Designing a log-periodic antenna requires first determining the coverage frequency band, with its operating frequency typically ranging between 30 MHz and 3 GHz. Its structure consists of multiple parallel dipoles with gradually changing lengths. During operation, the half-wavelength corresponding to the lowest operating frequency must first be calculated and used as the physical dimension of […]

High Bandwidth Optimization In the 5G Sub-6GHz band,

Horn antenna gain is determined by the aperture area, operating wavelength, and efficiency (typically taken as 0.6). The calculation formula is: 4π multiplied by the area multiplied by the efficiency, divided by the square of the wavelength. A larger aperture area or a shorter wavelength results in higher gain, which significantly enhances the directional transmission

Selection depends on matching the frequency (e.g., 2-40 GHz), ensuring gain error < ±0.5 dB and VSWR < 1.3. Understanding Frequency Each horn antenna corresponds to a specific WR waveguide standard; for example, WR-28 covers 26.5 to 40 GHz, with internal waveguide dimensions of 7.112 mm x 3.556 mm. The frequency level directly relates to

Selection should be based on frequency to determine size, for example, WR-90 corresponds to 8.2-12.4 GHz; During installation, strictly control the E-plane static bend radius to be greater than 64mm to prevent VSWR deterioration causing signal reflection. Size Size selection must first match the operating frequency band based on EIA standards (such as WR-75). For

Waveguide conductive gaskets typically use silicone rubber filled with silver or nickel particles, with a standard thickness of about 0.69mm, capable of providing shielding effectiveness exceeding 100dB. When selecting, choose O-type or D-type cross-sections based on WR flange dimensions (e.g., WR28); for high-pressure environments, metal skeleton reinforced types are recommended to prevent cold flow. The

Test broadband waveguide antennas via VNA calibrated with WR-90 standards, measuring S11 (<-10dB) from 26.5-40GHz. In far-field (15λ away), compare with a reference antenna to record gain (>12dBi) and VSWR (<1.5), validating consistent mode propagation and impedance match. Pre-Test Preparation Pre-test preparation requires building standardized test conditions, including anechoic chamber environment verification (quiet zone size

Waveguide components enhance EMC with ultra-low insertion loss (<0.2dB at 10GHz) and robust shielding; precision-machined metal walls (roughness <0.8μm) suppress leakage, confining signals via mode propagation while blocking interference. Low Loss In high-frequency signal transmission, the low-loss characteristic of waveguides stems from the full constraint of electromagnetic waves by their metal enclosed structure. The inner
