## Abstract Frequency tunable annularβring slot antennas with circularly polarization (CP) operation are studied in this article. The annularβring slot antenna operates at one fullβwavelength resonant mode and it is excited by an Lβshaped coupling strip with a reactive loading. It is found that the

## Abstract This study proposes the concept of frequency tuning for an electrically small antenna to be used in wideband applications in low frequencies. An electrically small antenna has too narrow bandwidth to be utilized for wideband systems. However, in such mobile TV services that the band is
## Abstract In this article a wide bandwidth frequency reconfigurable antenna is presented. The basic geometry of the antenna is a microstripβfed bowβtie slot antenna. This type of antenna allows bandwidth to increase and it is modified to mount switches easily as well as to maintain good impedance
