The antenna is fabricated on an FR4 substrate with a permittivity of 4.6, and a thickness of … WebbAdditionally ground is defected to enhance the bandwidth and further size is reduced. Material FR-4 (εr = 4.4)has been chosen to design proposed antenna and substrate thickness as 1.59 mm. Microstrip feed technique is used as it provides better results.
WebbThe reduction in hatching probability was significant ( G -test of independence: Gadj = 5.67, 1 df; P = 0.017). Fifteen of 100 control nests had at least one unhatched egg, and 10 of 24 nests with cameras failed to hatch at least one egg ( Gadj = 7.24, 1 df; P < 0.01). Webb28 okt. 2024 · Many techniques have been developed to increase the impedance bandwidth, including adopting the known stacked patches [ 37 ], parasitic resonators [ 38 ], and capacitive coupling feed [ 39, 40 ]. It is still challenging to obtain a wider bandwidth, since the main solution uses a thick and/or low dielectric constant substrate.
WebbThe shorted microstrip patch antenna is a compact antenna but it suffers from the disadvantage that more number of shorting pins is required thereby making fabrication process harder especially when manufactured in larger quantities. ... “Size reduction technique for shorted patches,” Electronics Letters, Vol. 35, pp. 948-949, 1999.
