Resonant conductance of inclined slots in the narrow wall of a rectangular waveguide

Abstract

Abstruct-A method to determine the admittance and resonant length of an inclined slot in the narrow wall of a fectangular waveguide is presented. An expression for the admittance of the slot is. derived nsing an angolar spectrum of plane.waves and the discontinuity in modal current. When the depth of cut in the top and bottom wall is assumed to be zero, the expression for resonant conductance found by the present method is exactly the sameas that obtained by Stevenson. Comparison' between the theoretical and experimental results on the variatiun of resonant conductance with angle of inclination of Slots for a fixed depth of cot of 3.5 mm is presented. ' <

“…Untuk memvalidasi lebih lanjut, hasil perhitungan juga dibandingkan dengan hasil pengukuran pada [16]. Agar dapat dibandingkan, digunakan dimensi dan variasi yang sama, dalam hal ini digunakan parameter antena sama dengan perhitungan sebelumnya dengan menetapkan panjang bagian pada sisi atas dan bawah sebesar ∆ = 3,5 mm serta dengan sudut kemiringan berkisar antara 5 o sampai dengan 45 o .…”

Analysis of an Inclined Semi-Circular Slot in the Narrow Wall of a Rectangular Waveguide

“…The edge slots have been investigated with various methods [6][7][8][9][10][11][12][13][14][15]. Hashemi-Yeganeh and Elliott [16] analyzed untilted edge slots excited by tilted wires in a rectangular waveguide.…”

Efficient moment method analysis of a rectilinear edge-slot radiator in rectangular waveguide

“…Of the range of slot geometries which can be employed in such arrays, the inclined edge slot represents possibly the most widely studied (Watson 1946, Stevenson 1948, Das et al 1984, Hsu and Chen 1989, Jan et al 1991, 1994, Ahn 1992. When the height of the rectangular waveguide is less than ¶=2 (the resonant slot length), resonant slots of moderate inclination angle cannot be realized without some portion of the slot encroaching into the broad wall of the waveguide.…”
