A Dual-Band Slot-Embedded Microstrip Antenna for Dual-Polarization Operation Muhammad Asad Rahman*, Eisuke Nishiyama, and Ichihiko Toyoda Abstract—In this study, a new slot embedded microstrip antenna for dual-band dual-polarization operation is proposed. The antenna comprises a single layer structure with a square radiating patch Analysis of U-slot loaded Patch for Dualband Operation proposed to provide dual band operation such as radial slot antenna [3], rectangular microstrip slot antenna with a π-shaped slot [4], and hybrid dielectric resonator antenna [5]. The reactively loaded antenna is one of the popular techniques to obtain the dual band operation. Dual resonance is obtained by introducing the slots parallel to the N93-27751 Slot-line end-fire antennas for THz frequencies

Slot Loaded Square Microstrip Patch Antenna for Dual Band ... Slot Loaded Square Microstrip Patch Antenna for Dual Band Operation. Faria Jaheen1,*, Abdullah Al Noman Ovi. 2, Marjan Akhi. 3. 1. Department of Electrical & Electronics Engineering, American International University-Bangladesh, Dhaka, Bangladesh . 2. Department of Electrical & Electronics Engineering, Faculty of Engineering, Slot Antenna - an overview | ScienceDirect Topics The slot antenna, consisting of a narrow slit in a ground plane, is a very versatile antenna. With modification, it is amenable to waveguide, coplanar waveguide (CPW), coaxial, slot line, or microstrip feeding schemes and has been used in all aspects of wireless and radar applications. SLOT-FED SWITCHED PATCH ANTENNA FOR MULTI- PLE FREQUENCY ... Abstract|A switchable microstrip patch antenna for multi-frequency operation is presented. The antenna is fed by a coplanar waveguide via capacitive coupling slot. The antenna allows easy reconflgurability of the frequency band of operation by incorporating switches in the coupling slot. The resonant frequency of the antenna can be adjusted A Review of Aperture Coupled Microstrip Antennas: History ...
Slot antennas are used typically at frequencies between 300 MHz and 24 GHz. The slot antenna is popular because they can be cut out of whatever surface they are to be mounted on, and have radiation patterns that are roughly omnidirectional (similar to a linear wire antenna, as we'll see). The polarization of the slot antenna is linear.
Antenna (radio) - Wikipedia In reception, an antenna intercepts some of the power of a radio wave in order to produce an electric current at its terminals, that is applied to a receiver to be amplified. Dual-band blade antenna - Wikipedia Dual-Band Blade Antenna, a type of commercial RF "Blade antenna" that uses a "plane and slot design" to get efficient omni-directional coverage at two distinctly different RF bands.

Antennas: The Slotted Waveguide Antenna An example of a slotted waveguide array is shown in Figure 1 (dimensions given by length a and width b) Figure 1. Basic geometry of a slotted waveguide antenna. As in the cavity-backed slot antenna, each slot could be independently fed with a voltage source across the slot. However, (especially for large arrays) this would be very difficult to ... A novel approach for miniaturization of slot antennas ... A slot antenna whose radiating slot segment is of a length , should be terminated by a reactance given by (2) in order to maintain the magnetic current distribution of a resonant slot antenna (see Fig. 2). In (2) (3) and and are the characteristic impedance and the guided wavelength of the slotline, respectively.
