A simple structure concentric annular-ring slot dual-band circularly polarized (CP) microstrip antenna operating at ISM band (2.45 GHz) and 5G band (3.5 GHz) is proposed in this paper. The antenna achieves dual-band operation by digging two concentric annular-ring slots on the ground. A STUDY OF A COMPACT MICROSTRIP-FED UWB ANTENNA WITH AN OPEN ...

A Broadband Multi-layer Dual-polarization Slot Antenna Based ... Slot antenna, Wideband, Dual-polarization, Differential-feed. Abstract. In this paper, a broadband dual-polarization slot antenna based on differential-feed at X band is proposed. By adopting wide round slots, the antenna inherits a good advantage of broad band. And the multi-layer structure achieves a good isolation between the two ports. In

Compact Microstrip-Fed Annular-Slot Antenna Combined … 2019-5-17 · In this paper, an antenna comprising a compact annular-slot combined with a small concentric annular split-ring slot is presented. The antenna is fed by a T-shaped microstrip line. By using the T-shaped microstrip feedline to tune the level of electromagnetic coupling between annular-slot and feedline, good matching can be achieved. Annular slot antenna - Ball Corporation - Free Patents Online 1991-2-19 · An inexpensive, efficient, broadband, slot-type antenna with unidirectional sensitivity includes a slot-forming means defining a plurality of substantially concentric and generally coplanar annular slots and a non-resonant antenna connection means for transmitting electromagnetic energy to and from the plurality of annular slots.

A Broad-Band Annular-Ring Microstrip Antenna. ... The annular ring may also be somewhat broadband in nature when operated near the TM 12 resonance [5]. ... The small and wideband annular ring slot ... 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 ... Abstract: A wideband circularly polarized (CP) annular-ring patch antenna with two proximity-coupled L-probe feeds orientated to have phases of 0 deg and 90 deg, using a broadband 90 deg hybrid feed, is proposed. It is found that the current distribution for CP operation can be improved by cutting a smaller concentric circular slot on the original larger circular patch to form an annular-ring ...
