“…C-SOLR has been introduced on the patch without affecting the radiation characteristics of the antenna. The proposed antenna offers 400 MHz, 2:1 VSWR bandwidth which is significantly higher than that of the bandwidth obtained by other techniques like changing the feed of the patch proposed in [2], [14]. The proposed antenna offers simulated directivity and gain of 6.1 dB and 4.25 dB respectively.…”

“…The 'Long Term Evolution' (LTE) and 'Long Term Evolution-Advanced' (LTE-A) new standards for 4G, require large bandwidths (up to 200MHz) and it is expected, that newer standards will require even higher bandwidths [6][7][8][9]. In that respect, several techniques were discussed in the literature, for bandwidth improvement, including changing the feed type, stacking the patch, modifying the geometry of the patch, and changing the feed location [10][11][12][13][14]. Each method has its own tradeoffs, particularly involving the size of the antenna.…”

“…Our first attempts applying FP to a rectangular and supershaped patch antennas with two symmetrical feeding points are presented in Refs. [14][15][16]. Aiming at maintaining the antenna dimensions to minimum, a second dielectric substrate can be used, sharing the same ground plane with the first.…”

“…Namely their common resonant frequency is pulled downwards and upwards, while the original common resonance is retained. Regarding this concept, we started modifying the feeding network of classical patch antennas observing an impressive bandwidth enhancement, just as predicted by FP in BPF synthesis [13][14][15][16]. Advantages offered by BPF but without any reference to FP were also exploited by other researchers [17,18].…”

A novel antenna design technique is proposed, which offers bandwidth enhancement up to the limits defined by element radiation efficiency. The employed technique is referred as frequency pulling (FP) as it mimics the 'insertion loss design methodology of bandpass filters'. This is essentially a wideband matching approach pushing the antenna efficiency to the limits set up by radiation efficiency. There are three options towards this trend: (i) first to enhance a single element bandwidth (compact element) exploiting its possibly multiple symmetrical feeding points as distinct resonator ports, (ii) frequency pulled array as to design a small antenna array (less than about 10 elements) where each element acts as a resonator and (iii) second order frequency-pulled array as to build a small array using compact elements of category (i). Similar to the band-pass filter design, all antennas or distinct-port circuits resonate at the same resonant frequency when isolated, cascading two or more of them; FP yields to multiple-overlapping successive resonances in their overall response. Although the proposed technique is general within this first effort, it is applied to simple patch antenna elements exhibiting multiple symmetrical feeding points, namely two-for rectangular, four-for square and five-for pentagonal. The third option is applied to an array of three compact 4-feeding point square elements offering triple bandwidth with respect to the already wideband single element. However, this is achieved at the expense of a significant beam squint. Thus, in general, these wideband compact elements should be used within a classical array design. Further bandwidth enhancement using FP to antenna elements with inherent multiple resonances as patches with slots or truncated edges constitutes our next task. Their inherent wider bandwidth in radiation efficiency is expected to allow multiply higher bandwidths when exploited with our FP technique.
