The terminal impedance is quite desirable for the radiation. Radiation Pattern. The radiation pattern of the Slot antenna is Omni-directional, just like a half-wave dipole antenna. Take a look at the following illustration. It shows the radiation pattern of Slot antenna drawn in Horizontal and Vertical planes respectively. Advantages
Prof. Girish Kumar - NPTEL Cavity Backed Slot Antenna at 5.8 GHz Slot is cut in the top ground plane. Slot is fed using microstrip line from other side of substrate. Antenna is backed by a metallic cavity for unidirectional coverage d h Cavity Slot Feed Line W Substrate: ε r = 2.55, h = 0.787 mm, tan δ= 0.0015 Slot antenna using HFSS - edaboard.com You should expect to see, in the radiation pattern, everything but what is seen in a half wave dipole. When you add the two radiation patterns you should get very close to a full sphere. What you have works perfectly for a half wave SLOT antenna, not a half wave dipole. You can look at this link for a very brief description. Electronic Warfare and Radar Systems Engineering Handbook

A 28-GHz U-slot Microstrip Patch Antenna for 5G Applications Abstract— In this study, a 28-GHz U-slot rectangular microstrip patch antenna for 5G Applications is proposed. The U-slot antenna concept has been used in patch antenna designed to reduce antenna size.The U-slot patch antenna structure consists of a patch, U-shaped slot, a ground plane and coaxial feed lines. Slot Loaded Square Microstrip Patch Antenna for Dual Band ... With the help of slots near the radiating edges of the patch, the typical microstrip patch antenna can be twisted for. multi-frequency operation. The proposed antenna provides. dual-frequency operation by dint of three rectangular slots. close and par allel to the patch radiating edges. Design of Circular Micro strip Patch Antenna with - ijert.org microstrip antenna,these slots are square rectangula r,cross ,U,H etc.The effect of changing The slot length and width are studied on parameters like gain,return loss, radiation efficiency,antenna efficiency etc.A coaxial probe feed is used at different points by changing the feed locations and their effect are seen on
How can one construct one? What might be the radiation pattern and efficiency compared to a wire antenna? And, if a small slot antenna "works" at mobile phone cellular and radar frequencies, would a very large hole with proper (slot) dimensions in a large enough building (barn, aircraft hanger, office tower) work for some HF bands?

To create a more directive radiation pattern, the size of the antenna must be increased. This can be done with simple resonant antennas like the dipole and the loop, but it is usually difficult to control the side lobe levels of these antennas. A waveguide slot array antenna is mainly used for high gain flat antennas in millimeter-wave wireless communication systems due to their unique features such as lower loss in comparison with microstrip antennas, and simpler structure compared with ... A 28-GHz U-slot Microstrip Patch Antenna for 5G Applications The radiation patterns of an antenna provide the information that describes how the antenna directs the energy it radiates. As As stated earlier, an antenna cannot radiate more total energy than is delivered to its input terminals. directional radiation pattern while the microstrip slot … The proposed antenna consists of a microstrip patch antenna and a microstrip slot antenna where the slot antenna is positioned at the ground plane underneath the...Frequency Reconfigurable Microstrip Patch-Slot Antenna with Directional Radiation Pattern.
