A circular antenna
ensures maximum readability extremely quickly, while ASIC radio technology provides high sensitivity and greater read accuracy.
The paper "An Antenna Array Sidelobe Level Reduction Approach through Invasive Weed Optimization" addresses both the linear antenna array and the circular antenna
A Novel Particle Swarm Optimization Based Optimal Design Of Three-Ring Concentric Circular Antenna
With its extensive router heritage, TP-LINK's expertise was an integral contribution to OnHub's design, in particular its unique circular antenna
with 13 built-in, hidden antennas that reduce network interference and optimize network connectivity.
6-8 the lens must be placed at the focal point of the signal source, which is a circular antenna
mounted on the frequency converter.
The first one consists of a circular antenna
array in which the different elements are fed with signals having the same amplitude and a progressive phase shift, such that the total delay between the first and the last element is an integer multiple l of 2[pi] [5,6].
The antenna elements constitute a circular antenna
array, as it is illustrated in the Figure 1 .
Jones, "Comparison of planar and circular antenna
configurations for breast cancer detection using microwave imaging," Progress In Electromagnetics Research, Vol.
Figure 2 shows the two-element linear array with two cavity-backed electromagnetically coupled circular metallic disc elements. The circular antenna
element, cavity and supporting rectangular plate are made of aluminum.
Chakravarthy and Rao  propose to use a particle swarm optimization- (PSO-) based algorithm to synthesize the beam pattern of a circular antenna
Since such metal walls are not practical and would not exist in the antennas described in Section 2, it is reasonable to analyse various circular antenna
arrays in these scenarios.
