Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

A reconfigurable antenna is proposed for aircraft communication application in the frequency bands of VHF/UHF/L. The aim of this design is to miniaturize the size of antenna to the extent possible and also to enhance its bandwidth. The semi-DGS technique is used to improve the antenna VSWR subsequent to size reduction. The proposed antenna is fabricated on FR4 substrate with dielectric constant 4.4 and thickness of 3.2 mm. One PIN diode is used for reconfiguration capability of antenna. When the PIN-diode is on (ON state), the operating frequency band is 30–230 MHz with gain of 1.5 dBi and when the diode is off (OFF state), the operating frequency band is 420–1560 MHz with the gain of 3 dBi. The VSWR in all the bands is less than two. The measurement results show a good agreement with the simulation results obtained by the fullwave software CST.
