Microstrip Patch Antenna Designing at 2.4 GHz Frequency Microstrip Patch Antenna − Designing at 2.4 GHz Frequency. 129 . 2. Designing For designing of a microstrip patch antenna, we have to select the resonant frequency and a dielectric medium for which antenna is to be designed. The parameters to be calculated are as under. Width (W): Slot Antenna - an overview | ScienceDirect Topics The resonant half-wavelength slot antenna is desirable because of its compact size; however, it has large input impedance, typically larger than 300 Ω, which makes it difficult to match to. This can be circumvented by using an offset microstrip feed or the folded slot antenna, which
Design Narrow Slot Antenna for Dual Frequency - PIERS
Input Impedance and VSWR vs. Frequency Plots for Three Values of Slot Length (l 1 = 29.4, 31.4, and 33.4mm) With increase in the slot length, resonance frequency decreases and input impedance locus rotates clockwise Slot Length Variation in Offset-fed Cavity Backed slot Antenna Design of Modified Bowtie Antenna for Wireless Applications ... An empirical formula of resonant frequency of bow- tie antennas is presented, which is based on the cavity model of microstrip patch antennas as in [2]. A procedure to design a bow-tic antenna using generic algorithm (GA) in whichthe formula is taken as a fitness function is also given. An optimized bow-tic antenna by genetic algorithm is measured.

Non-Resonant Slotted Waveguide Antenna Design Method
A resonant device is one, which gives better output at certain narrow band of frequencies. Antennas are such resonant devices whose impedance if matched, delivers a better output. The power radiated by an antenna, will be effectively radiated, if the antenna impedance matches the free space impedance.
