A modified slot dipole antenna fed by a coplanar waveguide for dual-frequency operation is presented. This antenna is formed by placing an additional slot dipole parallel to the coplanar waveguide-fed inductive slot dipole antenna, and inserting between them a pair of slot apertures shorter than the two slot dipoles. How does a slot antenna work? - Stack Exchange Perhaps most of the slot antennas of this type are undesired, such as interruptions in the ground plane of a PCB, or undesired holes in something that should be acting as a shield. For slots that are made to be intentional antennas, they are usually slots in a waveguide or a box. Of course this changes the radiation pattern and the impedance ...

What is the difference between slot antenna and patch
For the lower frequency band, a V-slot is loaded on the planar dipole for acting as a capacitive loading for having wide impedance matching of the antenna. Then, two additional smaller planar dipoles are placed and connected to the irregular short patch for achieving another wideband performance at the higher frequency band. Dual frequency, dual polarized, multi-layered microstrip slot ... Dual frequency, dual polarized, multi-layered microstrip slot and dipole array antenna Dec 3, 1992 - California Institute of Technology An antenna array system is disclosed which uses subarrays of slots and subarrays of dipoles on separate planes. Tuning a Dual-Band Bowtie Slot Antenna with Parabolic ... Tuning a Dual-Band Bowtie Slot Antenna with Parabolic Radiating Slots for the 900 MHz and 2400 MHz Bands Layne A. Berge ∗,Michael T. Reich Masud A. Aziz†, Benjamin D. Braaten† ∗Center for Nanoscale Science and Engineering, North Dakota State University 1805 Research Park Dr. Fargo, ND 58102 USA DIPOLE ANTENNAS | Electronics World where Zs is the impedance of the slot and Za is the impedance of the dual linear antenna. Cavity-backed slot antennas with integrated matching networks are among the smallest (physical size/electrical size) antennas available (7). Biconical Dipoles. A biconical dipole, such as shown in Fig. 7a, is commonly used for broadband applications.

One way to create a dual band blade antenna is to create a slot in a blade antenna that is less than or on the order of so that the lower frequency does not 'see' the slot (it is a rule of thumb that the perturbation created by a discontinuity less than on a structure is negligible). dual band dipole antenna | eBay Find great deals on eBay for dual band dipole antenna.
