Q134 Conformal Broadband Antenna - Harris Harris’ Q134 Antenna offers the latest in fully conformal, low RCS antenna. The Q134 antenna capitalizes on Harris’ proven annular-slot technology providing a 3.7:1 operating bandwidth, which exceeds the useful bandwidth of most blades and other exposed apertures. In addition to the broad operating bandwidth, the Q134 also Broadband CPW-Fed Circularly-Polarized Slot Antenna With ...

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 ...

Antenna Performance - an overview | ScienceDirect Topics Based on the same broadband eccentric annular monopole, another design is considered without slots in the ground plane. The tag is based on a square-shaped transmission line that rounds the monopole. The antenna size has been increased to slightly reduce its center frequency. A low-frequency annular-slot antenna - NIST Page A Low-Frequency Annular-Slot Antenna James R. W ait The radiation characteristics of an annular slot cut in an ideally conducting ground plane are discussed. The voltage impressed between the concentric edges is assumed to be constant around the slot. The annular slot is backed by a hemispherical cavity which has A Broadband Multi-layer Dual-polarization Slot Antenna ...
