Therefore, a fourth antenna type with tuneable-notched bands was designed by adding a varactor diode at an appropriate location within the slot. Microsoft Word - str_0998-1005 However, in [20], [25], PIN diodes connected on a microstrip slot antenna are used to achieve the purpose of reconfigurable band notching. Radioengineering - June 2017, Volume 26, Number 2 [DOI: 10… A broad-band balun is designed and integrated with the antenna handset in order to provide the feeding network and perform the measurements of the antenna radiation performance.

This paper proposes a dual-band reconfigurable square-ring antenna with a polarization diversity property. The proposed antenna consists of a square-ring resonator, two stubs with a shorting via, and two PIN diodes. The stub is positioned symmetrically to the left and right of the square-ring resonator, and the square-ring antenna connected to one of two stubs has a dual-band resonance.
radiation of the antenna is generated by two orthogonal modes at a same resonant frequency,the frequency offset phenomenon which often happened to antennas with switchable polarization can be avoided.

A Novel Reconfigurable Microstrip Antenna With Switchable
By using such a structure, a reconfigurable antenna with a switchable polarization in a dual band can be realized. As mentioned in , as the position of the stub changes, the first resonant frequency does not change, but the second resonant frequency is affected.

A novel reconfigurable ring‐slot antenna with switchable polarization and frequency agility is presented. Circular polarization (CP) radiation of the proposed antenna is achieved by introducing proper asymmetry in the ring‐slot structure and feeding the ring slot using a microstrip line at 45° from the introduced asymmetry.
