objective of this work is to design an Annular Ring MicroStrip Antenna (ARMSA) with defected ground structure fed by ... The two annular ring slots are made concentric, centered at C 1 ... The entire setup is placed inside radiation box to avoid leakage of radiation in free space. A Circularly Polarized Annular-ring Patch Antenna with a ... a circularly polarized annular-ring patch antenna embedded in a particular EBG structure and with an unequal cross-slot in the ground plane is studied and presented. This recently proposed annular-ring antenna structure has been shown to be significantly smaller than conventional annular-ring patch antennas, even on standard groundplanes [10]. A single-feed tri-band circularly polarized dual-annular ... In this paper, a single-feed tri-band slot antenna for CP operation using two annular slots fed by an inverted h-shape microstrip line is demonstrated. The frequency ratio of the antenna can be controlled by adjusting the dimensions of two annular slots. In addition, the conical radiation pattern is achieved at the third band.
circularly polarized (CP) radiation, especially only using a single feed. Though some circularly polarized slot antenna designs have been reported, most of these reported antennas are fed by a microstripline [9–11]. The design fed by a CPW [12, 13] is relatively scant. Meanwhile, most of the reported CPW-fed slot …
