Design of ultra wideband trapezoidal shape slot antenna with circular polarization

A Dual Band Fractal Slot Antenna Loaded With Jerusalem Crosses for Wireless and Wimax Communications

“…In addition, slot antennas are suitable for achieving circular polarization which has been studied in some researches with slot feeds parameter tuning [12,13]. Microstrip compact slot antennas for wireless application are one of the slot antenna types that have been designed by some techniques such as slot rings, parasitic elements, and L and U shape slots [14,15].…”

The comparative study of bulk magneto-phonon and magnetic polaritons of lateral antiferromagnetic superlattices for potential THz applications

“…Currently, in order to obtain high performance antenna, two common methods can be adopted. One is to design meticulously shape of the antenna [1][2][3][4][5], the other is to implant certain photonic crystals in substrate layer, which will enhance workability of the antenna because of the forbidden bands of photonic crystals may suppress the leaky waves [6]. Certainly, the optimal solution for researchers has been to combine these two approaches [5].…”

“…It is universally acknowledged that the bulk MPPS spectra will provide detailed information on the properties of AF superlattice such as photonic band gaps, which may make the performance of some THz devices optimized. Besides that, exploitation of polariton electromagnetic wave behavior offers a direct channel of 4 control over propagation and dispersion of not only electromagnetic but also lattice vibrational coherence and energy. Therefore, it deserves careful study.…”

A novel CPW-fed wideband printed monopole antenna with DGS

“…Wang et al [11] proposed a CPW-fed open-slot antenna for multiple wireless communication systems. Krishna et al [12] designed the ultra wideband trapezoidal shape slot antenna with circular polarization. Ramin et al [13] presented a novel single-layer dual band-notched printed circle-like slot antenna.…”
