Language: English Typology: 1.01 - Original Scientific Article Organization: MIDEM - Society for Microelectronics, Electronic Components and Materials Abstract: A dual-band, single-layer reflect array offering high gain has been developed for dual-polarized drone tracking applications. The reflect array unit comprises two center-notched spiral structures aligned orthogonally and is separated by an independent notchperfect rectangle element. Based on the reflect array unit design, a single layer 7 x 7 array, totally 49 elements for Horizontally Linearly Polarized (HLP) Ku-band transmission (12.4 – 14.8 GHz) and 49 elements for Vertically Linearly Polarized (VLP) X-band reception (10.7 – 12 GHz is designed with the phase changes of over 75o . This phase changes is obtained by adjusting the length of the notched spiral patch within the unit cell. Two distinct horn sources has been implemented to energize the orthogonal ports, supplying separate linear polarization for each frequency band. The efficiency is about 18.2 to 22% across different frequency bands, underscoring the array’s suitability for Drone Tracking applications. From the performance measures, it is found that the proposed dual-band reflect array is more suitable for drone ground station tracking applications. Additionally, this proposed structure minimizes design complexity and meets specifications of a low profile antenna with a simple structure and reduced weight.

Title:	Dvopasovni odsevni niz za oddajnik/sprejemnik zemeljske postaje za sledenje dronov
Abstract:	Razvit je bil dvopasovni enoslojni odbojni niz z visokim ojačenjem za dvo-polarizirane aplikacije sledenja dronov. Enota odbojnega polja je sestavljena iz dveh spiralnih struktur s središčnim zarezovanjem, ki sta pravokotno poravnani, ločuje ju neodvisni pravokotni element s popolnim zarezovanjem. Na podlagi zasnove enote odbojnega polja je zasnovano enoslojno polje 7 x 7, ki ima 49 elementov za oddajanje v pasu Ku (12,4-14,8 GHz) in 49 elementov za sprejemanje v pasu X (10,7-12 GHz) z vertikalno linearno polarizacijo (VLP) s faznimi spremembami nad 75o . Te spremembe faze se dosežejo s prilagajanjem dolžine spiralne zaplate z zarezami v enoti celice. Za napajanje ortogonalnih vrat sta bila uporabljena dva različna rogova, ki zagotavljata ločeno linearno polarizacijo za vsak frekvenčni pas. Učinkovitost je približno 18,2 do 22 % v različnih frekvenčnih pasovih, kar poudarja primernost polja za aplikacije sledenja dronov. Iz meritev učinkovitosti je razvidno, da je predlagano dvopasovno odbojno polje primernejše za aplikacije sledenja zemeljskih postaj dronov. Poleg tega ta predlagana struktura zmanjšuje zapletenost zasnove in izpolnjuje specifikacije nizkoprofilne antene z enostavno strukturo in manjšo maso.
