“…Such antennas can be used as the feeds for reflector antennas operating with two orthogonal polarizations (see, for example, [2]). Using the presented EDITFEKO card macro it is also possible to design LPDA feed sim ultaneously with a reflector antenna with the usage of MoM or MoM-physical optics hybrid method.…”

The proposed report notes the perspective of using programming features provided by modern commercial electro magnetic software packages to automate and accelerate the process of designing of complex multi-element microwave structures. Two macros coded for log-periodic dipole array antennas (LPOAs) designing in popular software tools FEKO and CST Microwave Studio are presented and discussed. These macros are able to create the fully parameterized models of multi-element log-periodic antenna struc tures including determination of mesh setting, material properties, boundary conditions, field monitors, and other project settings. Two example designs of LPOAs are shown. One of them is the simple L-band LPOA operating at the frequency range from 0.9 GHz to 1.5 GHz. Another one is the decade bandwidth planar LPOA feed for a reflector antenna with FlO ratio of 0.55 that consists of 47 dipoles. nporpAMM�POBAH�E MAKPOCOB B COBPEMEHHblX npOrPAMMHblX KOMnIlEKCAX 3IlEKTPO.Q�HAM�4ECKOrO MO.QEIl�POBAH�fI HA np�MEPE npOEKT�POBAH�fI IlOrOnEP�O.Q�4ECK�X B�6PATOPHbIX AHTEHH nnaCTI!1KOB A.

“…While printed planar LPDAs offer several advantages, nonplanar LPDAs have been used as reflector feed for various applications in order to provide higher gain with an axially symmetric radiation pattern which is necessary for optimum illumination of reflectors [15,16]. The most promising recent application is the next generation of astronomy telescopes such as square kilometre array (SKA) and Allan telescope array (ATA) for which various non-planar dual polarised LPDA designs have been reported [17][18][19].…”

An efficient and low cost approach to realise a non-planar dual-polarised log-periodic dipole array antenna (LPDA) using printed circuit board technology is proposed which achieves a high bandwidth and operational frequency. The proposed antenna utilises a very short transition from a coaxial cable to a balanced four-conductor transmission line to realise an ultrawide bandwidth balun and input impedance matching. An analysis of the utilised four-conductor transmission line alongside its comparison to two-conductor transmission line of a planar LPDA is also presented. Two prototypes of the antenna operating over the frequency ranges of 1-13 GHz and 1-18 GHz were designed, fabricated, and tested. An average gain of 6.7 dBi is obtained. Measured voltage standing wave ratio, cross-polarisation and front-to-back ratio of both prototypes are better than 2.6, −14, and 22 dB respectively.
