Types of Antennas Explained (Deep Dive)
Welcome to Part 2: Types of Antennas Explained (Deep Dive) — your detailed guide to understanding every antenna category used today in WiFi, TV, RF, ham radio, 5G, satellite systems, and more.
This guide expands on the basics and gives you a complete, human-friendly breakdown of how each antenna type works, what it’s used for, and how to choose the right one.
📡 1. Omnidirectional Antennas
An omnidirectional antenna radiates signals in all directions (360° horizontally). Think of it like a glowing ball of RF energy.
Best for:
- WiFi routers
- Indoor/Outdoor TV antennas
- Handheld ham radios (HTs)
- Bluetooth devices

TP-Link 9dBi High-Gain WiFi Antenna
Improves WiFi coverage for routers and adapter cards.
Price: $12–$20
ID: ANT-OMNI-TPL01
📡 2. Directional Antennas
Directional antennas focus their energy in a specific direction, giving higher gain and long-range performance.
Main directional antenna categories include:
- Yagi antennas
- Panel antennas
- Log-periodic antennas
- Dish antennas
📌 Yagi Antennas
A Yagi antenna uses multiple elements to produce high forward gain. Commonly used for:
- TV reception
- Ham radio VHF/UHF
- Long-distance WiFi links
📌 Panel Antennas
A flat directional antenna often used for:
- Indoor LTE/5G boosters
- Hotspots
- WiFi extenders
📌 Dish Antennas
These provide extremely focused beamwidth for:
- Satellite internet
- Point-to-point microwave links
- Long-range ham radio operations

📡 3. Dipole Antennas
A dipole antenna is the simplest and most widely used antenna ever created. It consists of two equal-length conductive elements.
Used for:
- Broadcast radio
- Ham radio
- WiFi (older devices)
- TV antennas
Dipoles provide excellent balance between gain, simplicity, and wide availability.
📡 4. Loop Antennas
Loop antennas are popular for HF and AM radio because they reduce electrical noise and deliver sharper directionality.
Common Uses:
- AM broadcast listening
- HF amateur radio reception
- RF direction finding

KA700 Active Loop HF Antenna
Excellent for HF radio enthusiasts and SWL listeners.
Price: $50–$99
ID: ANT-LOOP-KA700
📡 5. Monopole Antennas
A monopole antenna uses a single vertical conductive rod above a ground plane. Most car antennas and vertical ham radio antennas use this design.
Best for:
- Mobile radios
- Car FM antennas
- CB radios
- Marine radios
📡 6. Patch / Microstrip Antennas
These are flat, compact antennas used in:
- Smartphones
- Drones (FPV systems)
- GPS receivers
- IoT devices
They are small, lightweight, low-power, and ideal for consumer electronics.
📡 7. Satellite Dish Antennas
Satellite antennas are ultra-directional dishes designed to focus weak space signals onto a feed horn.
Used for:
- Starlink internet
- Satellite TV (DISH, DirecTV)
- Weather satellite reception
- Amateur satellite communication
🛒 Recommended Dish Antenna (Impact.com Affiliate)
GEOSATpro Ultra Dish
Great for free-to-air and satellite enthusiasts.
Price: $120–$200
ID: ANT-DISH-GS01
📡 8. Log-Periodic Antennas
A log-periodic antenna looks like a Yagi but is built for wideband frequency coverage.
Applications:
- TV antennas
- 5G/LTE boosters
- RF research
- Wideband ham radio scanning
📡 9. Helical Antennas
Helical antennas are spiral-shaped antennas used in:
- GPS systems
- Satellite communications
- High-gain directional WiFi links
They provide excellent circular polarization for space-based signals.
📡 10. 5G Antennas
5G antennas are designed to handle a large range of frequencies — from 600 MHz low-band to 39 GHz mmWave.
Types include:
- 5G panel antennas
- 5G outdoor CPE antennas
- 5G Omnidirectional towers
- 5G mmWave arrays

📡 11. FPV Drone Antennas
Used in racing drones and FPV video systems. Common types include:
- Pagoda antennas
- Cloverleaf circular antennas
- Stubby LHCP/RHCP antennas
These antennas are designed to reduce interference and provide clean video signals.
📡 12. Marine Antennas
Marine antennas are corrosion-resistant and optimized for:
- VHF maritime radios
- AIS navigation
- Weather alert radios
