Compact design of monopole antenna for SWB application with high BDR

Abstract

In this paper, a simple and compact monopole antenna with a high bandwidth ratio (BDR) of around is investigated for super wideband (SWB) applications. Using an F4B substrate with a dielectric constant of 2.65, loss tangent of 0.002, and connecting it to a triangular tapered 50‐Ohm line, the suggested antenna achieves its performance objectives. The proposed antenna has an electrical dimension of 0.14λ × 0.22λ and spans the SWB frequency range of 2.89–60 GHz with a 181.5% fractional bandwidth and reflection coefficient S11 < −10 dB. It has been revealed that the results of both experiments and simulations are remarkably similar to one another in terms of their conclusions. In comparison to other SWB antennas, the suggested antenna has a greater BDR, a larger bandwidth, and a more compact size. Apart from that, the antenna has good gain and good radiation characteristics over the whole operational frequency range.

Narrow and wide band monopole antenna design using heterogeneous bidirectional recurrent neural network for LTE and UWB applications

“…When a reverse voltage is applied, the depletion regions width in the diode changes leading to variations in capacitance. This voltage‐dependent capacitance is the basis for differentiating both diodes 24–27 . Numerous methods have been widely scrutinized to attain multiband along with ultrawideband characteristics by using a radiator like loop shape, ellipsoid, circle, semicircle rectangle, triangle, spiral, or square 14 antenna 28–30 …”
