Patch Loading Circular Aperture Slot Antennas for ... This paper proposes a new and simple design for a broadband planar antenna with bi- and uni-directional radiation for WLAN applications. The broadband operation is realized by loading a patch into a circular aperture slot, which is fed by a micostrip line on the other side of the slot.

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]. In this letter, we shall consider an electrostatic po-tential penetration into an eccentric annular aperture in a thick conducting plane.
BROADBAND CIRCULARLY POLARIZED DIELECTRIC RESONATOR ... 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 ... 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 ...

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.

Simulated normalized radiation patterns on the x-y plane with a short stubs are on the bottom and the annular slot antenna is on the top side of the circuit at 225 . The null direction for the slot without any short would be in the substrate.
