Questions about the Antenna Types poster

What’s on the Antenna Types poster?

A 5-row table: Antenna · Pattern · Typical use. Pattern shape is usually what decides the family. Half-wave dipole — Doughnut, broadside — Reference, VHF and UHF; Monopole over ground — Half a dipole pattern — Vehicles, handsets; Yagi-Uda — Directional, moderate gain — TV, point to point; Patch, microstrip — Hemispherical, low profile — GPS, phones, arrays; Parabolic dish — Pencil beam, high gain — Satellite, radar links. Physical size scales with wavelength, so a low-frequency antenna is either large or inefficient. There is no way around it.

Who is the Antenna Types poster for?

Antenna Types belongs to the Electrical Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning electromagnetics can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the Antenna Types poster?

Use it to shortlist an antenna once the frequency and the coverage pattern are known. A wall chart earns its place by being glanceable from where the work is happening, so Antenna Types belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.

What other posters go with Antenna Types?

Antenna Fundamentals, Boundary Conditions and Link Budget sit alongside Antenna Types in the Electrical Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Antenna FundamentalsBoundary ConditionsLink Budget

Is the Antenna Types poster free to download and print?

Yes. Antenna Types downloads as a free PDF with no account, no email and no watermark, like everything else in the Electrical Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence

What size does the Antenna Types poster print at?

Antenna Types is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Antenna Types loses nothing.Printing guide
