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 BROADBAND CIRCULARLY POLARIZED DIELECTRIC RESONATOR ANTENNA ... the work in [18], a broadband CP cylindrical DRA with annular slot excitation is investigated here. Figure 1 shows the geometry of the proposed antenna. The cylindrical DR has a radius of a = 5mm, a height of d = 12mm and a relative permittivity "d = 10:2. The DR is positioned on top of the substrate. An annular slot and an L-shaped microstrip ... 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 ...

US20110273351A1 - Wideband cavity-backed slot antenna ... A wideband cavity-backed slot antenna includes an enclosure having a slot, a balun located proximate the slot, a feed extending through the enclosure to the balun, and a plurality of coupled lines proximate the balun and distal to a location at which the balun is coupled to the feed. 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.
