Microstrip‐line‐fed printed shorted ring‐slot antennas for ... 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 microstrip line 90° to the shorted section.

Monopole Antenna - an overview | ScienceDirect Topics It is based on a broadband eccentric annular monopole antenna connected to a delay line. The delay line length L is chosen to separate the structural and tag modes with a round-trip delay of about 1 ns. Two slots between the antenna ground plane and the circuitry have been introduced, as explained in section 2.5.2. Broadband Circularly Polarized Annular-Ring Microstrip ...

Ultra-Wide-Band Microstrip Concentric Annular Ring Antenna ... 2. Antenna design Annular ring slot antenna has a reduce sizemore than circular patch antenna and the ultra-wideband characteristic [6]. In this paper, to broaden the bandwidth of annular ring slot antenna, we placed the concentric annular patch inside circular slot and designed the low impedance feed line. ECCENTRIC annular apertures find practical applications ... I. INTRODUCTION E CCENTRIC annular apertures ﬁnd practical applications in waveguide junctions [1], wideband aperture antenna [2], cavity-backed circular patch antenna fed by coaxial line [3], and eccentric coaxial line [4]. Conformal mapping has been exten- sively used to analyze scattering from eccentric annular aper- tures [1], [4]. Antennas - Tech Comm, Inc. Standard DF antenna models are typically broadband antennas covering frequencies across the communications bands from HF through UHF, or approximately 20 MHz to 3000 MHz. The most common design is a cavity backed annular slot that incorporates ferrite elements for the lower HF frequency range. DUAL-BAND BEAM SCANNING REFLECTARRAYS AND NOVEL WIDEBAND AND ...
