A comparative analysis of various reconfigurable and multiband antenna concepts is
presented. In order to satisfy the requirements for the advanced systems used in modern …

A frequency-reconfigurable slot-ring antenna switching between L-and C-bands is
presented. The aperture of an L-band slot-ring antenna can be reconfigured to a 2× 2 C …

A frequency reconfigurable phased array element is presented. The operational band of the
single port L/S-band antenna can be selected by modifying the element apertures with pin …

A wideband frequency diversity printed-Yagi antenna array is presented. The operating
band of the single port L-/S-bands antenna element can be selected by changing the states …

Requirement for future wireless communication system is large number of antennas on the
single board for performing multiple functions. This imposes constraints on size, weight …

This paper presents a novel planar antenna with a reconfigurable radiation pattern. The
proposed layout consists of N≥ 2 monospaced planar bowtie antennas selected one by one …

Two-port, dual band antenna element for wide-angle scanning planar phased array is
designed. The antenna element consists of two parts: the annular slot fed by a microstrip line …

In this paper, the design and the experimental validation of a polarization reconfigurable
microstrip phased array is presented. The reconfigurability between the right-handed …

A novel two-port, dual-band square-ring microstrip antenna element for wide-angle
scanning planar phased array is proposed. The two ports are used to operate the antenna …
