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

The article introduces an ultra-wideband stub-loaded microstrip patch antenna designed for C/X-band applications. The research addresses the challenges of low efficiency, limited bandwidth, and spurious feed radiation in microstrip antennas. By successively loading four patch segments and a square shape stub, the proposed antenna achieves a wide bandwidth of 106.92% (8.11 GHz) and a compact size of 24 mm × 24 mm × 1.6 mm³. The design is optimized using a glass epoxy substrate with a dielectric constant of 4.4, and the antenna is simulated using IE3D software. The article compares the performance of the proposed antenna with other reported designs, highlighting its superior bandwidth and compactness. The research is significant for applications requiring high-frequency, high-gain, and compact antennas, such as WiMAX, WLAN, and other wireless communication systems.
