## Abstract In this paper, a robust low‐cost 4×4 microstrip antenna array is designed to be used in wireless communications systems working between 3.4 and 3.6 GHz. A foam substrate, together with a set of parasitic patches in two geometrical configurations, has been used to enhance its bandwidth.

## Abstract In this paper, the characteristics of a modified meander‐type antenna for broadband impedance bandwidth are investigated in the 5‐GHz band. The design is based on a modified meander‐line width in a finite‐sized ground with coaxial SMA feeding. The modified meander‐type microstrip patch
The (3,3) and (4,4) bands of the 2 has been studied using the velocity modulation technique in the near-infrared region. The rotational structure has been analyzed by the method of combination differences in conjuction with the standard Hamiltonian. Molecular parameters and rotational temperatures
