How is Annular Slot Antenna abbreviated? - TheFreeDictionary In [12], dual-band circularly polarized annular slot antenna is obtained by employing two square slots, a bended microstrip line and a cavity back. As shown in Figure 2(a), antenna 1 is a fold annular slot antenna , and the asymmetric of the slot width will lead to two split orthogonal degenerate modes around 2. Broadband Circularly Polarized Annular-Ring Microstrip Antenna Abstract: A wideband circularly polarized (CP) annular-ring patch antenna with two proximity-coupled L-probe feeds orientated to have phases of 0 deg and 90 deg, using a broadband 90 deg hybrid feed, is proposed. It is found that the current distribution for CP operation can be improved by cutting a smaller concentric circular slot on the ... L annuLar ring SLot MicroStrip antenna for Wideband and MuLti ...

Wideband double-element ring slot antenna N. Behdad and K. Sarabandi A new technique for bandwidth enhancement of microstrip-fed annular ring slot antennas is presented. Using this technique, a wide-band antenna is designed that has consistent radiation parameters across the entire band and has a bandwidth that is six times larger than
The ring is fed by a transmission line in another dielectric layer by means of electromagnetic coupling. The antenna is on a stacked structure consisting of two dielectric layers separated by an air layer in the[20] CHEN J.S.: ‘Triple-frequency annular-ring slot antennas fed by CPW and microstrip line’. Slots and Notch Loaded Rectangular Stacked Microstrip … Staked annular ring microstrip antenna [6] and a dual band slot-loaded patch antenna [7] have been presented. A defected ground microstrip antenna [8] has been reported for 2.4/5.2/5.8 GHz (WLAN applications) and 2.5/3.5/5.5 GHz (WiMAX Applications).
