Antenna Theory Slot ... The radiation pattern of the Slot antenna is Omni-directional, just like a half-wave dipole antenna. Take a look at the following illustration.
Chapter 8 Slot Antennas - eetrend.com The electric field is everywhere normal to the surface of the slot antenna except in the region of the slot itself. The theoretical analysis of this configuration shows that the radiation of the currents in the sheet can be deduced directly from the distribution of the electric field in the slot. Slot Antenna - an overview | ScienceDirect Topics The small slot antenna has E ϕ and H θ radiation fields, in contrast with the E θ and H ϕ radiation fields of its complementary small dipole antenna. Similar procedures can be extended to a half-wave slot antenna or, in general, to a rectangular slot antenna of any arbitrary length. PRINCIPLES OF ANTENNA RADIATION - tpub.com PRINCIPLES OF ANTENNA RADIATION After an rf signal has been generated in a transmitter, some means must be used to radiate this signal through space to a receiver. The device that does this job is the antenna. The transmitter signal energy is sent into space by a TRANSMITTING ANTENNA; the rf signal is then picked up from space by a RECEIVING
The antenna works at around 5.5 GHz and has a nearly 3.1% 3 dB axial ratio bandwidth. In , polarization reconfiguration metasurface is rotated to realize 4% 3 dB axial ratio bandwidth in both RHCP and LHCP states. In this paper, a reconfigurable slot antenna with a simple structure is presented.
