A novel 5.8GHz quasi-lumped element resonator antenna

Analysis of the Proximity Coupling of a Planar Array Quasi-Lumped Element Resonator Antenna Based on Four Excitation Sources

“…(2) as stated in [8][9][10][11][12][13], and more specifically in Eq. (1) of [7] where I L is the inductor length, W 1 is the inductor width, and t is the metal thickness as shown in Figure 1(b).…”

“…In this work a moderate dielectric constant was used and the equation to determine the IDC of the resonator was stated by Avenhaus in [6] and also appropriately stated in Eq. (2) of [7] for the same design specifications and considerations, where N is the number of fingers, C L is the overlap length of IDC fingers, and Δ = 0.5(w eff − w 1 ) (which is equal to 0.5 for this design) is the correction factor due to the effect of fringing field. The Q-factor of an inductor depends directly on the inductance, whereas the inductor is a single narrow straight inductor shorted across the IDC as shown in Figure 1(a).…”

“…(7) of [7] and it's dependent on, the inductor strip L, the capacitive inductance from the IDC (the length of the finger, the line width of the finger), and the pad capacitances, C p where C is the IDC defined by Eq. (2) of [7], and L is the strip inductance defined by Eq. (1) of [7].…”

“…(2) of [7], and L is the strip inductance defined by Eq. (1) of [7]. C p1 = C p2 are pad capacitances defined by Eq.…”

“…C p1 = C p2 are pad capacitances defined by Eq. (6) of [7], and are formed between the gaps and the ground. The equation to determine the pad capacitance is also stated similarly in [13] where is the resonator length, and h is the substrate thickness.…”
