Slot antenna resonant frequency formula

Oct 2, 2017 ... antenna with vertical slots using Applying Adaptive ... for analysis of the resonant frequency of a microstrip rectangular patch antenna with.

This means that there are two points where the impedance is 50 Ω somewhere along the resonant length (x) axis of the element and this is where you would typically connect to the antenna. The possibility to connect to the patch at other impedance points is quite useful and impedances up to 200 Ω are common. Design And Analysis Of Compact U Slot Microstrip Patch There is a reduction of resonance frequency from 2. 44GHz to 2. 10GHz i. e. around 15 % with the proposed antenna compared to the square patch of the same size. The antenna operating frequency range is 2. 41GHz -2. 47GHz with VSWR less than 2. It exhibits remarkable gain which corresponds to the gain of 5. 32dB. Microstrip Antenna - Design - Antenna-Theory.com All of the parameters in a rectangular patch antenna design (L, W, h, permittivity) control the properties of the antenna. As such, this page gives a general idea of how the parameters affect performance, in order to understand the design process. First, the length of the patch L controls the resonant frequency as seen here. This is true in Multi-Band Circularly Polarized Slot Antenna for GPS
