A Novel Concentric Annular-Ring Slot Dual-Band Circularly
A single-feed tri-band circularly polarized dual-annular ... A novel single-feed tri-band circularly polarized (CP) dual-annular slot antenna is presented. The antenna structure is composed of two nonconcentric annular slots fed by a novel inverted h-shaped microstrip line configuration. Compared to most of the previously reported tri-band CP antenna structures, the proposed antenna has low profile ... 《compact and broadband microstrip antenna》.pdf文档全文 ... 211 5.9 Designs with a Bent Tuning Stub 213 5.10 Compact CP Designs with an Inset Microstrip-Line Feed 215 6 Compact ... 10, 162 Annular-ring patch, 177 ...

A new design of a microstrip-line-fed circularly polarized printed ring slot antenna is proposed. Circular polarization (CP) radiation of the proposed design is achieved by introducing proper
analyze the annular ring slot antenna for the TM modes [20]. In this analysis, the feeding line is not considered. Here, we only consider the TM0m modes in the annular ring slot antenna, since only the TM0m modes can produce a monopole like radiation pattern. For the TM0m modes, the fleld inside the structure must be symmetric about the z axis. Microstrip‐line‐fed printed shorted ring‐slot antennas for ... Designs of circularly polarized printed shorted annual and square ring‐slot antennas are proposed. Circular polarization (CP) radiation of the shorted ring‐slot antennas is achieved by selecting a proper length of the shorted section in the ring slot, which is about 3.9 and 8% of the mean circumference of annular and square ring slots, respectively, and feeding the ring slot using a ... Circularly polarized co-designed filtering annular slot ... In this paper, a compact circularly polarized co-designed filtering annular slot antenna (ASA) is proposed. The antenna comprises a distributed capacitor-loaded annular slot radiator to produce circular polarization (CP) radiation, which is seamlessly integrated with a microstripline bandpass filter (BPF) to enhance out-of-CP-band suppression.
