AB  - printed antenna array consisting of 10 wide-band symmetrical pentagonal dipoles is presented. The feed network of impedance transformers is employed to provide appropriate amplitude and phase distribution necessary to obtain flat top beam pattern. The measured results demonstrate excellent radiation characteristics including 38 degrees flat gain region with maximum ripple of 3.5 dB at the centre frequency. Furthermore, the proposed antenna that is placed in corner reflector with angle of 60 degrees has good gain (17 dBi) and side lobe suppression (18.9 dB). Although it is designed at the centre frequency f(c) = 12 GHz, it was shown to be capable of shaping a good flat top radiation pattern within a fractional bandwidth at least 6% of centre frequency. Also, proposed antenna features cheap, simple and easy fabrication that makes it suitable for mass production.

AB  - Circularly polarized antenna with a possibility of tuning the elevation angle i.e. obtaining maximum radiation in either broadside or directions declined from the zenith is presented in the paper. The antenna consists of a pair of printed crossed dipoles, feed line and gear mechanism for adjusting the height of the antenna in regard to vehicle roof, thus enabling maximums in radiation patterns at lower elevation angles. This feature is particularly interesting in communications between mobile objects and satellites. All simulations and optimizations have been carried out using program package WIPL-D and analysis of obtained results proves the validity of presented concept. Simulated gain is between 4.3 dBi and 7.3 dBi, depending on the antenna position; axial ratio (AR) is less than 3 dB in the operational range of frequencies (2%); reflection coefficient S11 is less than -19 dB. Antenna is designed for INMARSAT frequency range.

AB  - A new type of printed millimeter planar antenna with circular polarization for 60-GHz range is proposed. Radiation elements with two open tape rings are arranged in a two-dimensional 8 x 8 antenna array. Feeding is synphase network with tapered symmetrical (balanced) microstrip in the same plane as the radiation elements. The 8 x 8 array is fabricated in the conventional technology. To test reproducibility, three samples are fabricated. Measured S-11 (VSWR), gain, and axial ratio (AR) are very good and in very good agreement between all three samples: AR  LT  3 dB about 25% and gain near 20 dBi.
