [15,16]. In [15] a Koch fractal structure is used in the development of the dipole array, allowing for an increase in the bandwidth and reduction of dimensions.…”

“…Some physical modifications to the typical array of dipoles with log-periodic architecture are presented in [15,16]. In [15] a Koch fractal structure is used in the development of the dipole array, allowing for an increase in the bandwidth and reduction of dimensions. This array was designed for the C and S bands, operating between 2.8 and 6.9 GHz, enabling a gain of up to 8 dBi.…”

Modern communication systems require high bandwidth to meet the needs of the huge number of sensors and the growing amount of data consumed, and an exponential growth is expected in the future with the integration of internet of things networks. Spectrum regions in the millimeter waves have aroused new interests, mainly because of the contiguous bands available to meet these needs. In return, and to combat the high losses of propagation in these frequencies, higher gain antennas are needed. This paper describes the use of a logarithmic architecture in the design of microstrip antenna arrays, creating structures with high gain and ultra-wide bandwidth. Three different solutions are presented with five, seven, and nine elements, reaching about 25%, 30%, and 44% of bandwidth, achieving ultra-wideband behavior, efficient and with a compact structure operating at frequencies in around 28 GHz.
