Here an hexagonal printed antenna is reported. The antenna has measurement volume of 800 mm 3 . It operates at the frequencies 2.9 GHz, and 6.3 GHz with S11 of -10.17 dB and -14.49dB respectively. It has produced acceptable gain of 2.065dB for 2.9 GHz and 3.45dB for 6.3 GHz. The frequencies obtained are useful for aeronautical radio location and satellite applications. The antenna is designed using HFSS software and tested using ZVH vector network analyzer.

New microstrip antenna initiated from the portions of  1st order structures of Sierpinski square geometry is  modeled  in this paper as quasi-fractal device using an FR4 substrate of 4.4 dielectric constant, 1.6 mm thickness and 0.02 loss tangent. The intended microstrip antenna is designed for band frequencies  of 3.5 and 7.8 GHz for WiMAX and metrological satellite applications with a bandwidth of 0.66 and 0.78 GHz for each band respectively. The designed antenna has considerable compact size  that is smaller than many reported fractal and non-fractal antenna structures in the literature. Also, it has interesting return loss and radiation results that can be employed in diverse wireless devices. Measured input reflection coefficient, radiation patterns and gain results have been found in good agreement with those predicted by simulations.

This paper presents an original elliptical microstrip patch antenna is proposed for Ku/K band satellite applications. The proposed antenna has a simple structure, small size with dimensions of about 10×12×1.58 mm³. The antenna has been designed and simulated on an FR4 substrate with dielectric constant 4.4 and thickness of 1.58 mm. The design is simulated by two different electromagnetic solvers. The results from the measured data show that the antenna has two resonant frequencies that define 2 bandwidths, defined by a return loss of less than -10 dB, and are: (14.44 GHz, 829 MHz) and (21.05 GHz, 5126 MHz),with the gain 5.59 dB and 5.048 dB respectively. The proposed antenna can be used in many applications such as in satellite, and wireless communications.
