Microstrip fed annular slot antenna

Axial-Ratio-Bandwidth Enhancement of a Microstrip-Line-Fed ... Abstract: The design of a new microstrip-line-fed wideband circularly polarized (CP) annular-ring slot antenna (ARSA) is proposed. Compared with existing ring slot antennas, the ARSAs designed here possess much larger CP bandwidths. US4547779A - Annular slot antenna - Google Patents

antenna based on a concentric annular- rings microstrip fed by four apertures is designed. The broadband feed network based on the broadband phase shifter presented in [10] and [11] is used to obtain the required phase shift, thus allowing improvement of the axial ratio in the direction of maximum radiation. This antenna could be On the Use of Slots in the Design of Patch Antennas Annular gap probe compensation ... The U-slot patch The L-probe fed patch ... popular wideband microstrip antenna.

A modified microstrip line fed compact UWB antenna for WiMAX ... The antenna consists of a rectangular patch of dimension L p × W p. A tapered microstrip line with annular sector at the top is used which modifies the feed line as spanner shape. The modified spanner shaped microstrip line terminates with rectangular patch whose lower left edge is etched with a rectangular slot of dimensions L p1 × W p1. Microstrip-Fed Dual-Frequency Annular-Slot Antenna Loaded by ... annular-split-ring by a narrow rectangular slot. The slot antenna is fed by a stepped microstrip line, which provides impedance matching. Usually, the resonant frequencies are mainly determined by the circumference length of the annular-slot. For the proposed annular-slot antenna, the first mode is mainly determined by the circumference of Aperture Coupled Microstrip Antenna Design and Analysis
