Broadband Slotted Coaxial Broadcast Antenna Technology Broadband Slotted Coaxial Broadcast Antenna Technology John L. Schadler Director of Antenna Development Dielectric L.L.C. Summary Slotted coaxial antennas have many advantages over traditional broadband panel antennas including much smaller size and wind load, higher reliability and a greater degree of azimuth and elevation pattern Design and Development of an Annular Slot Antenna (ASA) with ... annular slot antenna keeping constant the operation frequency. II. DESIGN CONCEPT The annular slot antenna consists of a circular slot on a square, metal ground plane that is fed by a microstrip line, fabricated on the bottom of the Duroid substrate as can be seen in Figs 1a and 1b.

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. 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]. Four-Port, Broadband, Compact Antenna for 5G Indoor Access ... Abstract: This paper presents a novel four-port, broadband, compact MIMO antenna operating in the sub-6GHz bands of future 5G systems and the 2.45GHz/5GHz WiFi bands. The radiating element topology is inspired from both the Annular Slot Antenna (ASA) and the printed wideband monopole. V-shaped slots are incorporated in the antenna ground for a better efficiency and higher in-plane radiation.
