A novel foot‐shaped elliptically embedded patch‐ultra wide band antenna with quadruple band notch characteristics verified by characteristic mode analysis

Abstract

A novel foot-shaped elliptically embedded patch (EEP) ultra wide band (UWB) antenna with four band elimination features is demonstrated. The designed antenna incorporates embedded ellipses as its structure, a 50 Ω microstrip line feed, and a defective rectangular ground structure (DRGS). The antenna has 22 Â 32 mm 2 in size, with a frequency spectrum of 2.8-13.3 GHz, and a frac-

A high bandwidth dimension ratio compact super wide band-flower slotted microstrip patch antenna for millimeter wireless applications

“…This paper details the design and fabrication of a monopole SWB-FSMPA with a RB-DGS, which is able to transmit signals from 3.78 to 109.8 GHz. The merits of the SWB-FSMPA are: a tiny size of (16 × 22 mm 2 ), a novel flower slot structure, a wide spectrum of 3.78–109.86 GHz, fractional bandwidth of 186 %, BR of 29.1:1, BDR of 5284, peak efficiency of 93.3 %, GD of <0.48 ns, and a linear type phase that proves to be a better contender for millimeter wave applications [ 16 ].…”

“…Some of the evolutionary algorithms include Genetic algorithm, Simulated annealing, PSO (Particle Swam Optimization) which optimize the antenna using natural or collective behavior of the variables. They are not frequently used as they are inefficient with the increase of design variables [25][26][27][28][29]. However, gradient based algorithms such as Quasi Newton Optimizer can handle for large no.…”
