In this study, a unique design in frequency reconfigurable antenna approach is proposed .The shown design in this paper can be used for Ku band downlink especially in satellites. A special em ployment includes a rectangular slot with four PIN diodes where the frequency reconfigurability is obtained. A quad-polarization and frequency reconfigurable square Fig. 1 shows the geometry of proposed quad polarization and frequency reconfigurable antenna with detailed dimensions. It consists of a square patch of side a printed on RT Duroid substrate of ε r = 2.2 and thickness h = 3.2 mm. At the two RF ports an impedance transformer matches the 50 Ω feed line to the patch.Fig. 1(a) shows a square ring slot with outer dimensions l × w etched in the Frequency Reconflgurable Microstrip Patch-Slot Antenna … switches are placed in the slot. The antenna is capable to reconflgure up to six difierent frequency bands from 1.7GHz to 3.5GHz. The microstrip patch antenna produces three difierent frequency bands with directional radiation pattern while the microstrip slot antenna produces another three frequency bands with bidirectional radiation pattern.

elements of the antenna, thus resulting in a beam-reconfigurable antenna that can switch the radiation pattern to a different direction. This study focuses on a frequency-reconfigurable antenna that is designed into a multilayer structure (stacked patch) with considerably higher gain. Moreover, a new coupling method is A Frequency Reconfigurable Rotatable Antenna Design for ... front end design is the design of reconfigurable antenna. A reconfigurable antenna is essential to sense the entire spectrum of interest and to minimize interference and multipath problems within several frequency bands. Some of the recent works have been implemented using PIN diodes, RF-MEMS or laser diodes [3-5]. Slot antenna - Wikipedia
